Oral frailty: A concept analysis

AIM

To clarify the concept of oral frailty to provide a clear and standardized conceptual basis for further research in older people.

DESIGN

Rodgers and Knafl's evolutionary concept analysis approach.

METHODS

The narrative analysis detailedly extracted and synthesized the attributes of oral frailty, as well as its antecedents, consequences and related terms under the guidance of Rodgers' evolutionary method.

DATA SOURCES

Multiple databases including Pubmed, CINAHL and Cochrane were searched using selected search terms 'oral frail*', 'oral health' and 'aged' respectively. Articles written between 2013 and 2023 were included, and grey literature was excluded.

RESULTS

A total of 32 articles were included for further analysis and synthesis. The attributes of oral frailty were hypofunction, predisposing in nature, non-specific and multidimensional. Antecedents of prefrailty were classified into four categories, namely, sociodemographic characteristics, comorbidity, physical function and psychosocial factors. Consequences of oral frailty include three themes: increased risk of adverse outcomes, poor nutritional status and possibility of social withdrawal. Related terms that had shared attributes with oral frailty were oral health, functional dentition, oral hypofunction and deterioration of oral function.

CONCLUSIONS

Oral frailty is an age-related phenomenon reflected in decreased oral function. The findings of this concept analysis are conducive to understanding and clarifying the oral frailty, which can help clinicians or other healthcare providers to consider how to distinguish oral frailty in older adults and further promote the development of this field.

IMPACT

Oral frailty is increasingly recognized as an age-related phenomenon reflected in decreased oral function. As it is newly proposed, no consensus has been reached regarding the theoretical and operational concept of it. Through clarifying the concept, this paper will guide future healthcare research on oral frailty regarding the influencing factors, mechanisms and interventions, thus raising the awareness with regard to oral health among older adults. WHAT DOES THIS PAPER CONTRIBUTE TO THE WIDER GLOBAL CLINICAL COMMUNITY?: In the context of older adults, oral frailty is a concept that requires further research to guide future theoretical development, and the influencing factors, mechanisms and interventions need to be further studied. Raise awareness with regard to oral health among older people and more attention will be paid to the early identification and intervention of oral frailty, so as to further improve the quality of life of older adults.

Recent dental visits and family caregiving among individuals with dental symptoms: A nationwide cross-sectional study in Japan

OBJECTIVES

With the increasing number of family caregivers due to the ageing population, physical and mental health problems among caregivers are of concern. However, few studies have evaluated their oral health. This study aimed to evaluate the association between being a family caregiver and recent dental visits for dental symptoms in Japan, with consideration of gender.

METHODS

A cross-sectional study was conducted using the 2016 Comprehensive Survey of Living Conditions (CSLC) in Japan. Participants with dental symptoms were included in this study. The primary outcome was recent dental visits. The exposure variable of interest was being a primary caregiver for a family member requiring long-term care. A logistic regression analysis was conducted adjusting for contributing factors such as age, gender, marital status, working hours per week, education, household expenditure per month, self-rated health and the interaction between gender and caregiving. A stratified analysis by gender was also performed.

RESULTS

Of the 5100 eligible participants, 233 (4.6%) were family caregivers. Of all participants, 2746 (53.8%) reported dental visits. The adjusted odds ratio (aOR) of family caregivers having recent dental visits was 0.83 (95% confidence interval [CI], 0.64-1.09). In a gender stratified analysis, family caregivers were less likely to visit dental clinics than were non-family caregivers in the male subsample (aOR: 0.56, 95% CI: 0.34-0.92) but not in the female subsample (aOR: 0.99, 95% CI: 0.72-1.38).

CONCLUSIONS

The findings indicate that family caregivers, especially male caregivers, had fewer dental visits than non-family caregivers. These findings suggest the need to improve the accessibility of dental clinics to family caregivers with dental symptoms.

Healthy lifestyles and better periodontal health: Results from two large population-based surveys

AIM

To ascertain whether healthy lifestyles are associated with periodontal diseases in two large-scale surveys in the US (National Health and Nutrition Examination Survey - NHANES) and the UK Biobank.

METHODS

9854 US adults and 111 679 UK adults were included in the analyses. A healthy lifestyle score (HLS), ranging between 0 and 5, was calculated based on the reported number of healthy behaviours, including never smoking, no heavy alcohol consumption, top third of leisure-time physical activity, higher dietary quality, and ideal sleep duration. The prevalence of periodontal diseases was the primary outcome in both surveys. In the NHANES, periodontal status was assessed through a full-mouth periodontal examination, while in the UKB, only self-reported periodontal status was available.

RESULTS

Multiple regression analyses confirmed that the presence of at least 2-3 healthy behaviours (vs. 0-1) was associated with lower odds of overall and severe periodontitis (ORs 0.5, 0.4-0.6; p < .001 and 0.5, 0.3-0.8; p = .003, respectively) in the NHANES, and of bleeding gums (OR = 0.9, 0.8-1.0; p = .092) and loose teeth (OR = 0.6, 0.5-0.7; p < .001) in UKB. This association increased when considering prevalence of 4-5 healthy behaviours (vs. 0-1) in both the NHANES (periodontitis: OR = 0.3, 0.2-0.4; p < .001; severe periodontitis: OR = 0.1, 0.01-0.2; p < .001) and the UKB (bleeding gums: OR = 0.8, 0.7-0.9; p < .001; loose teeth: OR = 0.5, 0.4-0.6; p < .001). Mediation analyses revealed how these protective associations could be partially mediated (1-14%) by differences in biomarkers of systemic inflammation (white blood cells and neutrophils count as well as C-reactive protein).

CONCLUSIONS

Adoption of healthy lifestyle behaviours is associated with a lower prevalence of periodontal diseases within two large population-based samples. This relationship exhibits a dose-response pattern, implying that greater adherence to healthy habits leads to a more significant protective effect against the odds of periodontal diseases. Additionally, our findings suggest that this protective effect is, in part, mediated by reductions in systemic inflammation.

The Gothenburg Trismus Questionnaire in China: Cross-cultural adaptation and measurement invariance

OBJECTIVES

The Gothenburg Trismus Questionnaire (GTQ) is a comprehensive scale for screening and assessing trismus in head and neck (H&N) cancer and temporomandibular joint disorders (TMD) patients. This study aimed to translate and cross-culturally adapt the GTQ in China, and to test its measurement invariance.

METHODS

This study comprised 278 H&N cancer, 245 TMD, and 507 control patients. Internal consistency and test-retest reliability were tested to assess the GTQ's reliability. The validity was evaluated through composite reliability (CR), average variance extracted (AVE), and correlation tests. Multi-group confirmatory factor analysis (CFA) was used to investigate the GTQ's measurement invariance across clinical status and gender. T tests were employed to compare score differences across clinical status and gender.

RESULTS

The Chinese version of GTQ scale shows excellent internal consistency and test-retest reliability. The CR, AVE, and correlation values demonstrate the good validity of GTQ. The multi-group CFA supported configural invariance across clinical status but not metric invariance, while it supported strict invariance across gender. Additionally, t tests revealed that patients with H&N cancer and TMD scored higher than the control group, while males scored higher than females.

CONCLUSIONS

The Chinese version of GTQ serves as an effective tool for screening and assessing trismus.

Socioeconomic status in life course is associated with dental appearance dissatisfaction

The present study aimed to investigate the prevalence of dissatisfaction with dental appearance among 24-year-old Brazilian adults and the associated factors in life course. A subsample (n = 720) of the 1982 Pelotas Birth Cohort in southern Brazil was investigated at the ages of 15 and 24 years using clinical (caries and periodontal) examinations and interviews. The outcome was dissatisfaction with dental appearance at the age of 24 years. Covariate variables included socioeconomic factors, oral health, and dissatisfaction with general appearance collected during different periods of life. Poisson regression models with robust variance were applied. The prevalence of dissatisfaction with dental appearance was 43.5% (95%CI: 39.8-47.1). Individuals with downward income mobility (PR = 1.22, 95%CI: 1.07-1.79) and those always poor (PR = 1.21, 95%CI: 1.00-1.57) presented a higher prevalence of dissatisfaction with their dental appearance even after oral health variables and dissatisfaction with general appearance were controlled for. Moderate/severe malocclusion at 15 years (PR = 1.34, 95%CI: 1.13-1.59), highest experience of untreated dental caries at 24 years (PR = 1.82, 95%CI: 1.46-2.27), and dental pain experience at 24 years (PR = 1.29, 95%CI: 1.22-1.75) were associated with the outcome. Also, the prevalence of dissatisfaction with dental appearance was 20% higher (PR = 1.20, 95%CI: 1.01-1.43) among those dissatisfied with their general appearance. Our findings demonstrated a high prevalence of dissatisfaction with dental appearance among young adults. Lifetime economic disadvantage and dental problems (malocclusion at 15 years, untreated dental caries at 24 years, and dental pain at 24 years) were associated with dissatisfaction with dental appearance among young adults.

Long intergenic non-coding RNA 01126 activates IL-6/JAK2/STAT3 pathway to promote periodontitis pathogenesis

OBJECTIVES

Periodontitis seriously affects oral-related quality of life and overall health. Long intergenic non-coding RNA 01126 (LINC01126) is aberrantly expressed in periodontitis tissues. This study aimed to explore the possible pathogenesis of LINC01126 in periodontitis.

METHODS

Inflammatory model of human gingival fibroblasts (HGFs) was established. Cell Counting Kit-8 (CCK-8), wound healing assay, and flow cytometry were utilized to detect biological roles of LINC01126. Binding site of miR-655-3p to LINC01126 and IL-6 was predicted. Then, subcellular localization of LINC01126 and the binding ability of miR-655-3p to LINC01126 and IL-6 in HGFs were verified. Hematoxylin-Eosin (H&E) staining and immunohistochemistry (IHC) staining were utilized to detect tissue morphology and proteins expression of clinical samples.

RESULTS

LINC01126 silencing can alleviate cell inflammation induced by lipopolysaccharide derived from Porphyromonas gingivalis, reduce cell apoptosis, and promote cell migration. As a "sponge" for miR-655-3p, LINC01126 inhibits its binding to mRNA of IL-6, thereby promoting inflammation progression and JAK2/STAT3 pathway activation. Quantitative real-time PCR, Western Blot, and IHC results of clinical tissue samples further confirmed that miR-655-3p expression was down-regulated and IL-6/JAK2/STAT3 was abnormally activated in periodontitis tissues.

CONCLUSIONS

In summary, serving as an endogenous competitive RNA of miR-655-3p, LINC01126 promotes IL-6/JAK2/STAT3 pathway activation, thereby promoting periodontitis pathogenesis.

Simplifying Oral health evaluation: a novel approach through single-item surveys

BACKGROUND

This study adopts a novel approach of using single-item surveys to simplify the assessment of oral health status and behaviors among Japanese private sector employees. We aimed to establish the validity of self-reported oral health in relation to clinical dental examinations, and to elucidate the relationship between oral diseases, health behaviors, and self-assessments. A secondary aim was to explore the association of self-rated oral health with oral health behaviors.

MATERIALS AND METHODS

Self-administered questionnaires and dental examinations were obtained from 2262 Japanese private sector employees. Workers self-rated their overall oral health status according to five choices: "very good," "good," "fair," "poor," or "bad." Self-reports were then compared with the results of clinical dental examinations, which included measuring the oral hygiene index (DI-S), the number of decayed teeth, periodontal status (Community Periodontal Index) and number of missing teeth. Convergent validity was also tested by examining the correlations of self-reported oral health status with oral health behaviors.

RESULTS

Overall, 30.8% of workers reported their oral health as "poor" or "bad." "Poor" or "bad" oral health status was significantly correlated with missing teeth, periodontitis, and decayed teeth. However, lower correlations were found for gingivitis and the oral hygiene index. Most self-reported oral health behaviors were correlated with self-rated oral health; exceptions were "tooth brushing instructions received in a dental clinic," "having a primary-care dentist," and "habitual snacking between meals."

CONCLUSIONS

Self-rated oral health provides reasonably valid data, and correlated well with clinically assessed oral health status, including dental caries, periodontal status, and tooth loss. Convergent validity was also found for oral health behaviors.

The oral organ: A new vision of the mouth as a whole for a gerophysiological approach to healthy aging

This article brings a new perspective on oral physiology by presenting the oral organ as an integrated entity within the entire organism and its surrounding environment. Rather than considering the mouth solely as a collection of discrete functions, this novel approach emphasizes its role as a dynamic interphase, supporting interactions between the body and external factors. As a resilient ecosystem, the equilibrium of mouth ecological niches is the result of a large number of interconnected factors including the heterogeneity of different oral structures, diversity of resources, external and internal pressures and biological actors. The manuscript seeks to deepen the understanding of age-related changes within the oral cavity and throughout the organism, aligning with the evolving field of gerophysiology. The strategic position and fundamental function of the mouth make it an invaluable target for early prevention, diagnosis, treatment, and even reversal of aging effects throughout the entire organism. Recognizing the oral cavity capacity for sensory perception, element capture and information processing underscores its vital role in continuous health monitoring. Overall, this integrated understanding of the oral physiology aims at advancing comprehensive approaches to the oral healthcare and promoting broader awareness of its implications on the overall well-being.

Influence of freeze-dried bone allograft on free gingival graft survival and alveolar ridge maintenance in socket seal procedures: a randomized controlled clinical trial

PURPOSE

This study aimed to investigate the viability of free gingival grafts (FGG) and assess clinical and radiographic changes in the alveolar ridge following socket seal surgery with or without freeze-dried bone allograft (FDBA).

MATERIALS AND METHODS

Twenty-eight anterior and premolar tooth extractions were randomly allocated to 2 groups: socket graft of FDBA sealed with FGG (n = 15) and control with empty sockets sealed solely with FGG (n = 13). Photographs taken at 3, 7, 14, and 30 days post-surgery assessed FGG viability. Alveolar ridge volume was clinically evaluated via intraoral scanners before surgery and at 1 and 3 months post-surgery. CBCT scans taken immediately post-surgery and 3 months later assessed alveolar ridge dimensions.

RESULTS

FGG viability in both groups increased from day 3 and reached the maximum score on day 14. Alveolar ridge volume reduction at 3 months in the FDBA group was comparable to the control group. Buccal alveolar bone height reduction was significantly higher in the FDBA group than the control group, while palatal alveolar bone height was comparable. Alveolar bone width reduction was evident but not statistically significant between the groups. The FDBA group exhibited a significant alteration in bone volume compared to the control group.

CONCLUSION

Viability of FGG was not affected by graft filling materials. Sealing the socket with FGG effectively preserved socket integrity and ridge volume in minor socket defects using either graft filling material or not. This study was registered on 4 January 2021 on Thai Clinical Trials Registry (TCTR20210104001).

The economic and societal impact of periodontal and peri-implant diseases

Periodontal and peri-implant diseases result from a chronic inflammatory response to dysbiotic microbial communities and are characterized by inflammation in the soft tissue and the ensuing progressive destruction of supporting bone, resulting in tooth or implant loss. These diseases' high prevalence, multifactorial etiology, extensive treatment costs, and significant detriment to patients' quality-of-life underscore their status as a critical public health burden. This review delineates the economic and sociocultural ramifications of periodontal and peri-implant diseases on patient welfare and healthcare economics. We delve into the implications of diagnosis, treatment, supportive care, and managing destructive tissue consequences, contrasting these aspects with healthy patients.

Oral health-related quality of life and periodontal status according to smoking status

INTRODUCTION

Studies evaluating smoking and periodontal status show controversial results regarding the impact on oral health-related quality of life (OHRQol). The aim was to evaluate the association between OHRQol and periodontal status in patients according to their smoking habit.

METHODS

Cross-sectional study with a total of 100 patients (31.44 ± 8.50 years, 55% females) answered the short version of Oral Health Impact Profile (OHIP-14) and underwent a periodontal examination. Associations between periodontal status and total mean OHIP-14 scores related with smoking habit were analysed with Kruskal-Wallis test.

RESULTS

Mean percentage of sites with Bleeding on Probing (BOP), Clinical Attachment Loss (CAL) and Number of Teeth were significantly different between current smokers (n = 53) and never (n = 40) or former smokers (n = 7; p < 0.05). There was no significant difference for Periodontal Probing Depth (PPD) in relation to smoking status. A total mean OHIP-14 score of 13.07 was observed for the entire sample. The corresponding total mean OHIP-14 scores, for current smokers, never smokers and former smokers, were 15, 10 and 13 (p = 0.280), respectively. The domains social disability and handicap of the OHIP-14 were worse in current smokers (p = 0.028 and p = 0.026, respectively).

CONCLUSION

Current smoking was associated with a negative influence on OHRQoL in the domain of social disability and handicap. In addition, smokers have worse periodontal status, related to less BOP, greater CAL and fewer teeth than never and former smokers.

An IoT-based aptasensor biochip for the diagnosis of periodontal disease

Severe periodontitis affects nearly 1 billion individuals worldwide, highlighting the need for early diagnosis. Here, an integrated system consisting of a microfluidic chip and a portable point-of-care (POC) diagnostic device is developed using a polymethyl methacrylate (PMMA) chip fabrication and a three-dimensional printing technique, which is automatically controlled by a custom-designed smartphone application to routinely assess the presence of a specific periodontitis biomarker, odontogenic ameloblast-associated protein (ODAM). A sandwich-type fluorescence aptasensor is developed on a microfluidic chip, utilizing aptamer pair (MB@OD64 and OD35@FAM) selectively binding to target ODAM. Then this microfluidic chip is integrated into an automated Internet of Things (IoT)-based POC device, where fluorescence intensity, as a signal, from the secondary aptamer binding to ODAM in a sandwich-type binding reaction on the microfluidic chip is measured by a complementary metal oxide semiconductor (CMOS) camera with a 488 nm light-emitting diode (LED) excitation source. Obtained signals are processed by a microprocessor and visualized on a wirelessly connected smartphone application. This integrated biosensor system allows the rapid and accurate detection of ODAM within 30 min with a remarkable limit of detection (LOD) of 0.011 nM under buffer conditions. Clinical application is demonstrated by successfully distinguishing between low-risk and high-risk individuals with 100 % specificity. A strong potential in the translation of this fluorescence-based microfluidic aptasensor integrated with an IoT-based POC system is expected to be employed for non-invasive, on-site, rapid, and accurate ODAM detection, facilitating periodontitis diagnosis.

Periodontal conditions and association of periodontitis with oral-health-related quality of life in patients experiencing different episodes of bipolar disorder compared with healthy controls

AIM

The aim of the present cross-sectional study was to evaluate periodontal conditions and the association of periodontitis with oral-health-related quality of life (OHRQoL) in patients with a history of bipolar disorder.

MATERIALS AND METHODS

A total of 160 participants were recruited in four groups for the study: 40 patients with euthymic episodes, 40 patients with depression, 40 patients with manic episodes and 40 systemically healthy individuals. Clinical periodontal parameters were recorded. Oral Health Impact Profile (OHIP-14) was used to measure the impact of oral health on the quality of life.

RESULTS

Bipolar disorder groups exhibited generally higher clinical parameters compared with the control group (p < .05). OHIP-14 total score (β = 3.32, 95% confidence interval [CI]: 0.08-6.56, p = .044), functional limitation (β = .89, 95% CI: 0.27-1.49, p = .005) and physical pain (β = .64, 95% CI: 0.01-1.27, p = .046) were associated with bipolar depression episodes. Psychological discomfort was associated with the presence of generalized periodontitis (β = .76, 95% CI: 0.01-1.51, p = .047) and psychological disability was associated with the presence of stage III-IV (β = .83, 95% CI: 0.07-1.59, p = .033) and generalized (β = .75, 95% CI: 0.07-1.42, p = .029) periodontitis.

CONCLUSIONS

According to this study, a history of bipolar disorder episodes (exposure) may be associated with increased prevalence and severity of periodontitis and related reported OHRQoL impacts (outcomes). Bipolar depression episodes had a higher impact on OHRQoL than other bipolar episodes.

Postextraction ridge preservation by using dense PTFE membranes: A systematic review and meta-analysis

STATEMENT OF PROBLEM

The use of dense polytetrafluoroethylene (dPTFE) membranes in alveolar ridge preservation may help reduce the risk of bacterial contamination and infection, maintaining the soft-tissue anatomy. However, systematic reviews on their efficacy in postextraction sites are lacking.

PURPOSE

The purpose of this systematic review and meta-analysis was to assess the efficacy of alveolar ridge preservation with dPTFE membranes when used alone or in combination with bone grafting materials in postextraction sites.

MATERIAL AND METHODS

An electronic search up to February 2021 was conducted by using PubMed, Embase, and the Cochrane library to detect studies using dPTFE membranes in postextraction sites. An additional manual search was performed in relevant journals. Clinical and radiographic dimensional changes of the alveolar ridge, histomorphometric, microcomputed tomography, implant-related findings, and rate of complications were recorded. One-dimensional meta-analysis was performed to calculate the overall means and 95% confidence intervals (α=.05).

RESULTS

A total of 23 studies, 14 randomized controlled trials, 4 retrospective cohort studies, 3 case series, and 2 prospective nonrandomized clinical trials, met the inclusion criteria. Five studies were included in the quantitative analysis. The meta-analysis revealed that the use of dPTFE membranes resulted in a statistically significant (P=.042) increase in clinical keratinized tissue of 3.49 mm (95% confidence interval [CI]: 0.16, 6.83) when compared with extraction alone. Metaregression showed that the difference of 1.10 mm (95% CI: -0.14, 2.35) in the radiographic horizontal measurements was not significant (P=.082), but the difference of 1.06 mm (95% CI: 0.51, 1.62) in the radiographic vertical dimensional change between dPTFE membranes+allograft and extraction alone was statistically significant (P<.001).

CONCLUSIONS

The use of dPTFE membranes was better than extraction alone in terms of keratinized tissue width and radiographic vertical bone loss.

British Society of Paediatric Dentistry: A policy document on dental neglect in children

The British Society of Paediatric Dentistry's (BSPD) first policy document on dental neglect was published online in 2009. It proposed a new original definition of dental neglect, discussed the identification of dental neglect and recommended adopting a tiered response, with three stages of intervention according to level of concern. Furthermore, it detailed how the dental team should both contribute to the child protection process and implement wider measures to safeguard and promote children's welfare. Since 2009, these concepts have been widely adopted in the UK and beyond. Furthermore, there have been significant advances in both research and practice. Policy documents produced by the BSPD represent a majority view, based on the consideration of currently available evidence, and are tailored to a UK working environment. Although this updated document's recommendations remain broadly unchanged, this version reflects the professions' progress in understanding dental neglect and minor updates to terminology and, following a consultation process, has been amended to address the needs of two main audiences-dental professionals and nondental health and social care professionals-in order to enhance interdisciplinary working.

Prevalence of dental visits in older Japanese adults receiving public assistance

OBJECTIVES

Exemption from paying dental care costs among recipients of public assistance contributes to universal health care coverage. Although this system might reduce the financial barriers to dental care among patients, there are still several other barriers for public assistance recipients. Therefore, this study examined whether receiving public assistance was associated with a higher prevalence of dental visits for any reason, treatment and prevention.

METHODS

Data were obtained from 16 366 respondents from the 2019 wave of a nationwide cohort study on older adults in Japan. Poisson regression analyses with robust error variance were used to examine the associations between receiving public assistance and dental visits, adjusting for number of teeth, dental pain, periodontal conditions, age, sex, number of family members, education, equivalent household income, working status, instrumental activities of daily living, medical conditions, depressive symptoms, instrumental support and geographical variations.

RESULTS

More than half of the non-recipients of public assistance visited a dentist for some reason in the past 6 months. Meanwhile, only 37% of the recipients visited a dentist. In addition, almost half of the non-recipients had treatment visits, while only 34% of the recipients visited. Furthermore, 46% of the non-recipients had dental visits for prevention, while 32% of the recipients had preventive visits. In the fully adjusted models, compared to non-recipients, public assistance recipients were 24% (Prevalence Ratio [PR]: 0.76, 95% Confidence Intervals [CI]: 0.64, 0.90), 23% (PR: 0.77, 95% CI: 0.65, 0.92) and 21% (PR: 0.79, 95% CI: 0.65, 0.95) less likely to have dental visits for any reason, treatment, and prevention, respectively.

CONCLUSIONS

Although recipients were exempted from dental treatment fees, receiving public assistance was associated with a lower prevalence of dental visits for any reason, treatment and prevention. Future studies should identify the barriers to accessing dental care among public assistance recipients to improve dental visits.

The association between malocclusion and health-related quality of life in adolescents: A mediation analysis

This study investigated the role of oral health-related functional limitations and social well-being, self-perceived health, psychosocial factors, and social support in mediating the impact of malocclusion on health-related quality of life (HRQoL). A school-based 6-month cohort study was conducted with 376 12-year-old deprived adolescents. Measures at baseline included malocclusion (DAI score), dental caries, sociodemographic characteristics, psychosocial traits (self-esteem, sense of coherence, oral health beliefs), and social support. The oral health-related functional limitations and symptoms (social well-being) domains of the CPQ11-14 , self-perceived health, and HRQoL (Kiddo-KINDL) were evaluated at the 6-month follow-up. Associations between observed and latent variables (social support, psychosocial factors, and HRQoL) were evaluated using structural equation modelling, according to the Wilson and Cleary theoretical model. Malocclusion was indirectly associated with worse HRQoL, mediated by functional limitations, social well-being, and self-perceived health. Better psychosocial status was directly associated with better HRQoL, and higher social support was indirectly associated with better HRQoL via psychosocial factors. Dental caries experience, female sex, and lower family income were indirectly associated with worse HRQoL. The impact of malocclusion on HRQoL was mediated by oral health-related functional limitations, social well-being, and self-perceived health. Sociodemographic and psychosocial factors, and social support also impacted HRQoL.

Structural Relationships between Asthma and Dental Caries in Children: A Birth Cohort Study in Southern Brazil

INTRODUCTION

There is an inconclusive causal association between asthma symptoms and dental caries in the primary dentition. This study aimed to investigate, using SEM (structural equation modeling), a possible causal relation between asthma and dental caries in the primary dentition.

METHODS

Using data from the 2004 Pelotas Birth Cohort Study, a sub-sample of 1,303 individuals was selected. Dental caries was clinically evaluated at 5 years old based on decayed, missing, and filled tooth (dmft) index criteria. Asthma-related symptoms (wheezing and shortness of breath) at 1- and 4-year-olds composed a latent variable and were the main exposures to caries occurrence. SEM was used to identify possible direct, indirect, and mediated effects of asthma in primary dentition dental caries.

RESULTS

The general prevalence of caries at age 5 was 1.95 (SD: 3.56). When comparing the dmft values for children with asthma symptoms and those without, they presented similar values in both periods where asthma symptoms were evaluated (1- and 4-year-old). SEM analysis showed that asthma was neither directly nor indirectly related to dental caries.

CONCLUSION

Asthma, using a latent variable constructed based on asthma symptoms, showed no causal effect on dental caries occurrence in the primary dentition.

A German version of the Oral Impacts of Daily Performances-reliability and validity

OBJECTIVE

The Oral Impact of Daily Performances (OIDP) is a dental patient-reported outcome measure (dPROM) for the estimation of oral health-related quality of life (OHRQoL) and takes the frequency as well as the severity of problems into account; however, it is not available in German language. The aim of this study was, therefore, to evaluate the reliability and validity of the German version of the OIDP in patients of a private practice.

MATERIAL AND METHODS

Translation of the original OIDP version was performed by a forward-backward process. Reliability was evaluated in terms of construct stability (test-retest) for the single items and the sum scores. The responsiveness to change in oral health status was assessed by pre- and post-treatment comparison, in addition. Validity was assessed as convergent validity in comparison with other dPROMs (OHIP-14; GOHAI) and objective dental findings.

RESULTS

A total of 330 patients participated in this study (mean age: 42.0 (18.0)). The OHRQoL of the participants was relatively high (OIDP score 4.3 (SD 14.3), OHIP score 4.8 (SD 5.3), GOHAI score 54.2 (SD 5.4)). A moderate construct stability for the total OIDP-score (ICC 0.686) was found whilst reliability for the single items varied between 0.179 (social contact) to 0.559 (showing teeth). Significant correlations were found for OIDP and OHIP (p < 0.001; r = 0.361) and OIDP and GOHAI (p < 0.001; r =  - 0.391) indicating moderate validity with a tendency to even stronger correlations for OIDP-s and OIDP-f (r ≥ 0.500).

CONCLUSIONS

The German version of the OIDP demonstrated sufficient reliability and validity. OIDP's general performance should be interpreted cautiously as the outcome was detected in a specifically healthy population.

CLINICAL RELEVANCE

The OIDP is yet the only dPROM that evaluates both severity as well as frequency which makes validation interesting regarding specific target populations.

Effect of alveolar ridge preservation on peri-implant mucositis and peri-implantitis prevalence: A multicenter, cross-sectional study

OBJECTIVES

Alveolar ridge preservation (ARP) is a procedure with the aim to reduce bone resorption that occurs after tooth extraction, facilitating the following implant placement. The aim of this cross-sectional study was to evaluate the prevalence of mucositis and peri-implantitis around implants inserted in sites treated with ARP and to investigate possible risk factors.

MATERIALS AND METHODS

Patients who received at least one dental implant inserted in a grafted socket were considered eligible for this study. Patients were recalled for a follow-up visit; medical history, clinical and demographic data were collected. Univariate logistic regression analyses have been performed for both implant-level and patient-level variables. Indeed, moderation analysis was used to investigate the indirect relationship between age and marginal bone level.

RESULTS

Fifty-one patients who received 61 implants were enrolled in this cross-sectional study. Thirty-three implants were classified as "healthy" (54.1%), 23 implants showed signs of peri-implant mucositis (37.7%), and 5 implants were diagnosed with peri-implantitis (8.2%). Data analyzed at the patient level showed that 49% of the patients were healthy, 45.1% of the patients had mucositis and 5.9% of the patients were affected by peri-implantitis. Mandibular sites and type III grafted sockets showed a significant association with peri-implantitis; in addition, a history of periodontitis and an increase in age showed higher risks of developing mucositis or peri-implantitis.

CONCLUSIONS

Implants inserted in grafted sockets showed favorable rates of healthy implants in the long term.

CLINICAL RELEVANCE

The ridge preservation procedures do not seem to increase the risk of developing mucositis or peri-implantitis.

Oral Health-Related Quality of Life in Adult Patients with Depression or Attention Deficit Hyperactivity Disorder (ADHD)

The aim of this cross-sectional study was the evaluation of the oral health-related quality of life (OHRQoL) in patients with depression or attention-deficit/hyperactivity disorder (ADHD) in comparison with a group of mentally healthy individuals. Patients from the Department of Psychiatry and Psychotherapy, University of Leipzig, Germany, were recruited. A healthy comparison group (HC) was recruited from the Department of Cariology, Endodontology and Periodontology. The OHRQoL was assessed using the Oral Health Impact Profile G14 (OHIP G14). Furthermore, a questionnaire regarding oral hygiene behaviour was applied. A total of 141 patients with depression or ADHD (depression n = 94, ADHD n = 47) and 145 HC individuals with a balanced age and gender distribution were surveyed. OHIP G14 median scores were significantly higher in the overall psychiatric patient group compared to HC (5.00 vs. 0.00, p < 0.001). This was also found for the four dimensions of OHIP G14 (p < 0.001). The OHIP G14 sum score of patients with depression and ADHD was comparable (5.00 vs. 6.50, p = 0.302). A significant association among psychiatric patients between smoking, gum bleeding, professional tooth cleaning, oral health education, interdental cleaning, and elevated OHIP scores was found (p < 0.001). In conclusion, patients with depression and adults with ADHD show a reduced OHRQoL. A contradictory association between oral hygiene/oral health behaviour and OHRQoL supports the hypothesis of a changed perception of oral conditions in patients with mental diseases. Interdisciplinary collaboration between psychiatric specialists and dentists should be fostered.

Quality and readability of web-based information on dental caries in Arabic: an infodemiological study

BACKGROUND

Web-based information on dental caries in Arabic remains poorly understood. This study aimed to assess the quality and readability of web-based information about dental caries in Arabic.

METHODS

The first 100 websites in Arabic about dental caries were retrieved from Google and Bing using common terms. The websites were classified and evaluated for quality based on the Journal of the American Medical Association (JAMA) benchmark criteria, the DISCERN tool, and the presence of the Health on the Net Foundation Code of Conduct (HONcode). Readability was assessed using online readability indexes.

RESULTS

A total of 102 Arabic websites were included. The JAMA benchmark score was low (m = 0.36, SD = 0.56), with 67.7% failing to meet any of the JAMA criteria. The DISCERN total score mean was 37.68 (SD = 7.99), with a majority (67.65%) of moderate quality. None of the websites had the HONcode. Readability was generally good, with 52.94% of websites having a Flesch-Kincaid Grade Level (FKGL) < 7, 91.18% having a Simple Measure of Gobbledygook (SMOG) < 7, and 85.29% having a Flesch reading ease (FRE) score ≥ 80. There was a positive correlation between JAMA and DISCERN scores (p < 0.001). DISCERN scores were positively correlated with the number of words (p < 0.001) and sentences (p = 0.004) on the websites. However, JAMA or DISCERN scores were not correlated with FKGL, SMOG, or FRE scores (p > 0.05).

CONCLUSIONS

The quality of Arabic dental caries websites was found to be low, despite their readability. Efforts are needed to introduce more reliable sources for discussing dental caries and treatment options on sites aimed at Arabic populations.

Role of behavioural and age-related factors in the long-term impact of tooth loss on oral health-related quality of life: A 25-year follow-up of Swedish older adults

OBJECTIVES

The primary aim of this study was to assess any long-term association between tooth loss at age 50 and subsequent impaired oral health-related quality of life, OHRQoL, at age 65, 70 and 75, adjusted for time invariant socio-demographic-and time variant behavioural and age-related factors in terms of disadvantages with functional, social, health and psychological concerns. As a second aim, this study examined whether behavioural- and age-related factors played a role in explaining any long-term association between early tooth loss and subsequent OHRQoL.

METHODS

In 1992, 6346 residents, aged 50, consented to participate in a prospective cohort study and 3060 completed postal questionnaire follow-ups every fifth year (six in total) until 2017. Information on tooth loss was assessed at baseline at age 50. Behavioural- and age-related covariates were assessed repeatedly at ages 65, 70 and 75. OHRQoL was the repeated outcome measure assessed by the Oral Impact on Daily Performance, OIDP at age 65, 70 and 75. Generalized Estimating Equations, GEE, with binomial logit function was used to test the association between tooth loss and prevalence of oral impacts (OIDP) adjusting for counfounders and potential mediators. The role of behavioural and age-related factors in explaining the association between early tooth loss and OHRQoL was tested using the change in estimate approach.

RESULTS

Tooth loss and time variant behavioural- and age-related covariates associated independently with higher odds of impaired OHRQoL across time. The long-term impact of tooth loss seemed to be partly explained by time variant covariates related to functional and psychological concerns. Participants who had excessive tooth loss at age 50 were 2.5 times more likely to experience oral impacts before adjustment of covariates. After adjustment of functional- and psychological-covariates, participants were, respectively, 1.6 times and 1.4 times more likely to experience oral impacts.

CONCLUSION

This study revealed that early tooth loss at age 50 was independently associated with subsequent impaired OHRQoL at ages 65, 70 and 75. The aspects of behavioural- and age-related factors in terms of disadvantages in functional and psychological concerns seemed to play a role in explaining the long-term impact of tooth loss on impaired OHRQoL. A mid-life approach to the prevention of tooth loss for the protection of subsequent adverse health outcomes should guide health promotion interventions and also be recognized by oral health care providers both for patient interaction and clinical decision making.

Treatment alternatives for the rehabilitation of the posterior edentulous maxilla

Rehabilitation of the edentulous maxilla with implant-supported fixed dental prostheses can represent a significant clinical challenge due to limited bone availability and surgical access, among other factors. This review addresses several treatment options to replace missing teeth in posterior maxillary segments, namely the placement of standard implants in conjunction with maxillary sinus floor augmentation, short implants, tilted implants, and distal cantilever extensions. Pertinent technical information and a concise summary of relevant evidence on the reported outcomes of these different therapeutic approaches are presented, along with a set of clinical guidelines to facilitate decision-making processes and optimize the outcomes of therapy.

Latest Concepts in Endodontic Management of Pregnant Patients

Pregnant patients and how to manage their treatments is one of the most important challenges in endodontic practice. Endodontic treatment on pregnant women is sometimes an emergency condition to control toothache due to irreversible pulpitis and odontogenic infection. Tooth decay, oral health, local and general anesthesia, analgesics, antibiotic prescription, drug interactions, and X-ray radiation are the most important considerations that may impact treatment planning and endodontic practice in pregnancy. The aim of this article is to notify and explain the latest concepts in the endodontic management of pregnant patients.

The dentist-patient relationship and oral health-related quality of life among older adults: A cohort study

OBJECTIVES

To assess the association between aspects of the dentist-patient relationship at age 65 and Oral Impacts on Daily Performances (OIDP) at ages 65 and 70 and to examine whether dental avoidance behaviours play a role in explaining that association.

BACKGROUND

Information about the quality of the dentist-patient relationship is important for dental care provision and healthy ageing.

METHOD

Secondary data analysis of a cohort study of Norwegians born in 1942. The participation rate in 2007 (age 65) and 2012 (age 70) was, respectively, 58.0% (n = 4211) and 54.5% (n = 3733). A total of 70.0% (n = 2947) of the baseline participants responded in 2012. Dentist-patient relationship aspects were assessed in terms of communication with the dentist, satisfaction with dental care, unpleasant experiences and changes of dentist. Generalised Estimating Equations (GEEs) were used to account for repeated measurements.

RESULTS

Prevalence of oral impacts (OIDP) was 29.0% in 2007 and 28.4% in 2012. Participants who received communication on oral hygiene during dental visits had a higher likelihood, whereas participants who reported satisfaction with dental care, no unpleasant experience and did not change dentist had a lower likelihood of reporting oral impacts over these 5 years. Corresponding odds ratios were: 1.2 (95% CI 1.0-1.5), 0.4 (95% CI 0.3-0.5), 0.6 (95% CI 0.5-0.7) and 0.5 (95% CI 0.3-0.6). Associations between dentist-patient relationship aspects and OIDP remained unchanged after adjustment for avoidance behaviours.

CONCLUSION

Training dentists in relationship skills might improve social interaction with patients and the oral health-related quality of life of older people in Norway.

Dental care utilization among home care recipients, nursing home residents, and older adults not in need of long-term care: An observational study based on German insurance claims data

OBJECTIVES

To describe and compare dental care utilization (DCU) among home care recipients, nursing home residents, and older adults not in need of long-term care (LTC).

METHODS

Using nationwide claims data of 8 German statutory health and LTC insurance funds, proportions of home care recipients (n = 68,137), nursing home residents (n = 21,167), and non-LTC dependents (n = 632,205) aged 65+ years with DCU in 2017 were determined and compared. Associations between DCU and individual characteristics and setting were investigated via multivariable logistic regression. The proportions of individuals with DCU one year before and after transition to (a) home care (n = 23,590) and (b) nursing home care (n = 6,583) were compared.

RESULTS

Proportions of home care recipients and nursing home residents with DCU were lower compared to non-LTC dependents (51.9, 53.1, and 73.2%, respectively). Adjusted odds ratios for DCU for home care recipients vs. non-LTC dependents ranged from 0.55 (LTC grades 1/2; 95% confidence interval 0.54-0.56) to 0.38 (LTC grades 4/5; 0.36-0.40). For nursing home residents vs. non-LTC dependents they ranged from 0.69 (3; 0.65-0.72) to 0.67 (4/5; 0.63-0.71). Women, older individuals, those with 0-1 diseases of the Elixhauser comorbidity index, dementia, and those from West Germany were also less likely to utilize dental care than their counterparts. Utilization decreased after transition to home care (60.0 vs. 55.6%) and increased after transition to nursing homes (46.1 vs. 53.5%).

CONCLUSIONS

Nursing home residents and especially home care recipients utilized dental care less frequently than older non-LTC dependents. Organizational barriers for dental care utilization and ways to remove them should be investigated.

CLINICAL SIGNIFICANCE

Dental care utilization among LTC dependents is low and should be improved in both the home care and nursing home setting.

Oral Health and Community Nursing: a Practical Guide to the Delivering Better Oral Health Toolkit for Adults

Despite being largely preventable, oral diseases are the major contributor to chronic conditions nationally and globally. If left untreated, oral diseases have many harmful effects throughout life on our patients including pain and infection, and can lead to difficulties with eating, sleeping, socialising and wellbeing. Oral health inequalities exist across our population, and particularly affect vulnerable, disadvantaged and socially excluded groups in society. Oral health is a key indicator for overall health, and is inextricably interlinked with general health. Hence, existing health messages that community nursing teams provide contribute towards oral health. Community nurses are in an established position to provide and reinforce positive oral health messages to their patients, as well as signpost to available dental services. This paper aims to support community nurses with a practical resource for key evidence-based oral health preventative advice, and input into how their patients can access dental care.

Causes and Management of Halitosis: A Narrative Review

Halitosis is defined as the presence of an unpleasant odor in exhaled air, regardless of its cause. In most patients with halitosis, the condition causes embarrassment and interferes with social interactions and daily life. Furthermore, bad breath can be a sign of an underlying disease. Understanding the factors and causes that lead to halitosis and its manifestations could facilitate proper management of this condition. To properly diagnose and treat patients, healthcare professionals, including primary care physicians and dental professionals, must be familiar with the etiology and appropriate management of the disease. Consequently, this review aims to provide practitioners with up-to-date information on the etiological factors of halitosis to facilitate the establishment of preventive measures and provide accurate diagnosis and management.

Association of oral health with various work problems: a cross-sectional study of Japanese workers

BACKGROUND

Oral diseases affect quality of life and known to decrease productivity. We examined the impact of oral health status on various types of work problems.

METHODS

This cross-sectional study used data from an internet-based self-report questionnaire survey administered to workers in Japan. Responses to the questionnaire regarding seven types of oral health-related work problems (1. Stress; 2. Lack of focus; 3. Lack of sleep; 4. Lack of energy; 5. Lack of communication due to halitosis; 6. Lack of communication due to appearance; 7. Lack of ability due to dental-related pain) were investigated and statistically analyzed. Explanatory variables were self-reported oral health status, number of teeth, and gum bleeding. To examine the association of oral health with the presence of work problems, logistic regression analysis was used to estimate the odds ratio (OR) and 95% confidence interval (CI). Age, sex, educational attainment, income, the presence of diabetes, and industrial classifications were used as the covariates.

RESULTS

A total of 3,930 workers (mean age: 43.3 (SD = 11.7), 2,057 males and 1,873 females) were included. Overall, a total of 6.2% of workers reported having at least one oral health-related work problem in the past year, whereas 21.8% of those with poor self-reported oral health reported work problems. Workers with poor self-reported oral health were 3.58 (95% CI (1.70-7.56) times higher odds of reporting work problems than those with excellent self-reported oral health.

CONCLUSIONS

Oral health was found to be associated with various work problems. Oral health promotion policies are needed in the workplace.

The Potential of a Saliva Test for Screening of Alveolar Bone Resorption

Oral health screening is important for maintaining and improving quality of life. The present study aimed to determine whether patients with a certain level of alveolar bone resorption could be screened by salivary bacterial test along with their background information. Saliva samples were collected from 977 Japanese patients, and the counts of each red-complex, that is, Porphyromonas gingivalis, Treponema denticola, and Tannerella forsythia, were measured using quantitative polymerase chain reaction analysis. Mean bone crest levels (BCLs) were measured using a full-mouth periapical radiograph. Multiple logistic regression analysis was used to determine associations between BCLs (1.5-4.0 mm in 0.5 mm increments) and explanatory variables, such as the number of each red-complex bacteria and the patients' age, sex, number of teeth, stimulated saliva volume, and smoking habits. When the cutoff BCL value was set at 3.0 mm, the area under the curve, sensitivity, and specificity values were optimal at 0.86, 0.82, and 0.76, respectively. In addition, all tested explanatory variables, except sex and T. denticola count, were significantly associated with BCLs according to a likelihood ratio test (p < 0.05). Additionally, the odds ratio (OR) was substantially increased when a patient was >40 years old and the bacterial count of P. gingivalis was >10⁷ cells/µL (OR: >6). Thus, P. gingivalis count and patients' background information were significantly associated with the presence of a certain amount of bone resorption, suggesting that it may be possible to screen bone resorption without the need for radiography or oral examination.

The Epidemiology of Dental Pathologies in Elderly Patients Admitted to a Tertiary Level Hospital in Oradea, NW Romania: A 5-Year Retrospective Study

Oral diseases can affect the quality of life of all individuals, including elderly people. In elderly people, the associated general diseases can increase the risk of dental pathologies or can impact their treatment. The main aim of this study was to identify elderly patients with dental pathology out of the total number of patients admitted to the Department of Oral and Maxillofacial Surgery at a tertiary-level hospital in North-Western Romania. Another aim was to describe the characteristics of the patients included in this study, as well as to analyze data from patients with dental pathologies. In this retrospective study, the medical records of patients admitted to the Department of Oral and Maxillofacial Surgery at the Bihor County Emergency Hospital between 2016 and 2020 were analyzed, with a focus on patients aged 65 years or more. After applying the exclusion criteria, 721 patients were kept in the study, of which 316 (43.8%) had at least one dental pathology. Most elderly patients with dental pathologies were admitted in 2018 (n = 89). The most common associated systemic diseases were arterial hypertension (n = 268) and ischemic heart disease (n = 233), while the most common dental pathologies were pulpitis (n = 185), chronic apical periodontitis (n = 61) and abscesses (n = 35). Most patients were either healed or had an improved condition at the time of discharge. The great number of dental pathologies, as well as the diversity in dental pathologies, underline the necessity for better preventive programs aimed not only at children, adolescents or young people but at the elderly population as well.

Knowledge, perceptions, and behavior regarding children's oral health among Syrian pediatricians: a cross-sectional study

BACKGROUND

Oral health has a direct impact on health-related quality of life (HRQoL). Hence, general health and oral health cannot be separated. Pediatricians play a pivotal role in providing primary care for infants and are the first to interact with them since birth. Therefore, the aim of this study was to evaluate the knowledge, perceptions, and behavior of Syrian pediatricians regarding children's oral health.

METHODS

This was a cross-sectional study. The questionnaire consisted of six main sections and required answers regarding demographic characteristics, knowledge, behavior, perceptions, and training received in oral health. The association between categorical variables was tested with Pearson's chi-square tests and Fishers exact tests using SPSS ver. 23.

RESULTS

The response rate was 43.12% (229/531). Most of the participants (64.02%) got a poor level of knowledge and no significant association was found between knowledge level and years of experience (p = 0.270). The majority of the participants (99.13%) perceived that diet, bacteria, and sugar exposure time are the etiological factors of dental caries. The overwhelming majority of the participants (98.25%) acknowledged the need for further oral health training during residency.

CONCLUSIONS

Most pediatricians reported a poor level of knowledge. It is recommended to update the postgraduate and residency curriculum to equip pediatricians with adequate knowledge regarding children's oral health.

Association between oral and general health related quality of life among Norwegian patients with substance use disorders in opioid agonist therapy

OBJECTIVE

Assess the association between oral and general health related quality of life using oral impacts on daily performances (OIDP) and the quality of life tool EQ-5D-5L from EuroQoL among patients with substance use disorder (SUD) who receive opioid agonist therapy.

METHOD

609 patients with SUD completed the EQ-5D-5L. A dental sub-study of 167 patients completed OIDP and an oral examination when attending outpatient clinics in Western Norway for their opioid agonist therapy. The merged analytical sample consisted of 165 patients. The association between OIDP and EQ-5D-5L was assessed by Spearman's rho and a linear multiple variable regression analysis. A line graph and a Pen's parade displayed the distributions of OIDP sum scores and EQ-5D-5L index values.

RESULTS

Overall mean summary- and index EQ-5D-5L scores were 9.97 (sd 3.25) and 0.69 (sd 0.22). Mean score for OIDP was 9.75 (sd 9.59). Spearman's rho was 0.34 (p < .01) between OIDP and EQ-5D-5L summary scores. Linear regression revealed an association adjusted for sex and age of 0.12 (95% CI 0.07-0.17) and a coefficient of determination of 0.1460.

CONCLUSION

This study reveals a strong association between OIDP and EQ-5D-5L reflecting the importance of oral health to general health for patients with SUD. Health care professionals should pay attention to oral health. Effective interventions might improve patients' oral and health related quality of life.

Technological Aspects and Evaluation Methods for Polymer Matrices as Dental Drug Carriers

The development of polymer matrices as dental drug carriers takes into account the following technological aspects of the developed formulations: the composition and the technology used to manufacture them, which affect the properties of the carriers, as well as the testing methods for assessing their behavior at application sites. The first part of this paper characterizes the methods for fabricating dental drug carriers, i.e., the solvent-casting method (SCM), lyophilization method (LM), electrospinning (ES) and 3D printing (3DP), describing the selection of technological parameters and pointing out both the advantages of using the mentioned methods and their limitations. The second part of this paper describes testing methods to study the formulation properties, including their physical and chemical, pharmaceutical, biological and in vivo evaluation. Comprehensive in vitro evaluation of carrier properties permits optimization of formulation parameters to achieve prolonged retention time in the dynamic oral environment and is essential for explaining carrier behavior during clinical evaluation, consequently enabling the selection of the optimal formulation for oral application.

Tissue engineering at the dentin-pulp interface using human treated dentin scaffolds conditioned with DMP1 or BMP2 plasmid DNA-carrying calcium phosphate nanoparticles

Hard dental tissue pathologies, such as caries, are conventionally managed through replacement by tooth-colored inert biomaterials. Tissue engineering provides novel treatment approaches to regenerate lost dental tissues based on bioactive materials and/or signaling molecules. While regeneration in the form of reparative dentin (osteo-dentin) is feasible, the recapitulation of the tubular microstructure of ortho-dentin and its special features is sidelined. This study characterized in vitro, and in vivo human EDTA-treated, freeze-dried dentin matrices (HTFD scaffolds) conditioned with calcium phosphate nanoparticles (NPs) bearing plasmids encoding dentinogenesis-inducing factors (pBMP2/NPs or pDMP1/NPs). The uptake and transfection efficiency of the synthesized NPs on dental pulp stem cells (DPSCs) increased in a concentration- and time-dependent manner, as evaluated qualitatively by confocal laser microscopy and transmission electron microscopy, and quantitatively by flow cytometry, while, in parallel, cell viability decreased. HTFD scaffolds conditioned with the optimal transfectability-to-viability concentration at 4 µg Ca/mL of each of the pBMP2/NPs or pDMP1/NPs preserved high levels of cell viability, evidenced by live/dead staining in vitro and caused no adverse reactions after implantation on C57BL6 mice in vivo. HTFD/NPs constructs induced rapid and pronounced odontogenic shift of the DPSCs, as evidenced by relevant gene expression patterns of RunX2, ALP, BGLAP, BMP-2, DMP-1, DSPP by real-time PCR, and acquirement of polarized meta-mitotic phenotype with cellular protrusions entering the dentinal tubules as visualized by scanning electron microscopy. Taken together, HTFD/NPs constitute a promising tool for customized reconstruction of the ortho-dentin/odontoblastic layer barrier and preservation of pulp vitality. STATEMENT OF SIGNIFICANCE: In clinical dentistry, the most common therapeutic approach for the reconstruction of hard dental tissue defects is the replacement by resin-based restorative materials. Even modern bioactive materials focus on reparative dentinogenesis, leading to amorphous dentin-bridge formation in proximity to the pulp. Therefore, the natural microarchitecture of tubular ortho-dentin is not recapitulated, and the sensory and defensive role of odontoblasts is sidelined. This study approaches the reconstruction at the dentin-pulp interface using a construct of human treated dentin (HTFD) scaffold and plasmid-carrying nanoparticles (NPs) encoding dentinogenic factors (DMP-1 or BMP-2) with excellent in vitro and in vivo properties. As a future perspective, the HTFD/NPs constructs could act as bio-fillings for personalized reconstruction of the dentin-pulp interface.

Clustering of Health and Oral Health-Compromising Behaviours in Army Personnel in Central Peninsular Malaysia

Health- and oral health-compromising behaviours (HOHCBs) impact the health readiness of military personnel, resulting in decreased fitness performance, thus affecting combat readiness. This study aimed to identify the clustering patterns and number of HOHCBs in army personnel in Central Peninsular Malaysia. Thus, a cross-sectional study using a multistage sampling technique and a validated 42-item online questionnaire was conducted to assess ten health (medical screening, physical activity, sedentary lifestyle, smoking status, alcohol consumption, substance abuse, aggressive behaviours, sleep, and road safety habits) and five oral health behaviour domains (tooth brushing, fluoridated toothpaste use, flossing, dental visits, and bruxism). Each HOHCB was dichotomised into healthy and health-compromising behaviour and analysed using hierarchical agglomerative cluster analysis (HACA). With the majority being males (92.5%), of other ranks (96.8%), and healthy (83.9%), 2435 army members of a mean age of 30.3 years (SD = 5.9) participated, with a response rate of 100%. HACA identified two clustering patterns: (i) 'high-risk behaviours' (30 HOHCBs) and (ii) 'most common risk behaviours' (12 HOHCBs) with a mean clustering number of 14.1 (SD = 4.1). In conclusion, army personnel in Central Peninsular Malaysia displayed 2 broad HOHCB clustering patterns, 'high-risk' and 'most common risk', with an average of 14 HOHCB clusters per person.

Outcome and associated predictors for nonsurgical management of large cyst-like periapical lesions: A CBCT-based prospective cohort study

AIM

The aim of this cone-beam computed tomography (CBCT)-based study was to evaluate the outcome of nonsurgical root canal treatment (RCT) performed for the management of large cyst-like periapical lesions (LCPL) and to identify the predictive factors affecting healing.

METHODOLOGY

Fifty-four subjects (77 permanent maxillary anterior teeth) with LCPL (>10 mm) of endodontic origin were included. A single operator performed standardized multi-visit RCT. Patients were clinically and radiographically examined at 6, 12 months, and a CBCT scan was taken at 24 months. Two independent blinded evaluators measured the pre- and postoperative volume of periapical lesions on CBCT scans using ITK snap software (version 3.8.0-beta-20181028-win64). The outcome was assessed as a percentage change in lesion volume and dichotomized as success (resolved/reduced) or failure (unchanged/enlarged). Ten preoperative (gender; age; intraoral draining sinus, soft tissue swelling, tooth discoloration, pulp canal obliteration, open apex, root resorption, cortical bone defect and lesion volume) and four intraoperative (apical extent and density of root filling; number of treatment visits and type of root filling) predictive factors were observed. Bivariate and stepwise multivariable linear regression analysis was performed to identify independent predictors affecting treatment outcomes. The significance level was set at 5%.

RESULTS

A recall rate of 88% was achieved. The success rate of RCT was 82.2% (8.9% resolved, 73.3% reduced). Median lesion volume reduction was 75% (IQR 61%-93%). No pre- or intra-operative factors were related to treatment failure. However, presence of preoperative cortical bone defect (palatal versus no cortical defect, β = -51.5; 95% CI: -86.9 to -16, p = .006) and apical extent of obturation (long versus flush, β = -27.2; 95% CI: -53.8 to -0.6, p = .04) were negatively associated with reduction in lesion volume (%).

CONCLUSION

Large cyst-like periapical lesions may be successfully managed with RCT. Preoperative cortical bone defect and apical extent of obturation may negatively influence osseous healing.

Association of overtime work duration with oral health-related quality of life in Japanese workers

PURPOSE

Overtime work is associated with a risk of developing various diseases, including oral diseases. Oral Health-Related Quality of Life (OHRQoL) is a more comprehensive assessment than those of individual diseases and can be affected by longer working hours.

METHODS

This cross-sectional study examined the association of overtime work duration with OHRQoL. Data were obtained from an online survey of Japanese workers in February 2016. OHRQoL was assessed using the Oral Health Impact Profile-49 (OHIP-49). Poisson regression with robust variance was used to estimate the ratio of means and 95% confidence intervals (CI) of overtime work duration for OHIP-49 scores after adjusting for sociodemographic and health behavior covariates.

RESULTS

Of 2,764 (2,178 male and 586 female) workers (mean age, 44.6 ± 10.0 years), those with longer duration of overtime work tended to exhibit poorer OHRQoL. The mean OHIP-49 scores of those who did not work overtime and worked for ≥5 h overtime were 27.93 ± 28.53 and 40.97 ± 38.86, respectively. After adjusting for covariates, compared to those who did not work overtime, the mean OHIP-49 score was 1.41 times higher (95% CI 1.38-1.44) for those who worked for ≥5 h overtime.

CONCLUSION

Longer overtime work duration was associated with poor OHRQoL.

ASSESSMENT OF THE QUALITY OF LIFE OF PATIENTS WITH PERIODONTAL TISSUE DISEASES (RESULTS OF A PILOT SURVEY)

OBJECTIVE

The aim: To study the quality of life of patients with periodontal disease.

PATIENTS AND METHODS

Materials and methods: The study was conducted among 189 patients, including 87 men and 102 women. Research methods - clinical method, question¬naire survey (study of the quality of life related to oral health (oral health-related quality of life - OHRQoL, ОНІР-14), medical and statistical analysis using an application package Statistica 10.0 (StatSoft, Inc., USA) and Microsoft Office Excel 2010.

RESULTS

Results: According to the results of periodontal examination, it was found that 29,1% of patients suffer from acute gingivitis, acute periodontitis - 48,1%, chronic periodontitis - 21,7%. According to the results of patients' self-assessment of the quality of life associated with oral health, a good lifestyle can be stated. Almost 50% of patients said that the most tangible problems associated with the health of their oral cavity are functional disorders (31,7%), oral pain, and difficulty eating (16,6%). Psychological problems were reported by 16,3% of respondents, among whom one-third noted a feeling of irritability and tension, dissatisfaction with eating, and also noted limitations in communication with people, and the need to interrupt food intake during its intake due to oral problems.

CONCLUSION

Conclusions: Periodontal tissue diseases reduce the quality of life of patients. Assessing the quality of life related to oral health is essential to determine the effectiveness of measures aimed at improving and preserving public health.

Perception of malocclusion and school performance in adolescents: a systematic review

This study aimed to assess the potential association between perception malocclusion and school performance in children and adolescents. An electronic search was performed in ten databases. Based on the PECO acronym (Population, Exposition, Comparator, and Outcome), the eligibility criteria included observational studies that compared the school performance of children and adolescents with and without the perception of malocclusion. There were no restrictions on the language or year of publication. Two reviewers selected the studies, extracted the data, and assessed the risk of bias by using the Joanna Briggs Institute tool for cross-sectional studies. School performance was measured by analyzing student grades; levels of absenteeism; and child or adolescent self-perception and/or the perception of parents, guardians, close friends, and teachers regarding the impact of malocclusion on school performance. The data were described narratively/descriptively. The search resulted in 3,581 registers, of which eight were included in the qualitative synthesis. These studies were published between 2007 and 2021. Two studies concluded that there was no significant association between school performance and perception of malocclusion, five studies found that only some of the children with malocclusion had their school performance affected, and one study concluded that there was a significant association between perception of malocclusion and low school performance. Considering all variables and the very low certainty of evidence, the perception of malocclusion seems to negatively impact school performance when associated with external and subjective factors. Further studies using additional measurement standards are required.

Systemic Diseases with Oral Manifestations and Their Impact on Health-Related Quality of Life

Health-related quality of life is a multidimensional concept established to evaluate the physical, psychological, and social impacts of health conditions on individuals’ well-being. Various tools for measuring health-related quality of life can be categorized into two subsets: generic and disease–specific instruments. The oral cavity can be stricken by a broad range of local and systemic diseases and their systemic treatment modalities. The most common systemic illnesses associated with oral lesions are hematologic disorders, endocrinopathies, neurological disorders, gastrointestinal conditions, mucocutaneous and rheumatic diseases, and neoplastic processes. Their manifestations in the oral cavity are, in most cases, rather nonspecific but should not be overlooked. Oral health is one of the most important parts of overall health, thus it has been proposed that poor oral health may affect health–related quality of life. The presence of oral manifestations of systemic diseases has a negative impact on the daily functioning of patients, decreasing their overall well-being. This article will review the most common systemic diseases with oral manifestations and their impact on the health–related quality of life. Oral health researchers should put a stronger emphasis on the patient-reported quality of life as a primary outcome in future clinical trials. The significance of this area has still not been widely understood in the current dental literature even though it could help improve patients’ health-related quality of life.

Unraveling the signs and symptoms of oral conditions that affect daily life activities and oral health-related quality of life

OBJECTIVES

Since oral conditions negatively affect oral health-related quality of life (OHRQoL), this study evaluated which oral clinical condition, signs, and symptoms are associated with the impact on OHRQoL, its domains, and specific daily life activities among adults.

MATERIALS AND METHODS

Data from a probabilistic sample of adults (35-44 years old) was used. The Oral Impacts on Daily Performance (OIDP) was used to evaluate OHRQoL, its domains (physical, psychological, and social), and nine daily life activities. Signs and symptoms of oral diseases (dental caries, periodontal disease, need for dental prothesis, and tooth loss) and oral self-perception were considered. Descriptive, bivariate, and multi-level analyses were conducted.

RESULTS

A total of 5,834 adults were included, of which 52.9% had some negative impact of oral conditions on OHRQoL. Difficulty in eating was the most affected daily life activity. For multiple models, dental caries lesions (cavities), filled teeth with caries, gingival bleeding, periodontal pocket, dental pain, need for upper or lower dental prosthesis, and oral health self-perception were associated (p < 0.05) with overall OHRQoL or at least one of its domains. The impact on daily life activities of each individual was associated with at least one oral condition. Dental caries lesions (cavity) and dental pain were associated (p < 0.05) with the impact on most daily life activities evaluated.

CONCLUSIONS

Different signs and symptoms of prevalent oral diseases are associated with the impact on specific daily life activities among adults, which may compromise the OHRQoL.

CLINICAL RELEVANCE

Knowledge of how signs, symptoms, and oral conditions affect OHRQoL and daily life activities can provide essential information for clinicians to establish proper disease management and preventive strategies focusing on improving patients' lives.

Medical and Dental Students' Perception of Interdisciplinary Knowledge, Teaching Content, and Interprofessional Status at a German University: A Cross-Sectional Study

Although oral health is considered a key indicator of overall health, dentistry is still neglected in medical education at the university level. Interprofessional education (IPE) is an important tool to promote collaboration among health care providers and to reduce barriers to access in health care. In this cross-sectional study, medical and dental students at Mainz University, Germany, were surveyed regarding their perception of interdisciplinary knowledge, teaching content, interprofessional standing, and attitudes toward IPE. Spearman's rank correlation was used to identify associated statements. Structural equation modeling (SEM) was performed to understand how sex, study progress, and prior education might influence student attitudes. In total, 426 medical students and 211 dental students were included in the study. Dental students rated their interdisciplinary knowledge higher than medical students. The relevance of IPE as assessed by the students correlated significantly with their motivation to continue IPE after graduation. Both groups of students valued the other discipline but rejected a combined graduate program. Students with prior professional training valued the synergy of medicine and dentistry more the students without prior training. Interprofessional knowledge and interest in IPE was higher among dental students. Understanding students' attitudes toward IPE is an important prerequisite for adapting university curricula to strengthen students' attitudes and motivation.

Does preventive dental care reduce nonpreventive dental visits and expenditures among Medicaid-enrolled adults?

OBJECTIVE

To determine whether preventive dental visits are associated with fewer subsequent nonpreventive dental visits and lower dental expenditures.

DATA SOURCES

Indiana Medicaid enrollment and claims data (2015-2018) and the Area Health Resource File.

STUDY DESIGN

A repeated measures design with individual and year fixed effects examining the relationship between preventive dental visits (PDVs) and nonpreventive dental visits (NPVs) and dental expenditures.

DATA COLLECTION/EXTRACTION METHODS

Not applicable.

PRINCIPAL FINDINGS

Of 28,152 adults (108,349 observation-years) meeting inclusion criteria, 36.0% had a dental visit, 27.8% a PDV, and 22.1% a NPV. Compared to no PDV in the prior year, at least one was associated with fewer NPVs (β = -0.13; 95% CI -0.12, -0.11), lower NPV expenditures (β = -$29.12.53; 95% CI -28.07, -21.05), and lower total dental expenditures (-$70.12; 95% -74.92, -65.31), as well as fewer PDVs (β = -0.24; 95% CI -0.26, -0.23).

CONCLUSIONS

Our findings suggest that prior year PDVs are associated with fewer subsequent NPVs and lower dental expenditures among Medicaid-enrolled adults. Thus, from a public insurance program standpoint, supporting preventive dental care use may translate into improved population oral health outcomes and lower dental costs among certain low-income adult populations, but barriers to consistent utilization of PDV prohibit definitive findings.

Oral health-related quality of life in patients with osteoarthritis of the temporomandibular joint-Results of a systematic review

OBJECTIVES

The aim of this systematic review was to assess the oral health-related quality of life (OHRQoL) of patients with osteoarthritis (OA) of the temporomandibular joint (TMJ).

METHODS

This systematic literature search applied the search terms "oral health-related quality of life AND osteoarthritis of jaw OR arthritis of temporomandibular joint AND oral health-related quality of life" in PubMed, Medline, Web of Science and Scopus. Eligibility criteria were publication until 31 August 2021, examination of children or adults with OA of TMJ, reporting of any OHRQoL measurement and a full text in English language. Two different, independent and experienced reviewers performed this systematic literature search. The analysis of respective data was qualitative. For quality appraisal, the available checklist from the Agency for Healthcare Research and Quality (AHRQ) was applied.

RESULTS

Out of 102 findings, eight studies were included in qualitative analysis. Seven clinical investigations were performed in adults aged between 34 and 43 years. The other included study was performed on children. The quality of two studies was moderate, and six studies were evaluated as of high quality. Most studies applied the 14-item short form of the oral health impact profile (OHIP 14) for assessment of OHRQoL. OHIP 14 ranged between 9.24 and 38.86 points in means of sum score. Comparison with healthy individuals revealed worse OHRQoL of OA patients in two studies. Associations between OHRQoL with either oral health, general quality of life or disease-related parameters were rarely reported and heterogeneous. Five of the included studies reported subscales of OHIP 14, showing an impairment in all subscales.

CONCLUSIONS

There are hints that patients with OA of the TMJ show a reduced OHRQoL. More studies are needed, especially regarding oral health, disease-related parameters and pain intensity and its potential influence on OHRQoL.

Quality of life and satisfaction of patients two years after endodontic and dental implant treatments performed by experienced practitioners

OBJECTIVES

To compare oral health related quality of life (OHRQoL) and patients´ satisfaction with root canal treatment (RCT) and dental implant (DI) therapy performed by experienced practitioners.

METHODS

Patients with both an RCT and a DI performed respectively by an endodontist and an oral surgeon with more than 15 years of experience two years prior to the study were included. The survival and satisfactory outcome of both treatments were verified with clinical and radiographic data. Participants completed two constructed questionnaire (one for each treatment). OHRQoL assessment included 24 items (OHIP-14 plus other relevant 10 items from the original OHIP-49 questionnaire). Satisfaction regarding duration, cost and pain (both during and after treatment) of treatment was assessed with a 0-10 scale and perceptions with true/false questions. Weighted sums for each dimension, total OHIP scores, prevalence of impact and general satisfaction of patients were then calculated for DI and RCT and compared using the Wilcoxon test for related samples. Patients´ perceptions were compared with Chi-square test.

RESULTS

Total OHIP scores were low for both treatments (8.82 and 7.87, respectively for RCT and DI). No significant differences were detected in OHIP total score or any dimension, except for physical pain (significantly higher for RCT than DI (p=0.044)). All patients were satisfied with both treatments; however, patients recalled that pain during treatment was significantly worse for RCT than DI (p=0.003).

CONCLUSIONS

High long-term OHRQoL and satisfaction is expected with either DI or RCT performed by experienced practitioners; however, physical pain dimension is higher for RCT.

CLINICAL SIGNIFICANCE

This study demonstrated a high satisfaction and long-term quality of life of patients undergoing both DI and RCT if treatments provide a functional balance and are performed by experienced practitioners. Very importantly, all participants had received both treatment modalities and being their own control eliminates individual variability.
