Is depression associated with oral health outcomes in adults and elders? A systematic review and meta-analysis

Gender differences in the association between transitions in depressive symptoms and oral health among older adults with chronic conditions

BACKGROUND

Oral health influences the quality of life of older adults. Further, depression is negatively associated with oral health. However, little is known about this relationship among older adults with chronic health conditions. Additionally, since oral health and depression differ between genders, this study aimed to investigate the effect of transitions in depressive symptoms on oral health among older adults with chronic health conditions by gender.

METHODS

We used data from the Korean Longitudinal Study of Aging (2020-2022). The study sample comprised 2836 older adults (1104 men; 1732 women). We adopted multiple linear regression to examine the association between depressive symptom transitions and oral health by gender.

RESULTS

The new onset depression symptoms were significantly associated with the deterioration of oral health in men (β = -5.4308) and women (β = -4.8328). Our study showed a gender-specific association between new onset depressive symptoms and particular domains of oral health. For men, the association was slightly more negative in psychosocial function (β = -2.1177) while women presented lower GOHAI scores in both the physical function domain (β = -1.8800) and the psychosocial function domain (β = -1.8801).

LIMITATIONS

The data used in this study were self-reported via a survey; thus, self-report bias may be a relevant concern.

CONCLUSION

To prevent deterioration in oral health, depressive symptoms must be detected and addressed early among older adults with chronic conditions. This study underscores the importance of interventions that consider gender differences in the association between depressive symptoms and psychosocial and physical functioning.

Depression, stress-related disorders and risk for dental caries and periodontitis: A bidirectional and multivariable Mendelian randomization study

AIMS

Our Mendelian randomization (MR) analysis focused on investigating the bidirectional relationships between major depressive disorder (MDD), anxiety and stress-related disorder (ASRD), and dental caries as well as periodontitis.

MATERIALS AND METHODS

We used summary statistics from two studies: an MDD genome-wide association study (GWAS) including 135,458 cases with 344,901 controls and a Lundbeck Foundation Initiative for Integrative Psychiatric Research (iPSYCH) GWAS based on 12,655 ASRD individuals and 19,225 controls from Denmark. GWASs on dental caries and periodontitis were based on the Gene-Lifestyle Interactions in Dental Endpoints (GLIDE) consortium. We employed different MR approaches, such as inverse-variance weighted (IVW), MR-Egger, weighted median, and MR-PRESSO, to calculate causal effects.

RESULTS

Single-variable MR analysis revealed that ASRD was potentially significantly associated with decayed, missing, and filled tooth surfaces (DMFS) (β = 0.056; 95 % CI: 0.009, 0.103; p = 0.018). Periodontitis was suggested to be causally related to increased ASRD risk (OR = 1.143, 95 % CI: 1.008, 1.298; p = 0.038). According to the multivariable MR analysis, no significant associations were detected between MDD and ASRD with dental caries and periodontitis, and vice versa.

CONCLUSIONS

ASRD demonstrated a potential association with DMFS, and periodontitis was found to potentially impact ASRD according to single-variable MR analysis. Nevertheless, no significant associations were identified between MDD, ASRD, dental caries, or periodontitis after adjusting for smoking status and education level. Hence, more robust genetic instruments are required to validate and reinforce our findings.

Tooth loss and depression in Chilean participants of the National Health Survey 2016-2017: Oral and social functions mediation analysis

BACKGROUND

Previous studies have indicated the association between poor oral health and depression in adults. This study evaluated oral and social functions contribution to the association between tooth loss and depressive symptoms in Chilean individuals.

METHODS

We used data from the Chilean National Health Survey. The number of remaining teeth (≤19 versus ≥20 teeth) and anterior tooth losses were the exposure variables. Outcome was depression, measured through a self-report question and with the Composite International Diagnostic Interview - Short Form (CIDI SF). Mediating variables were determined by five questions, including problems regarding "speaking", "pain and suffering", "eating", "daily activities", and "social relationships". We performed logistic regression models adjusted by multiple confounders variables. Finally, we calculated indirect, direct effect, total effect, and the proportion mediated (PM).

RESULTS

We included 5383 participants. The self-reported depression and suspected depression prevalence were 22,1 % and 14,0 % respectively. The total effect of fewer remaining teeth (≤19) on self-reported depression was 1.21 (95 % CI 1.02-1.44), and 1.09 (95 % CI 0.90-1.33) for suspected depression. All five variables of oral and social functions significantly mediated the association between tooth loss and depression. Feeling uncomfortable when speaking or eating discomfort were the most significant mediators.

LIMITATIONS

The mediation analysis should be interpreted with caution due to the cross-sectional design.

CONCLUSIONS

Deterioration of oral and social functions was a significant mediator in the association between tooth loss and depression, in particular feeling uncomfortable when speaking or eating. This mechanism should be considered in interventions to improve mental health.

Depression and assets during the COVID-19 pandemic: A longitudinal study of mental health across income and savings groups

The prevalence of depression in U.S. adults during the COVID-19 pandemic has been high overall and particularly high among persons with fewer assets. Building on previous work on assets and mental health, we document the burden of depression in groups based on income and savings during the first two years of the COVID-19 pandemic. Using a nationally representative, longitudinal panel study of U.S. adults (N = 1,271) collected in April-May 2020 (T1), April-May 2021 (T2), and April-May 2022 (T3), we estimated the adjusted odds of reporting probable depression at any time during the COVID-19 pandemic with generalized estimating equations (GEE). We explored probable depression-defined as a score of ≥10 on the Patient Health Questionnaire-9 (PHQ-9)-by four asset groups, defined by median income (≥$65,000) and savings (≥$20,000) categories. The prevalence of probable depression was consistently high in Spring 2020, Spring 2021, and Spring 2022 with 27.9% of U.S. adults reporting probable depression in Spring 2022. We found that there were four distinct asset groups that experienced different depression trajectories over the COVID-19 pandemic. Low income-low savings asset groups had the highest level of probable depression across time, reporting 3.7 times the odds (95% CI: 2.6, 5.3) of probable depression at any time relative to high income-high savings asset groups. While probable depression stayed relatively stable across time for most groups, the low income-low savings group reported significantly higher levels of probable depression at T2, compared to T1, and the high income-low savings group reported significantly higher levels of probable depression at T3 than T1. The weighted average of probable depression across time was 42.9% for low income-low savings groups, 24.3% for high income-low savings groups, 19.4% for low income-high savings groups, and 14.0% for high income-high savings groups. Efforts to ameliorate both savings and income may be necessary to mitigate the mental health consequences of pandemics.

Experience of Discrimination and Oral Health Self-Perception: A Cross-Sectional Study among Brazilian Adults

This cross-sectional study investigated the association between experiences of discrimination and oral health self-perception among a probabilistic cluster sample of Brazilian adults who participated in the 2013 National Health Survey. Oral health self-perception was categorized into three groups (very good + good; fair; poor + very poor). Reported experiences of discrimination included attributions based on the respondent's race/skin color, social class, income, occupation, illness, sexual orientation, religion, sex, and age. Covariates included sociodemographic data, oral health conditions, access to healthcare services, health habits, mental health, and participation in social and/or religious activities. Data were analyzed using ordinal logistic regression for non-proportional odds, considering sample weights and complex samples. Among 60,202 adults, 5.84% perceived their oral health as poor + very poor, with a significantly higher proportion among those experiencing discrimination (9.98%). Adults who experienced discrimination were 1.39 times more likely to report a "poor/very poor/fair" oral health self-perception compared to those who did not experience discrimination. Those who suffered discrimination were 1.28 times more likely to have a "very poor/poor" oral health self-perception than their counterparts who were not affected by discrimination. These findings underscore the importance of considering discrimination experiences as part of the social determinants influencing oral health.

A rural teledentistry care experience: a geriatric approach to assessing oral health status and treatment needs in older adults from a Mapuche community in Chile

Background

Limited attention has been given to oral health challenges faced by older Indigenous populations, especially in rural settings, where disparities exist. This study aims to assess oral health in a rural Mapuche community in southern Chile, utilizing geriatric technology support, and exploring the connection between geriatric health and oral well-being to fill a gap in this context.

Methods

A cross-sectional study was conducted involving 76 independent older adults from a rural Mapuche community who required dental care. Assessments were in a remote care setting gathering extensive data including comprehensive geriatric assessments, medical and dental conditions using a geriatric teledentistry platform (TEGO®). Statistical analysis involved descriptive analysis, logistic regression, and both multiple correspondence analysis and k-means cluster analysis.

Results

The sample comprised individuals with limited formal education and a high degree of vulnerability. Geriatric assessments unveiled cognitive deterioration, frailty, depression risk, and multimorbidity. A distribution of the DMFT index, number of remaining teeth, number of occluding pairs, number of teeth with restorative needs and other relevant clinical findings was conducted based on sociodemographic, and medical-geriatric-dental characteristics, and additionally, a Multinomial Logistic Regression Analysis of Dentition Variables in Relation to Geriatric Assessments was performed. The dental burden was substantial, with an average DMFT index of 25.96 (SD 4.38), high prevalence of non-functional dentition (89.3%), periodontal disease (83%), xerostomia (63.2%) and oral mucosal lesions (31.5%). Age, lower education, depression, daily medication number and sugary consumption frequency were associated with a decreased average number of teeth (p < 0.05). Multiple correspondence analysis and k-means cluster analysis identified 4 clusters, with the edentulous and functional dentition groups being the most distinct.

Conclusion

This study uncovers a substantial dental burden and intricate medical-geriatric conditions interlinked among Indigenous older adults in a rural Chilean Mapuche community. The implementation of a geriatric technological ecosystem in the community enabled the resolution of less complex oral health issues and facilitated remote consultations with specialists, reducing the necessity for travel to health centers. This underscores the need for innovative dental public health initiatives to address health disparities and improve the overall well-being of older Indigenous adults.

Relationship between the number of lost teeth and the occurrence of depressive symptoms in middle-aged adults: a cross-sectional study

BACKGROUND

Many recent studies suggest the existence of a relationship between oral health and the occurrence of depressive symptoms. The aim of this study was to assess the relationship between the number of lost teeth and the occurrence of depressive symptoms in middle-aged adults.

METHODS

An analysis was performed on the data obtained from the PONS project (POlish-Norwegian Study), conducted in the Świętokrzyskie Province in Poland in 2010-2011. The research material included the cross-sectional data of 11,901 individuals aged 40-64 years (7967 women). Depressive symptoms, used as outcome variables, were assessed with a questionnaire. The participants provided the responses to questions concerning the occurrence of eight symptoms over the last 12 months. The answers were scored as 1 point or 0 points. The participants were divided into three tercile groups based on their total scores: no or mild (0-2 points), moderate (3-5 points), and severe depressive symptoms (6-8 points). The self-reported number of lost teeth was analysed according to the following categories: 0-4, 5-8, 9-27, and a complete lack of natural teeth. Multivariable logistic regression analysis for depressive symptoms was used in relation to the number of lost teeth. The following covariates were included in the adjusted model: age, sex, place of residence, education, marital status, BMI, diabetes status, stressful life events in the last year, use of antidepressants, smoking, and sugar and sweet consumption.

RESULTS

The likelihood of both moderate (OR = 1.189; 95%CI: 1.028-1.376; p < .020) and severe (OR = 1.846; 95%CI: 1.488-2.290; p < .001) depressive symptoms showed the strongest relationship with a total lack of natural teeth. A loss of more than 8 natural teeth was also significantly associated (OR = 1.315; 95%CI: 1.075-1.609; p < .008) with the occurrence of severe depressive symptoms.

CONCLUSIONS

The loss of natural teeth was positively related to the occurrence of depressive symptoms in middle-aged adults. Thus, there is an urgent need to intensify stomatological prophylaxis, education and treatment for middle-aged individuals.

Depression Symptoms Linked to Multiple Oral Health Outcomes in US Adults

BACKGROUND

Individuals with mental illness have poor oral health compared to those without mental health conditions. However, the literature is still lacking regarding the specifics of this relationship.

OBJECTIVE

This study aims at examining the relationship between depression and oral health problems such as oral conditions, access to dental care, and oral hygiene measures.

METHODS

A cross-sectional study using a secondary data analysis of 9,693 participants from the 2017 to March 2020 prepandemic National Health and Nutrition Examination Survey (NHANES). The independent variable was severity of depressive symptoms as measured by the Patient Health Questionnaire-9 (PHQ-9). Proportional odds and binary logistic regression were used to calculate crude and adjusted odds ratios (AORs) between depression and 8 oral health outcomes and oral hygiene-related behaviors.

RESULTS

After adjusting for sociodemographics, health conditions, and behaviors, individuals with depression were significantly more likely to have dental aches in the past year (AOR = 1.70; 95% confidence interval [CI], 1.13-2.56), difficulty getting dental care when needed (AOR = 1.93; 95% CI, 1.45-2.58), and difficulty at their jobs due to a problem in their mouth (AOR = 1.63; 95% CI, 1.07-2.49) compared to individuals without depression.

CONCLUSION

Individuals with depressive symptoms often neglect oral hygiene and self-care practices and are less likely to seek medical care for oral health problems, making them at increased risk of poor oral health outcomes. These findings can be applied by dentists, psychologists, and therapists to increase awareness of links between depression and oral health and to encourage patients with depression to seek oral hygiene preventative care.

KNOWLEDGE TRANSFER STATEMENT

Health care professionals can be on the frontline in creating awareness in the general public about the links between depression and oral health and hygiene. Applying the findings from this study can help communicate about the relationship between depression and poor oral health and relieve some burden on the American health care sector, which often struggles to provide medical care to patients with depression and oral health issues.

Depression and dental caries in US adults, NHANES 2015-2018

PURPOSE

This study aimed to investigate the link between depression and untreated dental caries among adults in the United States.

METHODS

Data were collected from the National Health and Nutrition Survey (2015-2018); respondents aged 20 years or older who completed a patient health questionnaire and underwent a comprehensive oral examination were included. Participants were categorized into three groups according to depressive symptoms as follows: those with no, mild, or moderate to severe depression. Data were weighted, and multiple potential covariates were included in the analysis to provide national estimates and account for the complex sample design. A multivariable weighted logistic regression model was performed to test the hypothesis that varying degrees of depression in American adults are associated with untreated dental caries. Subgroup analyses were performed based on age and gender after adjusting for potential covariates. A P value of <.05 was considered significant.

RESULTS

Among 8740 participants, the prevalence of untreated coronal and root caries was 20.50% and 12.92%, respectively. Moderate to severe depression was a significant risk factor (odds ratio, 1.25; 95% confidence interval, 1.09-1.66) for untreated root caries. The risk of untreated root caries increased by 87% in young adults (aged 20-44 years) and by 46% in women with moderate to severe depression. The suest analysis revealed that the impact of moderate to severe depressive disorder on untreated root caries was non-significantly different between the age subgroup (p=0.09) and sex subgroup (p=0.51). However, depression was non-significantly associated with untreated coronal caries (mild depression: OR, 1.07; 95% CI, 0.85-1.34; moderate to severe depression 1.06; 95% CI, 0.83-1.36; respectively).

CONCLUSION

The results of this study suggested a significant association between moderate and severe depression and untreated root caries; however, the association with untreated coronal caries was non-significant. In the United States, moderate and severe depression in adults is associated with root caries.

The role of Toll-like receptors in neuropsychiatric disorders: Immunopathology, treatment, and management

Neuropsychiatric disorders denote a broad range of illnesses involving neurology and psychiatry. These disorders include depressive disorders, anxiety, schizophrenia, bipolar disorder, attention deficit hyperactivity disorder, autism spectrum disorders, headaches, and epilepsy. In addition to their main neuropathology that lies in the central nervous system (CNS), lately, studies have highlighted the role of immunity and neuroinflammation in neuropsychiatric disorders. Toll-like receptors (TLRs) are innate receptors that act as a bridge between the innate and adaptive immune systems via adaptor proteins (e.g., MYD88) and downstream elements; TLRs are classified into 13 families that are involved in normal function and illnesses of the CNS. TLRs expression affects the course of neuropsychiatric disorders, and is influenced during their pharmacotherapy; For example, the expression of multiple TLRs is normalized during the major depressive disorder pharmacotherapy. Here, the role of TLRs in neuroimmunology, treatment, and management of neuropsychiatric disorders is discussed. We recommend longitudinal studies to comparatively assess the cell-type-specific expression of TLRs during treatment, illness progression, and remission. Also, further research should explore molecular insights into TLRs regulation and related pathways.

Oral health of people with emotional disorders: A systematic review and meta-analysis

OBJECTIVES

This study aims to determine the association between severe mental disorders and oral health among individuals over 18 years of age.

METHODS

An electronic search was conducted in six electronic databases and gray literature. Qualitative and quantitative analyses were performed on studies that met the inclusion criteria. The methodology of the included studies was assessed using the Joanna Briggs Institute Critical Appraisal tool. A meta-analysis of proportions with a random effect was carried out. The certainty of evidence was evaluated using the GRADE tool.

RESULTS

After searching the databases, 5,734 references were retrieved, and twenty articles were selected for synthesis. Considering the DMFT index between the groups with mental disorders and the control group, the values of the DMFT index were higher among individuals with schizophrenia [MD = 5.27; 95% CI = 4.13 - 6.42; I2 = 35%] and bipolar disorder [MD = 1.90; 95% CI = 0.87 - 2.93]. Values were lower among individuals with obsessive-compulsive disorder [MD = -0.85; 95% CI = -1.46-0.24]. The risk of bias was considered low for 16 studies, and four were classified with a moderate risk of bias. The certainty of evidence was very low.

CONCLUSION

Patients with schizophrenia and bipolar disorder exhibit increased frequency in the number of decayed, missing, or filled teeth. There was no effect in relation to periodontal probing depth, plaque index, and TMD, but the evidence is still uncertain for this outcome.

CLINICAL RELEVANCE

These findings underscore the need for a comprehensive health approach.

Association between Oral Health and Depressive Symptoms in Chinese Older Adults: The Mediating Role of Dietary Diversity

Diet is a modifiable factor in healthy population aging. Additionally, oral health and diet are important factors affecting depressive symptoms. To assess the mediating role of dietary diversity (DD) in oral health and depressive symptoms in older adults, we selected 8442 participants aged ≥ 65 years from the 2018 Chinese Longitudinal Health Longevity Survey (CLHLS) for a cross-sectional study. Depressive symptoms were determined based on scores on the 10-item Center for Epidemiologic Studies Depression Scale (CESD-10). Dietary diversity scores (DDS) were established based on the frequency of intake of food groups. Oral health was measured by denture use and toothbrushing frequency. Stepwise multiple linear regression and PROCESS macros were used for mediated effects analysis and testing. The sample had a positive detection rate of 44.1% for depressive symptoms, 40.8% for denture use, and 41.9% for once-a-day toothbrushing. Denture use (ρ = -0.077, p < 0.01) and toothbrushing frequency (ρ = -0.115, p < 0.01) were negative predictors of depressive symptoms in older adults. DD significantly mediated the association between denture use (indirect effect -0.047; 95%CI: -0.068-0.028; p < 0.001), toothbrushing frequency (indirect effect -0.041; 95%CI: -0.054-0.030; p < 0.001), and depressive symptoms. Denture use and toothbrushing frequency not only directly reduce the risk of depressive symptoms in older adults, but also indirectly affect depressive symptoms through DD.

The Longitudinal Reciprocal Relationships of Tooth Brushing Behaviors Between Underserved Children and Their Caregivers

BACKGROUND

Tooth brushing is effective in preventing early childhood caries. However, it is unclear how children's and caregiver's tooth brushing are reciprocally related.

PURPOSE

The current study investigated whether the longitudinal relationships between children and caregiver tooth brushing are moderated by a caregiver-targeted child oral health intervention and caregiver depression.

METHODS

Secondary analysis of a randomized clinical trial that tested whether caregiver-targeted oral health text messages (OHT) outperformed child wellness text messages (CWT) on pediatric dental caries and oral health behaviors (n = 754, mean child age = 2.9 years, 56.2% Black, 68.3%

RESULTS

Within-participants analyses revealed that caregiver tooth brushing at Months 4 and 12 positively predicted their child's tooth brushing at Months 12 and 24 for caregivers in the OHT condition with low depressive symptoms (i.e., moderation by depressive symptoms and condition). Similarly, children's tooth brushing at Month 4 positively predicted caregiver tooth brushing at Month 12 for caregivers in the OHT condition with low depressive symptoms. There were no significant associations among participants in the CWT condition, regardless of depressive symptoms.

CONCLUSIONS

Child and caregiver tooth brushing have reciprocal influences, but only for those in the OHT condition with low depressive symptoms.

Development and validation of a nomogram for predicting depressive symptoms in dentistry patients: A cross-sectional study

Depressive symptoms are frequently occur among dentistry patients, many of whom struggle with dental anxiety and poor oral conditions. Identifying the factors that influence these symptoms can enable dentists to recognize and address mental health concerns more effectively. This study aimed to investigate the factors associated with depressive symptoms in dentistry patients and develop a clinical tool, a nomogram, to assist dentists in predicting these symptoms. Methods: After exclusion of ineligible participants, a total of 1355 patients from the dentistry department were included. The patients were randomly assigned to training and validation sets at a 2:1 ratio. The LASSO regression method was initially employed to select highly influrtial features. This was followed by the application of a multi-factor logistic regression to determine independent factors and construct a nomogram. And it was evaluated by 4 methods and 2 indicators. The nomograms were formulated based on questionnaire data collected from dentistry patients. Nomogram2 incorporated factors such as medical burden, personality traits (extraversion, conscientiousness, and emotional stability), life purpose, and life satisfaction. In the training set, Nomogram2 exhibited a Concordance index (C-index) of 0.805 and an Area Under the Receiver Operating Characteristic Curve (AUC) of 0.805 (95% CI: 0.775-0.835). In the validation set, Nomogram2 demonstrated an Area Under the Receiver Operating Characteristic Curve (AUC) of 0.810 (0.768-0.851) and a Concordance index (C-index) of 0.810. Similarly, Nomogram1 achieved an Area Under the Receiver Operating Characteristic Curve (AUC) of 0.816 (0.788-0.845) and a Concordance index (C-index) of 0.816 in the training set, and an Area Under the Receiver Operating Characteristic Curve (AUC) of 0.824 (95% CI: 0.784-0.864) and a Concordance index (C-index) of 0.824 in the validation set. Net Reclassification Improvement (NRI) and Integrated Discrimination Improvement (IDI) indicated that Nomogram1, which included oral-related factors (oral health and dental anxiety), outperformed Nomogram2. We developed a nomogram to predict depressive symptoms in dentistry patients. Importantly, this nomogram can serve as a valuable psychometric tool for dentists, facilitating the assessment of their patients' mental health and enabling more tailored treatment plans.

The relationship between self-reported poor mental health and complete tooth loss among the US adult population in 2019

Objective

Very little is known about the association between poor mental health and poor oral health outcomes in the United Sates. This study investigated the prevalence of complete tooth loss among those with and without perceived poor mental health in a nationally representative sample of noninstitutionalized U.S. adults.

Methods

Using a cross-sectional study design, we analyzed the 2019 Medical Expenditures Panel Survey to determine the unweighted and weighted prevalence of complete tooth loss among adults. Chi-squared and multivariate logit regression with marginal effects were used to measure the association between complete tooth loss and perceived poor mental health, controlling for respondent characteristics.

Results

The prevalence of adults (ages 18 and older) experiencing complete tooth loss was 6% (95% CI: 5.6-6.4). Individuals who have perceived poor mental health were 1.90 percentage points (pps) more likely to report missing all their natural teeth (P = 0.006: 95% CI: 0.5-3.3). Other relevant predictors of complete tooth loss included current smoking status (5.9 pps; 95% CI: 4.5 to 7.2) and secondary education (-6.4 pps (95% CI: -7.0 to -4.8).

Conclusions

Overall, self-reported poor mental health was found to be associated with a greater likelihood of reporting complete tooth loss. Findings from this study underscore the need for greater integration of care delivery between behavioral health specialists and dental providers.

Chewing difficulties mediated association between edentulism and depressive symptoms among middle aged and older population

BACKGROUND

Depression is a major health condition among the aging population. Previous studies indicated that edentulism was a risk factor for depression. The link between edentulism and depression has not been fully clarified.

OBJECTIVES

This study aimed to estimate whether chewing difficulties play a mediating role in the association between edentulism and depression among middle-aged and older populations with national cross-sectional data.

METHODS

Data were obtained from the latest fourth wave of the China Health and Retirement Longitudinal Study (CHARLS). The outcome variable was set as depression, which was measured by the Center for Epidemiologic Studies Depression Scale (CES-D-10). Independent and mediated variables were separately set as self-assessed edentulism and chewing difficulties. The nearest neighbour propensity score matching (PSM) method was used to construct a matching group to balance the basic characteristics of individuals with and without edentulism with minimised bias in the estimation. Causal mediation analysis was performed to estimate the degree of contribution of chewing difficulties to the association between edentulism and depression. Several sensitivity analyses were performed to evaluate the robustness of the primary result.

RESULTS

A total of 15 853 individuals remained for analysis. After PSM, 809 individuals with edentulism and 2628 without edentulism remained for analysis. Among the matched individuals, the mean age was 66.3 ± 9.2 years, 58.5% were female, 78.8% lived in rural areas, 23.5% had edentulism, 51.1% had depressive symptoms, and 50.1% had chewing difficulties. Logistic regression results showed that a higher incidence of edentulism was associated with a higher rate of depression (OR: 1.39, 95% CI: 1.19-1.63) in the matching group. Causal mediation analysis results indicated that the average mediation effect of chewing difficulties on the association between edentulism and depression was 0.010 (95% CI: 0.005-0.015), and the average direct effect was 0.072 (95% CI: 0.036-0.11). The mediation proportion of chewing difficulties was 11.7% (95% CI: 0.079-0.21).

CONCLUSION

A higher prevalence of edentulism was associated with a higher rate of depression among middle-aged and elderly populations. Chewing difficulties moderately mediated the association between edentulism and depression. Fundamental oral function should not be neglected to improve mental health among the aging population.

Frequency of Going Outdoors and Risk of Poor Oral Health Among Older Japanese Adults: A Longitudinal Cohort From the Japan Gerontological Evaluation Study

BACKGROUND

The association between the frequency of going outdoors and the risk of poor oral health has been reported in several studies; however, the findings have been inconclusive.

METHODS

We conducted a 3-year longitudinal study of 19,972 Japanese adults aged ≥65 years who reported no poor oral condition at baseline in 2013. The respondents rated their frequency of going outdoors in three categories (≤1, 2-3, or ≥4 times/week), and the oral conditions reported in 2016 included tooth loss, chewing difficulty, swallowing difficulty, dry mouth, and composite outcomes. The associations between the frequency of going outdoors and the risk of poor oral health were examined as relative risk ratios (RRs) and 95% confidence intervals (CIs) using multivariable Poisson regression, while mediation analysis was performed to investigate indirect effects.

RESULTS

During the follow-up, 32.5% of participants developed poor oral health. In the mediation analysis, indirect effects were observed through low instrumental activities of daily living, depressive symptoms, little social network diversity, and underweight. Compared to going outdoors ≥4 times/week, the multivariable RRs of composite poor oral health conditions were 1.12 (95% CI, 1.05-1.20) for 2-3 times/week and 1.22 (95% CI, 1.07-1.39) for ≤1 time/week (P-trend < 0.001). Similar associations were observed for tooth loss, chewing difficulty, and swallowing difficulty; the corresponding RRs were 1.07 (95% CI, 0.97-1.19) and 1.36 (95% CI, 1.13-1.64) (P-trend = 0.002), 1.18 (95% CI, 1.06-1.32) and 1.30 (95% CI, 1.05-1.60) (P-trend < 0.001), and 1.15 (95% CI, 1.01-1.31) and 1.38 (95% CI, 1.08-1.77) (P-trend = 0.002), respectively.

CONCLUSION

The frequency of going outdoors was inversely associated with the risk of poor oral health through several modifiable risk factors in the older population.

Relationship between oral health and depression: data from the National Health Survey 2016-2017

OBJECTIVE

To evaluate the relationship between oral health status, self-perception of oral health, and depression.

METHODS

This cross-sectional study included 2953 individuals that were ≥ 18 years of age and participated in the Chilean National Health Survey (NHS), 2016-2017. Information on oral, dental, and mental health, and the presence or absence of depressive symptoms was collected. Secondary data analysis was carried out using STATA and included logistic regression models adjusted for sex, age, and educational level. The analyses factored in the expansion weights to estimate representative prevalences of the entire population.

RESULTS

Participants experiencing frequent dental or prosthesis-related discomfort while speaking (OR: 1.57; 95% CI: 1.01-2.43) were related with exhibiting suspected depression. Removable upper denture users were at a higher risk of exhibiting suspected (OR: 2.04; 95% CI: 1.11-3.74) than those not using them. Participants diagnosed with depression in the past 12 months had a similar number of teeth (median = 24) compared to those without depression (median = 25) (OR: 0.99; 95% CI: 0.96-1.02).

CONCLUSION

Experiencing dental or prosthesis-related difficulties in speaking is related to suspected depression or a diagnosis of depression. These findings highlight the importance of developing comprehensive healthcare approaches that consider mental health in the context of oral health.

The Dutch version of the Oral Health Assessment Tool: Translation and inter-rater reliability among community nurses

OBJECTIVES

Translating the Oral Health Assessment Tool (OHAT) into Dutch and assessing the inter-rater reliability among community nurses.

METHODS

The original version of the OHAT was translated following the five stages of the 'Guidelines for the Process of Cross-Cultural Adaptation'. After a forward and backward translation, consensus on the pre-final version was obtained in an expert panel discussion. This version was pre-tested on its comprehensibility among 31 nurses and hereafter finalized. Then, inter-rater reliability of the OHAT-NL was determined by two trained nurses during oral assessments of 37 care-dependent community-dwelling older people. Intraclass correlation coefficient (ICC) and the Cohen's kappa statistic for individual items were estimated.

RESULTS

Feedback from nurses in the pre-test did lead to minor changes of the OHAT-NL. Inter-rater reliability was good (ICC 0.79; 95% CI 0.63-0.89) on the total score. Agreement on item level ranged from fair to very good, the kappa ranged from 0.36-0.89.

CONCLUSIONS

OHAT is now available in Dutch having good inter-rater reliability among trained community nurses. Future research can further validate the OHAT-NL and develop intervention according to total OHAT-NL scores.

Depression and Differential Oral Health Status Among U.S. Adults With and Without Prior Active Duty Service in the U.S. Military, National Health and Nutrition Examination Survey 2011-2018

INTRODUCTION

Veterans suffer from lower overall well-being than non-veterans because of their unique life course. This study aims to compare the impact of depression on oral health for veteran and non-veteran populations.

MATERIALS AND METHODS

Data from 11,693 adults (18+) participating in the National Health and Nutrition Examination Survey (2011-2018) were analyzed. The outcome variables were dichotomous (at/above mean) decayed, missing, and filled teeth due to caries (DMFT), as well as the components, namely, missing teeth, filled teeth (FT), and decayed teeth (DT). The primary predictor variable combined depression screening outcome and veteran status (veteran/depressed, veteran/not depressed, non-veteran/depressed, and non-veteran/not depressed). Covariates included socioeconomic factors, demographics, wellness factors, and oral health-related habits. Associations between outcome and predictor variables were assessed with a fully adjusted logistic regression analysis.

RESULTS

Veterans, regardless of depression status, had more DMFT, FT, missing teeth, and DT compared to non-veterans. After controlling for covariates, veterans suffering from depression had higher odds of DT (1.5, 95% CI, 1.0-2.4) compared to non-veterans without depression. In general, veterans who screened negative for depression had better oral health compared to all groups, with lower odds of DT (0.7, 95% CI, 0.6-0.9) and higher odds of FT (1.4, 95% CI, 1.1-1.7) compared to non-veterans with and without depression.

CONCLUSIONS

This study found that not only veterans have higher odds of overall caries experience, but also veterans suffering from depression have higher odds of active caries compared to non-depressed veterans. Most veterans lack Veterans Health Administration dental benefits and face challenges maintaining oral health on top of medical and mental health burdens. Our results add further urgency to increasing dental care access for this vulnerable population because of the exacerbation of unmet oral health care needs attributable to the additional mental health challenges veterans face.

Association of Stressful Life Events With Oral Health Among Japanese Workers

BACKGROUND

Psychological stress can cause various mental and physical health problems. The previous results on stress and oral health are inconsistent, possibly because of the narrow stress measurements. We aimed to examine the association between a broader range of stressful life events and oral health among workers.

METHODS

This cross-sectional study analyzed anonymous individual data from a national survey in Japan. Data on stressful life events, oral health problems which are one or more of tooth pain, gum swelling/bleeding, and difficulty chewing, and covariates were obtained using a self-reported questionnaire. Covariates used included gender, age group, and disease under treatment. Logistic regression analysis was used to estimate the association between stressful life events and oral health problems. We then estimated the causal treatment effects of stress using the augmented inverse-probability weighting (AIPW) method.

RESULTS

Among the 274,881 subjects, 152,850 men (55.6%) and 122,031 women (44.4%) with a mean age of 47.0 (standard deviation, 14.4) years, 4.0% reported oral health problems, with a prevalence of 2.1% among those without any stress. The prevalence increased with stress score, reaching 15.4% for those with the maximum stress score. The adjusted odds ratio of this group compared to those without any stress was 9.2 (95% confidence interval [CI], 8.2-10.3). The estimated prevalence of oral health problems by the AIPW analysis was 2.2% (95% CI, 2.1-2.3%) for those without any stress and 14.4% (95% CI, 12.1-16.7%) for those with the maximum stress scores.

CONCLUSION

There was a clear dose-response association between stressful life events and oral health problems.

Psychological aspects of rehabilitation nutrition: A position paper by the Japanese Association of Rehabilitation Nutrition (secondary publication)

Psychological aspects of rehabilitation nutrition affect physical, cognitive, and social rehabilitation nutrition. When depression is recognized, not only pharmacotherapy and psychotherapy, but also non-pharmacological therapies such as exercise, nutrition, psychosocial, and other interventions can be expected to improve depression. Therefore, accurate diagnosis and intervention without overlooking depression is important. Psychological aspects of preventive rehabilitation nutrition is also important because depression can be partially prevented by appropriate exercise and nutritional management. Even in the absence of psychological negatives, increasing more psychological positives from a positive psychology perspective can be useful for both patients and healthcare professionals. Positive rehabilitation nutrition interventions can increase more psychological positives, such as well-being, through cognitive-behavioral therapy and mindfulness on their own, as well as through interventions on environmental factors. Consequently, physical, cognitive, and social positives are also expected to be enhanced.

Improving oral health of older adults for healthy ageing

The objective of this article is to discuss the importance of oral health in achieving healthy ageing and the role of all stakeholders in improving oral health for older adults. The World Health Organization defined healthy ageing as the process of developing and maintaining the functional ability that enables well-being in older age. It recognized healthy ageing as an important goal and the key to turn population ageing from a challenge to an opportunity. Healthy ageing has positive impacts on individual older adults, their families and societies. It enhances quality of life of older adults, strengthen family bonding of families and reduce resource demand of the societies. Maintaining oral health and function is essential in healthy ageing. Oral health affects systemic health, cognitive health and psychological health. Oral functions such as eating ensure nutritional health in older adults. Most oral diseases are preventable and oral function decline can be recovered by intervention. Unfortunately, oral diseases remain prevalent and oral function decline is being neglected in older adults. Policy makers, national dental associations, academics and healthcare professionals should collaborate to provide a patient-centred, comprehensive and integrated care to older adults. Health policy reforms are needed to reduce the global oral health inequalities in older adults. Population-wide prevention should be accessible, affordable and available to older adults. Universal oral health coverage is crucial for integration of oral health into general health care.

Improving Patient Well-Being as a Broader Perspective in Dentistry

Patient well-being encompasses the physical, mental, psychological, and social health of an individual. To adequately treat an individual and increase their quality of life, whole-person, patient-centred care needs to be utilised. This review aims to concisely summarise ways to improve patients' well-being through and in dentistry. Oral health is tied to one's quality of life through oral function, overall health, self-perception, social acceptance, and social interaction. These relationships demonstrate the importance of utilising oral health to increase patient quality of life, unify health professions in patient treatment, use preventative medicine, and empower patients about their health. To do so, the dental profession can increase the scope of practice to provide preventative health screening and education on general health, have more open communication, collaborate with other health care professionals, and have broader consultations. This will allow for better continuity of care and shift the focus of treatment to the whole person instead of a symptom. Whilst there are barriers that need to be resolved and cost feasibility requires more exploration, the potential benefit to patients is apparent.

Maternal depression in first 1000 days of life and early childhood caries prevalence at 48 months of age

OBJECTIVES

The aim of this study was to investigate the effect of maternal's depression trajectory in the first 1000 days of the child's life on the prevalence of early childhood dental caries (ECC), in a birth cohort.

MATERIALS AND METHODS

All infants born in Pelotas in 2015 were identified, and the mothers were invited to participate in the cohort. A total of 3645 children were included in the study. The outcome was ECC at 48 months of age assessed according to ICDAS. Maternal depression was collected using Edinburgh Postnatal Depression Scale (EPDS) antenatally, at 3, 12, and 24 months of age. Maternal depressive symptom trajectory variables were created using group-based trajectory models and adopting two cutoff points. Poisson regression model with robust variance was used to identify the total effect of maternal depressive symptom trajectories on ECC, adjusting by confounders.

RESULTS

A total of 29.2% of the mothers presented a high trajectory for screening of depression, and 18.8% presented a high trajectory of depression diagnosis. The prevalence of ECC was 26.7%. After adjusted analysis, maternal depression trajectories (screening and diagnosis) from pregnancy to 24 months increased the risk for ECC at 48 months of age (RR = 1.14; 95% CI 1.02-1.28 and RR = 1.19; 95% CI 1.05-1.35).

CONCLUSIONS

Children from mothers with high depression trajectory had higher risk of having dental caries at 48 months compared to children from mothers with low depression trajectory.

CLINICAL RELEVANCE

Strategies of early detection and treatment of maternal mental disorders during the Golden Period should be considered of high priority in health services since it could impact positively in children's life.

Association between periodontitis and depression severity - A cross-sectional study of the older population in Hamburg

The aim of the current study is to investigate the association between periodontitis (exposure variable) and depression severity (outcome variable) in an older German population. We evaluated data from 6,209 participants (median age 62 years) of the Hamburg City Health Study (HCHS). The HCHS is a prospective cohort study and is registered at ClinicalTrial.gov (NCT03934957). Depression severity were assessed with the 9-item Patient Health Questionnaire (PHQ-9). Periodontal examination included probing depth, gingival recession, plaque index, and bleeding on probing. Descriptive analyses were stratified by periodontitis severity. Multiple linear regression models were adjusted for age, sex, diabetes, education, smoking, and antidepressant medication. Linear regression analyses revealed a significant association between log-transformed depression severity and periodontitis when including the interaction term for periodontitis * age, even after adjusting for age, sex, diabetes, education, smoking and antidepressant medication. We identified a significant association between severe periodontitis and elevated depression severity, which interacts with age. Additionally, we performed a linear regression model for biomarker analyses, which revealed significant associations between depression severity and severe periodontitis with log-transformed inflammatory biomarkers interleukin 6 (IL-6) and high-sensitivity C-reactive protein (hsCRP). In order to identify new therapeutic strategies for patients with depression and periodontal disease, future prospective studies are needed to assess the physiological and psychosocial mechanisms behind this relationship and the causal directionality.

Health topics emerged from brief-motivational interviewing: A randomized clinical trial

OBJECTIVE

The goal of this study was to analyse transcription of audio recordings to determine health topics that emerged from brief-motivational interviewing (MI) compared to traditional oral hygiene instructions (OHI).

METHODS

Fifty-eight periodontal maintenance patients were randomized to a brief-MI or traditional OHI group for a longitudinal 1-year clinical trial. Both groups received four patient education sessions per their assigned group. Audio recordings were transcribed and coded. The overarching themes and subthemes emerged were quantified and reported as the number of instances per participant. Global scores and behavioural counts were compared across baseline, 4, 8, and 12-month research visits using mixed-effect models.

RESULTS

Of the six overarching themes, the brief-MI group evoked more topics toward total health. Oral home care behaviours (15 vs. 10.2) and oral diseases/conditions (3.3 vs. 1.9) were discussed more in the brief-MI group compared to the traditional OHI group. This positive outcome for the average number of times a health topic was discussed in the brief-MI group compared to the traditional OHI group continued for the remaining major themes: lifestyle behaviours (1.0 vs. 0.4), nutrition (2.6 vs. 0.8), emotional/mental health (1.8 vs. 0.8) and general health (1.2 vs. 0.4).

CONCLUSION

This study identified that brief-MI was a more successful communication approach to increase discussions of oral home care behaviours, oral diseases/conditions, lifestyle behaviours, nutrition, emotional/mental health and general health compared to traditional OHI in individuals with periodontitis.

Relationships among oral hygiene behavior, toothache, and depressive symptoms in Chinese older adults

OBJECTIVES

The study aims to investigate the relationships among oral hygiene behavior, toothache, and depression among Chinese older adults.

METHODS

We used data came from the 2018 wave of Chinese Longitudinal Healthy Longevity Survey (CLHLS). The Center for Epidemiologic Studies Depression Scale was used to evaluate depression. Binary logistic regression was performed to analyze the relationships among oral hygiene behavior, toothache, and depression.

RESULTS

A total of 12,172 older adults were included in the study, of whom 27.2% had depression. Compared with those who did not brush their teeth daily, those who brushed their teeth at least once daily exhibited lower odds of having depressive symptoms (odds ratio [OR] = 0.86, 95% confidence interval [CI] = 0.77-0.97 versus OR = 0.81, 95% CI = 0.71-0.93). Compared with those who did not have toothache, those who had toothache over the past 6 months exhibited higher odds of having depression (OR = 1.49, 95% CI = 1.33-1.68). Living arrangement had a significant effect on the correlation between toothache and depression (p = 0.049), who lived alone and had toothache exhibited higher odds of having depressive symptoms.

CONCLUSIONS

Oral hygiene behavior and toothache are associated with depression. Taking effective measures to maintain a daily toothbrushing pattern and reduce the occurrence of toothache may mitigate the risk of depression among older adults, especially among those living alone.

CLINICAL RELEVANCE

The present study reports that the potential relationship between different oral hygiene behavior, toothache, and depressive symptoms.

Association between number of remaining teeth and incident depression in a rural Chilean cohort

OBJECTIVES

Previous studies have established an association between tooth loss and depression. However, longitudinal evidence is scarce and needs to be verified in other populations. The aim of this study was to examine the longitudinal association between the number of remaining teeth and incident depression at 2- and 4-years follow-up in individuals enrolled in the Maule cohort (MAUCO) in Chile.

METHODS

This prospective study used the information of individuals, aged 38 to 74 years, excluding those with depression at baseline. The number of remaining teeth at baseline was determined in four groups: "20 or more teeth", "10 to 19 teeth", "1 to 9 teeth" and "no natural teeth". Depression was measured through the PHQ-9. Logistic regression was performed to calculate the odds ratios (OR) for incidence depression at both periods of follow-ups, adjusting for age, sex, educational attainment, diabetes mellitus II, and stressful events at follow-up. Also, we performed adjusted multinomial logistic models to analysis the association between the number of remaining teeth and depression severity.

RESULTS

In total individuals (n = 3335 at follow 1, n = 2461 at follow 2), all groups have ORs for incident depression above 1 considering 20 or more teeth as reference. In men, those with 10-19 teeth have 2.44 times higher odds of incident depression than those with 20 or more teeth (OR 2.44, CI 95% 1.33-4.50). Edentulous subjects at 4 years follow-up had 2.24 times higher odds of depression than those with more than 20 teeth (OR 2.24 CI 95%1.35-3.72). In women, the ORs (CI 95%) of incident depression were 2.56 (1.50-4.39), 1.56 (1.02-2.40) and 1.27 (0.90-1.81) for "none", "1-9", "10-19" respectively in comparison to the reference group. In edentulous individuals at baseline, the odds for each of the comparisons "mild vs no", "moderate vs no", "moderately severe vs no" and "severe vs no" were above 1, at both follow-ups.

CONCLUSION

Individuals with less than 20 teeth in the mouth could had higher odds of incident depression at 2- and 4-years follow-up, with differences between men and women. Also, in our study, edentulism was associated with increased odds of incident depression at 4-years follow-up in women, and with higher levels of severity of depressive symptoms.

Association of oral status with frailty among older adults in nursing homes: a cross-sectional study

BACKGROUND

The oral status of an individual is a vital aspect of their overall health. However, older adults in nursing homes have a higher prevalence of frailty and poor oral health, particularly in the context of global aging. The objective of this study is to explore the association between oral status and frailty among older adults residing in nursing homes.

METHODS

The study involved 1280 individuals aged 60 and above from nursing homes in Hunan province, China. A simple frailty questionnaire (FRAIL scale) was used to evaluate physical frailty, while the Oral Health Assessment Tool was used to assess oral status. The frequency of tooth brushing was classified as never, once a day, and twice or more a day. The traditional multinomial logistic regression model was used to analyze the association between oral status and frailty. Adjusted odds ratios (OR) and 95% confidence intervals (CI) were estimated while controlling for other confounding factors.

RESULTS

The study found that the prevalence of frailty among older adults living in nursing homes was 53.6%, while the prevalence of pre-frailty was 36.3%. After controlling for all potential confounding factors, mouth changes requiring monitoring (OR = 2.10, 95% CI = 1.34-3.31, P = 0.001) and unhealthy mouth (OR = 2.55, 95% CI = 1.61-4.06, P < 0.001) were significantly associated with increased odds of frailty among older adults in nursing homes. Similarly, both mouth changes requiring monitoring (OR = 1.91, 95% CI = 1.20-3.06, P = 0.007) and unhealthy mouth (OR = 2.24, 95% CI = 1.39-3.63, P = 0.001) were significantly associated with a higher prevalence of pre-frailty. Moreover, brushing teeth twice or more times a day was found to be significantly associated with a lower prevalence of both pre-frailty (OR = 0.55, 95% CI = 0.34-0.88, P = 0.013) and frailty (OR = 0.50, 95% CI = 0.32-0.78, P = 0.002). Conversely, never brushing teeth was significantly associated with higher odds of pre-frailty (OR = 1.82, 95% CI = 1.09-3.05, P = 0.022) and frailty (OR = 1.74, 95% CI = 1.06-2.88, P = 0.030).

CONCLUSIONS

Mouth changes that require monitoring and unhealthy mouth increase the likelihood of frailty among older adults in nursing homes. On the other hand, those who brush their teeth frequently have a lower prevalence of frailty. However, further research is needed to determine whether improving the oral status of older adults can change their level of frailty.

[Association between oral health and cognitive decline in older Chileans]

OBJECTIVE

To identify the association between oral health and suspected cognitive impairment in older adults in Chile.

METHOD

Cross-sectional study including 1826 people ≥60 years who participated in the National Health Survey of Chile, 2016-2017. Oral health was evaluated by the number of teeth, presence of caries, use of dental prostheses, self-reported oral health, and pain and/or discomfort in the oral cavity. Cognitive impairment was assessed using the Mini-Mental State Examination (MMSE). The association was evaluated by logistic and linear regression, adjusted for sociodemographic and lifestyle variables.

RESULTS

Compared with people without suspicion of cognitive impairment, people with suspected impairment had five fewer teeth (13.4 vs. 8.5 teeth), a much higher difference in women than in men, and a higher frequency of oral pain. Edentulism and fewer teeth were associated with a higher likelihood of suspected cognitive impairment, associations that were not maintained in adjusted models. Oral pain was associated with a higher likelihood of suspected impairment even in the most adjusted model (odds ratio: 1.99; 95% confidence interval [95%CI]: 1.09-3.63). In linear models, an increase of 2% (95%CI: 0.01-0.05) in the MMSE score was observed for each additional tooth.

CONCLUSIONS

Poor oral health, particularly tooth loss and the presence of pain, was associated with cognitive impairment in older adults in Chile.

The association between social isolation and oral health of community-dwelling older adults-A systematic review

AIM

Social isolation and oral health problems commonly exist in older populations and can influence each other. However, evidence on this bidirectional correlation is scarce. This systematic review aimed to provide a comprehensive overview of literature in which social isolation and oral health were associated with each other separately.

METHODS

Electronic searches were performed through six databases. Original cross-sectional and longitudinal prospective studies that evaluated the associations between social isolation and oral health as either exposure or outcome were included.

RESULTS

In total, 282 articles were retrieved. Of these, 10 cross-sectional studies and one longitudinal study were included in the analysis. The level of evidence reported was generally moderate to strong. Most studies found that both stronger objective and perceived social isolation were associated with worse oral health in both directions. The frequency of meeting friends had an inconsistent association with oral health.

CONCLUSIONS

The results of our systematic review showed a bidirectional association between social isolation and oral health in independent community-dwelling older adults. Both objective and perceived social isolation are associated with oral health. As objective social isolation indicators, quality of social connectedness appears to play a more important role in the association with oral health.

Depression and oral health-related quality of life: A longitudinal study

Objectives

Geriatric oral health-related quality of life is a relatively new but rapidly growing concept as it is directly related to the general wellbeing and self-esteem of older adults. This study assessed the impact of worsening depression symptoms on oral health-related quality of life using representative nationwide data of Korean older adults.

Methods

This study comprised a longitudinal sample of older adults aged ≥60 from the Korean Longitudinal Study of Aging (2016-2020). After applying the exclusion criteria, 3,286 participants were included in the study. Depression status was determined through the biennial assessment of the short-form Center for Epidemiologic Studies Depression Scale (CESD-10); oral health was measured using the Geriatric Oral Health Assessment Index (GOHAI). We employed the lagged general estimating equations to assess the temporal effect of the CESD-10 score change on the GOHAI score.

Results

A decrease in CESD-10 score over a 2-year period was significantly associated with a decrease in GOHAI score in men and women: β = -1.810 and β = -1.278, respectively (p-values < 0.0001). Furthermore, compared to the same or improved CESD-10 score, worsening of the score on 1-2 points detected the β = -1.793 in men and β = -1.356 in women, and worsening on ≥3 points: β = -3.614 in men and β = -2.533 in women.

Conclusions

This study found that depression exacerbation is negatively associated with oral health-related quality of life in later life. Further, a more significant worsening of depression symptoms was correlated with lower scores for oral health-related quality of life in our study population.

Validation of depression determinants in caregivers of dementia patients with machine learning algorithms and statistical model

Introduction

Due to its increasing prevalence, dementia is currently one of the most extensively studied health issues. Although it represents a comparatively less-addressed issue, the caregiving burden for dementia patients is likewise receiving attention.

Methods

To identify determinants of depression in dementia caregivers, using Community Health Survey (CHS) data collected by the Korea Disease Control and Prevention Agency (KDCA). By setting "dementia caregiver's status of residence with patient" as a standard variable, we selected corresponding CHS data from 2011 to 2019. After refining the data, we split dementia caregiver and general population groups among the dataset (n = 15,708; common variables = 34). We then applied three machine learning algorithms: Extreme Gradient Boosting (XGBoost), Logistic Regression (LR), and Support Vector Classifier (SVC). Subsequently, we selected XGBoost, as it exhibited superior performance to the other algorithms. On the feature importance of XGBoost, we performed a multivariate hierarchical regression analysis to validate the depression causes experienced in each group. We validated the results of the statistical model analysis by performing Welch's t-test on the main determinants exhibited within each group.

Results

By verifying the results from machine learning via statistical model analysis, we found "sex" to highly impact depression in dementia caregivers, whereas "status of economic activities" is significantly associated with depression in the general population.

Discussion

The evident difference in causes of depression between the two groups may serve as a basis for policy development to improve the mental health of dementia caregivers.

Dental visits and depression mediating the association of socioeconomic status with oral health behaviors

Determinants of oral diseases include behaviors, which in turn are influenced by a series of social determinants such as psychosocial aspects and dental care services. Therefore, the aim of this study was to investigate whether depressive symptoms and use of dental care services mediate the relationship between socioeconomic status (SES) and oral health behaviors. This was a cross-sectional study that analyzed data from participants in the 2019 National Health Survey (PNS) (n = 88,531). The eligibility criteria were individuals who were 18 years and older and exclusion criterion was living in households located in special or sparsely populated census tracts. Structural equation modeling (SEM) was used to test direct and indirect pathways from a latent variable for SES to oral health through depressive symptoms (assessed through the "Patient Health Questionnaire-9") and use of dental care services. The maximum likelihood estimator for complex samples with the robust standard error was used. The final model presented an adequate fit: RMESA of 0.008, CFI of 0.998, and SMRM of 0.005. The results showed that higher SES was directly associated with better oral health-related behaviors [standardized coefficient (SC): 0.428; p < 0.01] and indirectly through depressive symptoms [(SC): 0.002; p < 0.01] and dental care services [(SC): 0.089; p < 0.01]. The total effect of SES on oral health-related behaviors was equal to [(SC: 0.519 (p < 0.01)]. In conclusion, the findings suggest that high socioeconomic status, mediated by depressive symptoms and dental care services, has a positive effect on oral health.

Oral health and mental health in healthy adults, a topic of primary prevention and health care, empirical results from two online studies

Oral health is an important, yet often neglected aspect of health and well-being. Among geriatric populations, oral diseases, poor oral health, and reduced oral hygiene behavior are major comorbid factors of geriatric diseases such as dementia, cardiovascular diseases, or mental health conditions. However, little is known so far about the relationships between oral health and mental health in the younger adult population, who is yet not suffering from any disorder. In the present manuscript the results of two online studies, online study 1, n = 133, all-female sample and online study 2: n = 29, mixed gender sample, are reported that investigate the relationship between self-reported oral health impairments and preclinical symptoms of mental disorders including self-reported symptoms associated with depression or eating disorders as well as self-reported perceived stress and behavior change related to the COVID-19 pandemic. The results of both studies support links between self-reported oral health impairments, self-reported depressive symptoms (including anxiety and current affect) and symptoms related to eating disorders (such as bulimic behavior, body dissatisfaction or drive for thinness) among young adults and suggest that perceived stress may contribute to both, impaired oral health and impaired mental health in young adults (women and men).

Moderating effects of resilience and self-esteem on associations between self-reported oral health problems, quality of oral health, and mental health among adolescents and adults in Nigeria

BACKGROUND

There is an intersection between oral and mental health though the studies on these intersections are few. This study investigated associations between self-reported oral health problems, quality of oral health, and depression and general anxiety among adolescents and adults in Nigeria; and analysed the moderating effects of resilience and self-esteem on these associations.

METHODS

In this secondary analysis, data were extracted from the database of an online survey conducted among participants 13 years and older and living in Nigeria about their self-reported psychological wellbeing. The data was collected between September and October 2020. Dependent variables were self-reported presence of oral health problems (yes/no) and self-reported quality of oral health (using a five-item scale ranging from "very good" to "very poor"). Independent variables were depressive and anxiety symptoms. Moderating factors evaluated were resilience and self-esteem. Multivariable logistic regression analysis was used to determine the associations between the dependent and independent variables after adjusting for confounders (age, sex, employment status and educational status). A path analysis was conducted to determine the moderating effects of self-esteem and resilience on associations between dependent and independent variables.

RESULTS

We extracted data for 2,757 adolescents and adults aged 13 to 62 years, of which 2,062 (74.8%) reported having oral health problems and 925 (33.6%) reported poor quality of oral health. Higher levels of depressive symptoms were significantly associated with higher odds of oral health problems (AOR: 1.07; 95% CI: 1.04-1.10; p<0.001). Higher levels of depressive symptoms (AOR: 1.05; 95% CI: 1.03-1.07; p<0.001), and higher levels of anxiety symptoms (AOR: 1.07; 95% CI: 1.04-1.11; p<0.001) were significantly associated with poor quality of oral health. Resilience significantly moderated the association between anxiety symptoms and oral health problems (AOR = -0.004; 95% CI: -0.006 --0.001; p = 0.002).

CONCLUSION

Depression may be a risk indicator for self-reported oral health problems, while depression and anxiety appear to be risk indicators for self-reported poor quality of oral health. These factors could be included as confounders in future studies on oral health problems and quality of oral health among adolescents and adults in Nigeria.

Poor mental health days is associated with higher odds of poor oral health outcomes in the BRFSS 2020

Background

To test the hypothesis that among individuals in the 2020 Behavioral Risk Factor Surveillance System (BRFSS) cross-sectional anonymous health survey in the United States (US), after controlling for confounding, an increasing number of poor mental health (MH) days in the past month is associated with increasing odds of delayed oral health (OH) care utilization and poorer OH outcomes.

Methods

Adjusted logistic regression models were developed with poor MH days as the exposure to examine the association with two dependent variables (DVs): Most recent dental visit longer than one year ago (yes/no), and having lost 6 or more teeth (yes/no).

Results

Approximately one third (32%) reported most recent dental visit more than one year ago, and 17% had lost 6 or more teeth. Those in the second quartile of poor MH days had 11% higher odds of delayed dental visit, and those in the highest quartile had 26% higher odds, compared to the reference group. For having lost 6 or more teeth, compared to the reference group, those in the third quartile had 8% higher odds and those in the fourth quartile had 18% higher odds.

Conclusions

Poor MH days is independently associated with odds of poor OH utilization and OH in the US above and beyond diagnosed mental and physical conditions. Policymakers in the US should expand health insurance plans to include dental insurance, and should increase access to MH care, especially for the aging population, and those with chronic conditions.

Oral health-related multiple outcomes of holistic health in elderly individuals: An umbrella review of systematic reviews and meta-analyses

Background and aims

Along with an aging population, exploring the impact of oral health on holistic health and determining exact outcomes in elderly individuals are important in both scientific research and clinical practice. Significant increase in the number of systematic reviews shows that oral health can directly or indirectly affect the overall health of elderly people physically, mentally and socially. To systematically collate, appraise, and synthesize the current evidence, we carried out an umbrella review of the impacts of oral health on holistic health in elderly individuals.

Methods

A systematic reviews and meta-analyses search was performed in the major databases PubMed, MEDLINE, Web of Science and the Cochrane Library from inception to February 1, 2022, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The JBI (Joanna Briggs Institute) Critical Appraisal Checklist for Systematic Reviews and Research Syntheses was referred to assess methodological quality, and the GRADE (Grading of Recommendations, assessment, Development, and Evaluation working group classification) was used to assess the quality of evidence for each outcome included in the umbrella review.

Results

Out of 1,067 records, a total of 35 systematic reviews were included. Respiratory diseases, malnutrition, age-related oral changes, frailty, cognitive impairment, depression and poor quality of life were identified as seven key outcomes that affect the physical, mental and social health of elderly individuals. Meanwhile, three intervention measures of oral health were summarized as (i) more rigorous and universal scales, (ii) dental cleaning and denture installation, and (iii) improving self-awareness regarding oral care.

Conclusions

Evidence showed that oral health can significantly affect holistic health, and the diverse oral diseases directly lead to multiple health outcomes in elderly individuals. Clear high-quality evidence revealed that oral health is strongly associated with seven health outcomes covering physical, mental, and social levels, which directly corresponds to holistic health, and impacts the quality of life of elderly individuals. Such the results remind the importance of oral care in public health, and further studies need to be conducted to verity more specific association between oral health and other chronic diseases.

Sociodemographic Changes and Oral Health Inequities: Dental Workforce Considerations

BACKGROUND

By midcentury, the US population will be remarkably more racially and ethnically diverse, with a dramatic increase in the proportion of older adults. This report addresses ongoing oral health disparities and inequitable access to care related to these changes, with emphasis on implications for the workforce, taking note of effects of the COVID-19 pandemic.

RELEVANT CONSIDERATIONS

Considering that social determinants shape health behaviors, reflection on the most effective type of dental workforce should take into account population characteristics and the relationship of oral health with overall health and general well-being. The dental workforce composition will need to mirror changing demographics, and effective dental health teams will be characterized by cultural competence, humility, readiness, and capacity to adapt to changes. In addition, the influence of social histories and the pandemic on health and dental care utilization is important. Equally important are the inclusion of oral health literacy in treatment planning and disease prevention, as well as oral health-related quality of life in considering outcomes of care. Providing patient-centered care for a diverse population requires tailored treatment modalities, as well as intra- and interprofessional approaches. In this way, the whole person can be cared for, including those with special health care needs, whether related to chronic disease, mental health conditions, or behavioral, physical, and social differences.

CONCLUSIONS

Changing demographics will affect the delivery of oral health care, including who can best provide care and how, what the needs are, and in what ways prevention and treatment can most effectively be accomplished. The education of dentists must address unmet population needs, including for those with special health care concerns and older adults. These population groups are influenced by a variety of social determinants, and provision of services may need to occur in alternative care delivery settings. Identifying and addressing the needs of every patient within this broad array of new requirements will challenge dental professionals to redefine what it means to be a health care practitioner.

KNOWLEDGE TRANSFER STATEMENT

This article describes how sociodemographic changes in the United States will challenge the dental workforce in new ways and points to research and practice needs to address these challenges. Oral health disparities and the changing oral health care needs of patients from diverse and underserved groups are discussed, with a focus on the implications for delivery of care and policies that are needed to improve oral health outcomes for all.

Elements of Integrated Behavioral Health Associated with Primary Care Provider Confidence in Managing Depression at Community Health Centers

BACKGROUND

Depression is most often treated by primary care providers (PCPs), but low self-efficacy in caring for depression may impede adequate management. We aimed to identify which elements of integrated behavioral health (BH) were associated with greater confidence among PCPs in identifying and managing depression.

DESIGN

Mailed cross-sectional surveys in 2016.

PARTICIPANTS

BH leaders and PCPs caring for adult patients at community health centers (CHCs) in 10 midwestern states.

MAIN MEASURES

Survey items asked about depression screening, systems to support care, availability and integration of BH, and PCP attitudes and experiences. PCPs rated their confidence in diagnosing, assessing severity, providing counseling, and prescribing medication for depression on a 5-point scale. An overall confidence score was calculated (range 4 (low) to 20 (high)). Multilevel linear mixed models were used to identify factors associated with confidence.

KEY RESULTS

Response rates were 60% (N=77/128) and 52% (N=538/1039) for BH leaders and PCPs, respectively. Mean overall confidence score was 15.25±2.36. Confidence was higher among PCPs who were satisfied with the accuracy of depression screening (0.38, p=0.01), worked at CHCs with depression tracking systems (0.48, p=0.045), had access to patients' BH treatment plans (1.59, p=0.002), and cared for more patients with depression (0.29, p=0.003). PCPs who reported their CHC had a sufficient number of psychiatrists were more confident diagnosing depression (0.20, p=0.02) and assessing severity (0.24, p=0.03). Confidence in prescribing was lower at CHCs with more patients living below poverty (-0.66, p<0.001). Confidence in diagnosing was lower at CHCs with more Black/African American patients (-0.20, p=0.03).

CONCLUSIONS

PCPs who had access to BH treatment plans, a system for tracking patients with depression, screening protocols, and a sufficient number of psychiatrists were more confident identifying and managing depression. Efforts are needed to address disparities and support PCPs caring for vulnerable patients with depression.

Relationship between diet quality and depression among Iranian older adults in Tehran

Background

Depression is one of the prevalent mental disorders that is common in older ages. Evidence suggests that dietary intake status may potentially be associated with depression. However, this association has not been well studied in older adults, and the nature of the association remains unclear. This study aimed to investigate the association between diet quality and depression in free-living older adults living in Tehran city.

Methods

This cross-sectional study was conducted on 583 older adults (279 men and 304 women) aged 60 to 80 years living in Tehran city, selected by the systematic cluster sampling method. Individuals' dietary intake was determined by two non-consecutive 24-h dietary recalls, and diet quality was assessed calculating score of Healthy Eating Index-2015 (HEI-2015). The validated short form of the Geriatric Depression Scale (GDS-11) was used to assess depression status. A logistic regression model was used to assess the chance of depression across tertiles of HEI-2015 score.

Results

The point prevalence of depression was 22.5%, which was significantly higher in women (91 (69.5%) women vs. 40 (30.5%) men). A higher percentage of seniors at the higher tertile of HEI score were women, belonged to Fars ethnicity and had a higher score of activity of daily living (ADL). After adjustment for all potential confounders, the trend of depression chance was significantly decreased in those with higher HEI-2015 scores (p-for trend < 0.05).

Conclusion

Higher quality of diet was associated with a lower possibility of depression in the studied participants. Further studies are required to investigate the possible causal relationship.

Prevalence of dental disorders among people with mental illness: An umbrella review

OBJECTIVE

Psychiatric patients have increased rates of comorbid physical illness. There are less data on dental disease, especially decay, despite risk factors including lifestyle and psychotropic side effects such as xerostomia. We therefore undertook an umbrella review of all meta-analyses on the association between mental illness and oral health.

METHODS

We searched PubMed, MEDLINE, PsycINFO, the Cochrane Central Register of Controlled Trials, Embase and CINAHL. Articles were independently assessed. Outcomes were caries, periodontal disease, erosion, and partial or total tooth loss (edentulism), measured where possible with standardised measures such as the mean number of decayed, missing and filled teeth or surfaces. Quality was assessed in line with National Institutes of Health guidelines.

RESULTS

We identified 11 meta-analyses. The most information and strongest association was between dental decay and severe mental illness or substance use, as well as erosion and eating disorders. Depressive, anxiety and eating disorders were also associated with caries, but the datasets were small. People with severe mental illness had nearly three times the odds of having lost all their teeth than the general community (odds ratio = 2.81, 95% confidence interval = [1.73, 4.57]) and those with depression between 1.17 and 1.32. Findings for periodontal disease were more equivocal, possibly because of study heterogeneity.

CONCLUSION

Mental health clinicians should screen for oral diseases when treating those with mental illness and facilitate referral to affordable dental clinics when indicated. Prevention should be a priority, including the promotion of dental care, as well as the management of xerostomia when psychopharmacologic agents are prescribed.

No bidirectional relationship between depression and periodontitis: A genetic correlation and Mendelian randomization study

Background

Observational and in-vivo research suggested a bidirectional relationship between depression and periodontitis. We estimated the genetic correlation and examined directionality of causation.

Methods

The study used summary statistics from published genome wide association studies, with sample sizes ranging from 45,563 to 797,563 individuals of European ancestry. We performed linkage disequilibrium score regression (LDSC) to estimate global correlation and used Heritability Estimation from Summary Statistics (ρ-HESS) to further examine local genetic correlation. Latent Heritable Confounder Mendelian randomization (LHC-MR), Causal Analysis using Summary Effect estimates (CAUSE), and conventional MR approaches assessed bidirectional causation.

Results

LDSC observed only weak genetic correlation (r_g = 0.06, P-Value = 0.619) between depression and periodontitis. Analysis of local genetic correlation using ρ-HESS did not reveal loci of significant local genetic covariance. LHC-MR, CAUSE and conventional MR models provided no support for bidirectional causation between depression and periodontitis, with odds ratios ranging from 1.00 to 1.06 in either direction.

Conclusions

Results do not support shared heritability or a causal connection between depression and periodontitis.

Oral health problems and risk of incident disability in two studies of older adults in the United Kingdom and the United States

BACKGROUND

Preventing oral health problems can be crucial for maintaining physical independence in older adults. We aimed to examine the associations of a range of oral health problems with incidence of disability in older adults.

METHODS

We used prospective data from the British Regional Health Study (BRHS) (N = 2147, 71-92 years), and the Health, Aging and Body Composition (HABC) study (USA) (N = 3075, 71-80 years). Oral health measures included tooth loss, periodontal disease, self-rated oral health, and self-reported dry mouth. Participants were followed for onset of disability over a follow-up period of 3 years. Onset of disability was assessed through new cases of mobility limitations, activities of daily living (ADL), and instrumental activities of daily living (IADL). Logistic regression was performed to calculate the odds of incident disability.

RESULTS

In the BRHS, tooth loss was associated with greater odds of mobility limitations and ADL difficulties. Periodontal disease was associated with greater incidence of mobility limitations. Self-report of ≥3 dry mouth symptoms was associated with increased odds of incident mobility limitations and ADL difficulties (OR = 2.08, 95% CI 1.27-3.42; OR = 1.73, 95% CI 1.03-2.90). Fair/poor self-rated oral health was associated with greater incidence of IADL difficulties. In the HABC study, complete tooth loss was associated with greater incidence of mobility limitations (OR = 1.86, 95% CI 1.13-3.06), and fair/poor self-rated oral health was associated with increased odds of incident ADL difficulties (OR = 1.42, 95% CI 1.04-1.94).

CONCLUSIONS

Oral health problems in older adults, particularly tooth loss, self-reported dry mouth and self-rated oral health were associated with greater incidence of disability. Poor oral health plays a potentially important role in the development of disability in older populations, which in turn is an essential part of quality of life and healthy aging.

Oral Health and Frailty in Community-Dwelling Older Adults in the Northern Netherlands: A Cross-Sectional Study

The aim of this study was to explore the association between oral health and frailty in community-dwelling Dutch adults aged 55 years and older. Included were 170 participants (n = 95 female [56%]; median age 64 years [IQR: 59−69 years]). Frailty was assessed by the Groningen Frailty Indicator. Oral health was assessed by the Oral Health Impact Profile-14-NL (OHIP-NL14). OHIP-NL14 item scores were analyzed for differences between frail and non-frail participants. Univariate and multivariate logistic regression analyses were performed to assess the association between oral health and presence of frailty. The multivariate analysis included age, gender, and depressive symptoms as co-variables. After adjustment, 1 point increase on the OHIP-NL14 scale was associated with 21% higher odds of being frail (p = 0.000). In addition, significantly more frail participants reported presence of problems on each OHIP-NL14 item, compared to non-frail participants (p < 0.003). Contrast in prevalence of different oral health problems between frail and non-frail was most prominent in ‘younger’ older adults aged 55−64 years. In conclusion: decreased oral health was associated with frailty in older adults aged ≥55 years. Since oral health problems are not included in most frailty assessments, tackling oral health problems may not be sufficiently emphasized in frailty policies.

Pathways of socioeconomic inequalities in self-perceived oral health

Although there is a large body of evidence of the influence of social determinants on oral health, information on the mechanisms by which these determinants operate is poorly documented. Therefore, we aimed to investigate the pathways through which socioeconomic inequalities may influence self-perceived oral health (SPOH) in Brazilian adults. This cross-sectional study used data from the National Health Survey (NHS) of 2019, with a representative sample of adults aged 18 to 59 years (n = 65,803). The outcome was SPOH, assessed by a global self-item. Structural equation modeling was used to test direct and indirect pathways connecting a latent variable for socioeconomic position (SEP) to SPOH via psychosocial, behavioral, and biological factors. Higher SEP was directly associated with better SPOH [standardized coefficient (SC) = 0.069; p < 0.01)] fewer depressive symptoms (SC = -0.059; p < 0.01), fewer missing teeth (SC = 0.131; p < 0.01), and more healthy behaviors (SC = 0.643; p < 0.01). Fewer depressive symptoms (SC = -0.141; p < 0.01), more healthy behaviors (SC = 0.242; p < 0.01), and fewer missing teeth (SC = 0.058; p < 0.01) were directly associated with good SPOH. Among specific indirect effects of SEP on SPOH, the behavioral pathway was the one that best explained this association (SC = 0.155). Socioeconomic inequities in SPOH are mediate by psychosocial, behavioral, and biological factors. This has implications for positioning health strategies in the social context in which people live, to facilitate healthy choices and promote good oral health.

A study of the association between psychiatric symptoms and oral health outcomes in a population-based birth cohort at 30-year-old follow-up

OBJECTIVE

Most studies of the association between psychiatric disorders and poor oral health have been conducted in clinical settings. Where available, data from community surveys have generally been cross-sectional or considered anxiety and depression as a consequence of poor oral health, not the other way round. This study therefore used a birth cohort to assess the association of mental health, measured both cross-sectionally and longitudinally, and oral health at 30-year follow-up.

METHODS

There were 2456 adults with data on dental outcomes and oral health care at 30-year follow-up. Psychiatric morbidity was measured at both 21- and 30-year follow-up using standardised instruments including the Centre for Epidemiological Studies-Depression (CES-D) scale and Composite International Diagnostic Interview (CIDI).

RESULTS

At follow-up, 850 participants (34.6%) had undergone a dental extraction for infection or decay, and 810 had experienced significant dental pain over their lifetime. One third had not visited a dental clinic in the previous two years and 40% failed to brush their teeth at least twice daily. On adjusted analyses, dental extraction and pain were significantly associated with psychiatric morbidity cross-sectionally at 30-year follow-up and also longitudinally when psychiatric symptoms were present at both 21 and 30 years old. Several cross-sectional measures of psychiatric morbidity were also associated with frequency of tooth brushing. There were no associations with dental clinic visits.

CONCLUSIONS

The study demonstrates there are associations between oral and mental health, which are not limited to clinical settings, but were observed at a population level.

Effect of Morbidities, Depression, Anxiety, and Stress on Oral Health-Related Quality of Life among Migrant Elderly Following Children in Weifang, China

This study explored the relationship between depression, anxiety, stress, morbidity, and oral health-related quality of life (OHRQoL) in the migrant elderly following children (MEFC) in Weifang, China. A total of 613 MEFC were selected using multistage cluster random sampling. The GOHAI scale was used to evaluate oral health-related quality of life. The DASS-21 scale was used to assess levels of depression, anxiety, and stress. Univariate analysis and binary logistic regression were used to analyze the correlation between these indicators and oral health-related quality of life, of which 43.9% were classified as having poor oral health. Logistic regression analysis showed that the MEFC who were of older age (OR = 0.965, p = 0.039), with hypertension (OR = 0.567, p = 0.004), with gastroenteropathy (OR = 0.263, p = 0.007), had received an outpatient service in the past year (OR = 0.669, p = 0.048), were depressed (OR = 0.338, p = 0.012), and anxious (OR = 0.414, p = 0.026) were less likely to report good oral health status. On the other hand, the MEFC with a high school education or above (OR = 1.872, p = 0.020) were more likely to report good oral health than those with primary school education and below. In conclusion, with regard to depression, anxiety, and stress: the results indicated that the fewer morbidities, the lower the level of depression and anxiety and the better the OHRQoL of MEFC. Targeted measures for government, communities, and family members were given to improve the OHRQoL of MEFC.

Impact of the COVID-19 pandemic on oral health and psychosocial factors

The objective of this study was to investigate oral health-related quality of life (OHRQoL) in times of the COVID-19 pandemic and to examine a possible association to psychosocial factors like psychological stress and symptoms of depression and anxiety disorders. Secondary research questions were whether people changed oral hygiene regimens during the COVID-19 pandemic and to what extent dental symptoms existed and developed compared to pre-pandemic. For this cross-sectional study a survey has been conceptualized to determine OHRQoL, stress, depression and anxiety and their specific confounders in a German cohort. Validated questionnaires as OHIP-G14, PHQ-Stress and PHQ-4 have been implemented. Altogether 1178 participants completed the survey between May and August 2020. The overall OHIP-G14 sum score of 4.8 ± 7.5 indicated good OHRQoL. 21% of the participants (n = 248) reported toothache, 23% (n = 270) mucosal problems, 31% (n = 356) hypersensitivity of the teeth and 27% (n = 305) myofacial pain. The PHQ-Stress score (4.5 ± 3.5) demonstrated a mild severity of stress. Depression and anxiety level has been mild to moderate (PHQ-4 score: 2.4 ± 2.6). 38% of the participants stated subjectively greater emotional burden compared to pre-pandemic. Statistically significant differences exist for OHRQoL, stress, anxiety and depression levels between participants with greater, equal or less emotional burden compared to pre-pandemic. COVID-19 history and aggravated levels of depression, anxiety, and stress seem to associate with lower OHRQoL. Psychosocial consequences during pandemic times and their association to oral health should be further investigated.
