Association between obesity/overweight and dental caries in psychiatric patients

[Research Progress of Cellular Lipid Droplets in Oral Diseases]

Lipid droplets are dynamic multifunctional organelles composed of a neutral lipid core and a phospholipid monolayer membrane modified by a specific set of proteins. PAT family proteins are the most characteristic lipid droplet proteins, playing an important role in regulating lipid droplet structure, function, and metabolism. The biogenesis of lipid droplets involves neutral lipid synthesis and the nucleation, budding, and growth of the lipid droplets. Lipid droplets not only serve as the energy metabolism reserve of cells but also participate in intracellular signal transduction and the development of inflammation and tumor. Lipid droplets are closely connected to and interact with various organelles, regulating the division, the transportation, and the genetics of organelles. The complexity of lipid droplets biogenesis and the diversity of their functions may have provided a physiological basis for the pathogenesis and development of diseases, but further research is needed in order to better understand the relevant processes. Published findings have helped elucidate the association between lipid droplets and diseases, such as obesity, non-alcoholic fatty liver disease, neurodegenerative disease, cancer, and cardiovascular disease, but the relationship between lipid droplets and oral diseases has not been fully studied. Topics that warrant further research include the role and mechanisms of lipid droplets in the pathogenesis and development of oral diseases, the relationship between oral diseases and systemic diseases, and translation of the effect of lipid droplets on oral diseases into valuable clinical diagnostic and treatment methods. Herein, we reviewed the biogenesis and functions of lipid droplets and the progress in research concerning lipid droplets in oral diseases, including mouth neoplasms, periodontitis, and dental caries.

Relationship between body mass index and oral health indicators: a cross-sectional study

Today's prevalence of obesity is dramatically increasing and a two-way interaction between higher body mass index (BMI) and oral health is described in scientific litterature. Accordingly, the present study was aimed to evaluate the relation of BMI and oral health indicators. In this cross-sectional study, 240 individuals according to their BMI were placed in the following experimental groups; underweight (BMI<18), normal weight (18≤BMI≤24.9), overweight (25≤BMI≤29.9) and obese (30≤BMI). Plaque index (PI), gingival index (GI), bleeding on probing (BOP) and decayed, missed and filled teeth (DMFT) were obtained. Data was analyzed by SPSS 26 using descriptive tests and one-way ANOVA at the level of 0.05. The mean age and sex distribution of participants of experimental groups had no significant difference (p>0.05). GI and BOP were significantly lower in normal weight persons than individuals with high BMI (p<0.05). DMFT, the number of decayed, missed and filled teeth was approximately similar in all experimental groups (p>0.05). Pearson correlation coefficient showed a positive significant relation between GI as well as BOP with BMI (p=0.000). Based on the results achieved by the present study, although periodontal health status of overweight and obese individuals was significantly compromised compared to normal weight persons, the dental health status was not affected by BMI.

Association between Body Mass Index (BMI) and Dental Caries among 6-12-Year-Old School Children

This study aimed to identify the association between BMI and dental caries in 6−12-year-old children. This cross-sectional study was carried out among 6−12-year-old school children and their parents. The data on Body Mass Index (BMI) and dental caries for study participants were included in the study. The association between BMI and dental caries was evaluated using SPSS software. The study comprises 400 school children (157 boys and 243 girls) aged an average of 8.9 years. The overall prevalence of dental caries was 84% in primary dentition and 75% in permanent dentition, with a mean DMFT and dmft (decayed, missing and filled teeth) of 2.85 and 5.48, respectively. There was a significant association witnessed between mothers’ education and BMI status. A significant association was also evident between decayed (d), missing (m) and filled (f) teeth and overall dmft with different BMI categories (p < 0.05). There was no significant association evident between DMFT and each category of BMI (p > 0.05). The dmft and DMFT within the four BMI categories by one-way ANOVA were highly significant (p < 0.001). Post hoc analysis helped us identify the relationship among the various categories of BMI with dental caries. There was a positive association evident between the BMI of the children and dental caries.

Association between gastric reflux, obesity and erosive tooth wear among psychiatric patients

The prevalence of erosive tooth wear and obesity are high in psychiatric patients and soft drink consumption is a common risk factor associated with both diseases. This study aimed to assess the association between soft drink consumption, gastric reflux, erosive tooth wear, and obesity among resident patients at the Psychiatric Hospital, Taif, Saudi Arabia.This descriptive, cross-sectional study included 223 adult psychiatric inpatients (126 male, 97 female) with a mean age of 42.3 years (± 2.2). Dental erosion detection was performed according to World Health Organization criteria. The medical evaluation included assessment of the body mass index (BMI). With appropriate sample weighting, relationships between erosive tooth wear, gastric reflux, and obesity were assessed using multivariable logistic regression.Ninety eight patients (43.9%) presented with erosive tooth wear. The mean BMI for the entire study population was 27.7 ± 6.3 kg/m2. Regression analysis showed a strong association between erosive tooth wear and chronic vomiting or bulimia (adjusted odds ratio = 2.11; 95% confidence interval [CI] = 1.98-5.07, P < .001), gastric reflux (adjusted odds ratio = 2.13; 95% CI = 1.34-6.23, P < .001), consumption of soft drinks (adjusted odds ratio = 2.14; 95% CI = 1.03-6.08, P < .001), and schizophrenia and delusional disorders (adjusted odds ratio = 2.07; 95% CI = 1.98-5.08, P < .001).This study demonstrates a significant association between erosive tooth wear prevalence and chronic vomiting or bulimia, consumption of soft drinks, and gastric reflux among resident patients at psychiatric hospital.

Age at first childbirth in relation to oral health later in life

OBJECTIVE

This study aimed to examine the relationship between age at first childbirth and oral health. The mediation effect of body mass index (BMI) on this relationship was also determined.

METHODS

This study analyzed data of 2,506 parous postmenopausal women aged 50 or older from the Korea National Health and Nutrition Examination Survey 2013-2015. Chewing inconvenience was investigated by an oral interview. Periodontitis and dental caries were determined through dental examinations. Multivariable logistic regression analysis was performed to examine the relationship between age at first childbirth and oral health, and mediation analysis was performed to examine the contribution of BMI on the relationship between age at first childbirth and oral health.

RESULTS

Women who underwent their first delivery between the age of 26 and 46 years had significantly decreased odds of chewing inconvenience (odds ratio [OR] = 0.72, 95% confidence interval [95% CI] = 0.56-0.93, P = 0.010) compared with the odds of those women whose first delivery was between at the age of 15 and 22 years. We also found a significant linear relationships between age at first childbirth and odds of chewing inconvenience (OR = 0.83, 95% CI = 0.74-0.95, P = 0.017) and dental caries (OR = 0.84, 95% CI = 0.74-0.96, P = 0.025). BMI accounted for 12.9% of the relationship between age at first childbirth and dental caries. Age at first childbirth was only indirectly associated with periodontitis through BMI (OR = 0.98, 95% CI = 0.96-0.99, P = 0.003).

CONCLUSIONS

Women whose first delivery occurred at a young age had significantly increased odds of chewing inconvenience and dental caries. BMI mediated the relationships between age at first childbirth and periodontitis and dental caries.

Mental health research studies in Saudi Arabia for the years 2009-2019; a systematic scoping review

BACKGROUND

An updated systematic scoping review and narrative analysis of all possible mental health studies done during the concerned immediate years clarifies its present condition and status for all professionals, and concerned researchers.

AIMS

To synthesize published mental health research studies in and for Saudi Arabia for the years 2009-2019 with the confidence to evaluate current situation, identify research gaps and limitations (if any), and assist in conceptualizing the forthcoming directions of future mental health research activities.

METHODS

Scoping systematic review and modified narrative analysis were the methods utilized to achieve the aim and objective set for this formal academic endeavor.

RESULTS

Of the 1006 published studies identified from chosen databases, a total of 241 papers were included and had passed the stringent criteria set for the scoping review process. Basic characteristics of the reviewed studies were quantitative survey type with about 101-500 size range of respondents, utilizing non-patients and adults for participants which were common and randomly chosen from selected population, and most research activities were self-funded. Four major research themes were found including a list of research limitations.

CONCLUSIONS

This systematic scoping review identified a wide range of results characterizing the different studies that qualified using pre-determined inclusion-exclusion criteria. Though of increasing publication volume in the past decade, most researches done were quantitative survey type whose themes seemed to show no drastic difference or change from the previous years of output. More variety in research themes would further improve the over-all quality of mental health publications.

Knowledge, Attitudes and Practices Regarding Oral Health and Oral Care Among Nursing Staff at a Mental Health Hospital in Taif, Saudi Arabia: A Questionnaire-based Study

Background and Aim:

Nurses are the principal oral healthcare providers for hospitalized patients. The purpose of this study was to assess the knowledge, attitudes, and practices of nurses at a mental health hospital in Saudi Arabia regarding oral health care of the hospitalized patients.

Materials and Methods:

A cross-sectional survey design was used in which 247 nursing staff completed a questionnaire that collected sociodemographic information, knowledge, and practices regarding oral health maintenance of patients and their attitudes toward oral health care of psychiatric patients. The chi-square and Kruskal-Wallis H tests were used to examine group differences.

Results:

A total of 247 (136 males and 111 females) nursing staff were involved in the survey with the mean age of 26 ± 32 years. Results showed significant gender differences in knowledge and practices, but no gender differences in attitudes. Male nurses were more likely to look at teeth and gums for signs of a healthy mouth (male = 97.8%, female = 95.5%, P = .04), used toothpaste to clean the patient’s teeth (male = 52.9%, female = 50.5%, P = .03), and believed that HIV/AIDS patients are at risk of developing oral health problems (male = 50.7%, female = 43.2%, P = .04). Nurses had more knowledge than nurse technicians regarding gum disease and dental abscesses ( P = .0001). Nursing staff with over five years of experience were more likely to agree about the need for the oral health care of hospitalized patients.

Conclusion:

The results emphasize the need for training of healthcare workers about the importance of oral health and considering oral health care as a patient’s rights rather than privilege.

Association between body mass index and dental caries in the Kingdom of Saudi Arabia: Systematic review

OBJECTIVE

The Kingdom of Saudi Arabia (KSA) has one of the highest prevalence of both obesity and dental caries. To date, there has not been any documented evidence linking these two factors. Therefore, the objective was to conduct a systematic review of published studies that have analysed the association between body mass index and dental caries in the KSA for both children and adults.

METHODS

A systematic database search [PubMed, EMBASE, Web of Science, CINAHL and Cochrane Library] was conducted following the PRISMA guidelines. The inclusion criteria were observational studies, with no limit on the publication date. Search terms included: dental caries, obesity, overweight, body mass index, BMI 'AND' Saudi Arabia. The independent variable was body mass index (BMI), and the primary outcome measure was dental caries prevalence and severity.

RESULTS

From 951 search results, 935 citations were identified and excluded. Of the 16 potentially eligible studies, two citations were excluded, because the studies did not meet the inclusion criteria. This left fourteen studies meeting the criteria to be included in this systematic review. Ten studies outlined children, and four studies assessed adults. For children, two studies resulted in a positive association between high BMI and caries, six studies resulted in a negative association, and two studies had a non-significant association. For adults, two studies resulted in a positive association between high BMI and dental caries, and two studies had a non-significant association. These were rated as having low to moderate risk of bias.

CONCLUSION

As a result of this equivocal outcome within the systematic review, body mass index and dental caries present as a complex association. Further long-term studies are required to translate the findings into clinical practice.

Dentists' perspectives on barriers to providing oral health care in French psychiatric hospitals with on-site dental clinics

OBJECTIVES

Psychiatric inpatients suffer from poorer oral health than the general population, and difficulties in accessing necessary dental treatment remain even when a dedicated dental service is available within the psychiatric hospital. The aim of this study was to identify barriers to access dental care from the point of view of dentists working within French psychiatric hospitals.

METHODS

The relatively small number of dentists working in psychiatric hospitals necessitated a qualitative approach. Semi-structured interviews were conducted, recorded, transcribed and coded in a conventional content analysis approach.

RESULTS

Eight interviews were conducted. Six of the dentists interviewed were men, and two were women. Three of them worked full-time in a psychiatric facility, while the other five worked partly in the hospital and partly in private practice. The average duration for interviews was 54 minutes (minimum 24 min, maximum 89 min). The interviews highlighted three dimensions of barriers to access to dental care. The first dimension was directly related to the patient. This may be linked to the patient's psychiatric disorder but not necessarily. This also encompasses refusal of care. A second dimension regrouped events related to the organization of the hospital (locally), such as communication issues between staff members within the dental office, and with other staff members from the psychiatric ward. A third dimension included difficulties related to the overall organization of the healthcare system, including financial issues and deinstitutionalization.

CONCLUSIONS

In-site dental consultations appear as an interesting tool to enhance access to oral care for psychiatric inpatients. However, difficulties remain from the dentists' perspective.
