Oral health condition and occurrence of depression in the elderly

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

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

Depression Symptoms Linked to Multiple Oral Health Outcomes in US Adults

BACKGROUND

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

OBJECTIVE

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

METHODS

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

RESULTS

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

CONCLUSION

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

KNOWLEDGE TRANSFER STATEMENT

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

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

PURPOSE

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

METHODS

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

RESULTS

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

CONCLUSION

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

Emotional symptoms, dietary patterns and dental caries: A cross-sectional study in adolescents

OBJECTIVES

This study investigates the relationship between emotional symptoms and dental caries in adolescents and the role of dietary patterns as mediating variables.

METHODS

This cross-sectional study used a multistage stratified random sample of schools, in Jiangsu, with a sample of 17,997 adolescents aged 11-19. Measures included emotional symptoms, dental caries, toothbrushing frequency, and dietary patterns. Logistic and Poisson regression models were conducted to test mediation hypotheses.

RESULTS

The decayed, missing, and filled teeth index (DMFT) was related to depressive symptoms following adjustment for other variables (incidence rate ratios [IRR] = 1.09; p < 0.05), but not to anxiety symptoms level (IRR = 1.02; p > 0.05). The link between depressive symptoms and DMFT had a partial mediation impact on toothbrushing frequency (a, b, c' all p < 0.05). Sugary foods, but not fried foods, partially mediated the link between depressive symptoms and caries when toothbrushing frequency was adjusted.

CONCLUSION

There are direct and indirect associations between emotional symptoms and caries; the latter may be due to changes in oral health behaviours that increase the risk of caries.

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

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

Mental health screening and referral to treatment in dental practices: A scoping review

OBJECTIVE

The purpose of this study was to conduct a scoping review to examine and summarize the characteristics of research related to mental health (MH) screenings and/or referrals to treatment in dental practices.

METHODS

We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for Scoping Reviews and searched multiple databases for terms connected with dental care, MH concerns, screening, and referral. Included articles: (1) described care provided in a dental practice, (2) described a situation where the patient is experiencing the potential MH problem, (3) did not involve dental anxiety exclusively, and (4) involved some form of MH screening and/or referral to treatment. Article analysis included a summary of key study characteristics, types of evidence, study design, and central concepts and definitions.

RESULTS

The search generated 2050 records, with 26 ultimately included. Most studies involved only adults (22, 85%), but only three (12%) reported on rurality (two urban; one mixed) and only two each (8%) reported race or ethnicity. Fifteen (58%) articles were prospective and 11 (42%) were retrospective. The studies varied widely in study designs, from 11 (42%) cross-sectional methodologies to only one (4%) randomized controlled trial. Thirty-four screening tools were used to screen for symptoms of 43 MH conditions, with depression and anxiety screened for most frequently. Few articles discussed making referrals, practice workflows, or follow-up outcomes.

CONCLUSIONS

Included studies provide evidence of viable options for dental practitioners regarding MH screening, referring, and conducting follow-up, but lack specificity regarding these processes. Overall, more research is needed to clarify what workflows are most efficient for dental practitioners and efficacious in identifying patients with MH concerns.

Association between intrinsic capacity and oral health in older patients in a frailty clinic

PURPOSE

This study aimed to investigate how intrinsic capacity (IC) deficit is associated with oral functional decline.

METHODS

This cross-sectional study enrolled older adults at a research hospital frailty clinic between July 2021 and May 2023. IC evaluation included the locomotion, cognition, vitality, psychology, and sensory domains. Criteria for deficits were established within each domain, and the number of IC deficit domains was calculated for each patient. Oral function assessment included oral hygiene, oral dryness, occlusal force, tongue-lip motor function, tongue pressure, masticatory function, and swallowing function. Patients who met three or more criteria were classified into the oral hypofunction (OHF) group. Univariate and multivariate logistic regression analyses were performed to investigate the relationship between IC deficit and OHF.

RESULTS

Of 222 included patients (mean age 78.3 ± 6.3 years; 39.6% men), 105 (47.3%) met the criteria for OHF. This OHF group showed a significantly higher prevalence of locomotion, cognition, psychology, and sensory domain deficits than the normal oral function group. Multivariate analysis adjusted for age and sex revealed a significant association between IC deficits and OHF (odds ratio [OR], 1.33; 95% confidence interval [CI] 1.04-1.70). A significant association was also observed between the locomotion domain and OHF (OR, 2.06; 95% CI 1.13-3.76).

CONCLUSION

This study highlights the potential relationship between the number of IC domain deficits and oral functional decline, with the most significant domain being locomotion. Furthermore, it suggests a possible link between sensory and oral function.

Occurrence of Depression and its Association with Oral Health in Elderly People Living in Old Age Homes of Mathura

Introduction

Depression can affect oral health as a result of neglecting oral hygiene procedures which leads to an increased risk of dental caries and periodontal disease.

Aim

To determine relationship between oral health and depression among elder people residing in old age homes of Mathura city.

Materials and Methods

The study was conducted among 500 subjects aged ≥60 years where dental condition, number of missing teeth, removable denture wearing, teeth mobility, periodontal condition, pocket depth, loss of attachment, and depression according to the Patient Health Questionnaire-9 scale were assessed.

Results

Regression analysis showed a positive relationship of the PHQ-9 value with DMFT and MT.

Conclusion

Among people aged 60 years and over, severity of depression increased with higher number of MT and DT.

Oral health-related quality of life and depressive symptoms in adults: longitudinal associations of the English Longitudinal Study of Ageing (ELSA)

BACKGROUND

Little is known about the relationship between oral health status and depressive symptoms in adults in England. The aim of this study was to examine the longitudinal association between oral health parameters and depressive symptoms in adults in England.

METHODS

Data were obtained from the English Longitudinal Study of Aging (ELSA), which included information on self-rated oral health, oral impairment in daily life (Oral Impacts on Daily Performances, OIDP), and depressive symptoms (Center for Epidemiologic Studies Depression Scale, CES-D) in 6790 adults aged ≥ 50 years. Wave 3 data were used as baseline, while Waves 5 and 7 were used for follow-up assessments. Logistic regression was used to determine whether depressive symptoms at baseline anticipated self-rated oral health and OIDP and whether oral health status (at baseline) was associated with the development of depressive symptoms at follow-up assessment.

RESULTS

Participants with poor self-rated oral health were at higher risk of developing depressive symptoms, even after adjusting for behavioral, clinical, and sociodemographic characteristics (OR = 1.69, 95% CI 1.38-2.07). Similarly, having oral impacts on daily performances were associated with the development of depressive symptoms: The OR for developing depressive symptoms at Wave 5 or 7 was 2.19 (95% CI 1.62-2.96) after adjustment for all covariates. Participants with depressive symptoms at baseline were more likely to report poor self-rated oral health (OR = 1.93, 95% CI 1.52-2.44) or one or more oral impacts (OR = 1.86, 95% CI 1.45-2.40) at follow-up than those without depressive symptoms at baseline, even after adjusting for confounders.

CONCLUSIONS

In the present study, a bidirectional association was found between depressive symptoms and poor oral health in older adults. Maintaining good oral health in older adults may be a protective factor against depressive symptoms. Therefore, more attention should be paid to promoting oral health awareness in older adults, including encouraging regular dental checkups, proper toothbrushing and flossing techniques, and healthy lifestyles.

Chewing ability and associated factors in older adults in Germany. Results from GEDA 2019/2020-EHIS

BACKGROUND

Oral well-being is an important component of general well-being and quality of life, as it is greatly influenced by the ability to chew and speak, and thus by central factors of social interaction. Because quality of life and participation are important factors for health in older age, the aim of this article was to examine the chewing ability, including associated factors, for the older population in Germany on the basis of a nationally representative sample.

METHODS

Database is the German Health Update (GEDA 2019/2020-EHIS), a population based cross-sectional survey of the Robert Koch Institute. In the telephone interview, participants aged 55 years and older were asked: "Do you have difficulty biting and chewing on hard foods such as a firm apple? Would you say 'no difficulty', 'some difficulty', 'a lot of difficulty' or 'cannot do at all/ unable to do'?" Prevalences and multivariate prevalence ratios (PR) were calculated with 95% confidence intervals (95% CI) from log-Poisson regressions. Sociodemographic, health-, behavioral- and care-related characteristics were investigated as associated factors.

RESULTS

The analyses were based on data from 12,944 participants (7,079 women, 5,865 men). The proportion of people with reduced chewing ability was 20.0%; 14.5% had minor difficulty, 5.5% had major difficulty. There were no differences between women and men. The most important associated factors for reduced chewing ability were old age (PR 1.8, 95% CI 1.5-2.1), low socioeconomic status (PR 2.0, 95% CI 1.7-2.5), limitations to usual activities due to health problems (PR 1.9, 1.6-2.2), depressive symptoms (PR 1.7, 1.5-2.1), daily smoking (PR 1.6, 95% CI 1.3-1.8), low dental utilization (PR 1.6, 95% CI 1.4-1.9), and perceived unmet needs for dental care (PR 1.7, 95% CI 1.5-2.1).

CONCLUSIONS

One fifth of adults from 55 years of age reported reduced chewing ability. Thus, this is a very common functional limitation in older age. Reduced chewing ability was associated with almost all investigated characteristics. Therefore, its prevention requires a holistic view in the living environment and health care context of older people. Given that chewing ability influences quality of life and social participation, maintaining or improving chewing ability is important for healthy aging.

Dietary Habits and Oral Hygiene as Determinants of the Incidence and Intensity of Dental Caries-A Pilot Study

OBJECTIVES

The aim of this study was to assess the influence of dietary and hygiene habits on the prevalence and intensity of dental caries. A group of 148 adults participated in the study.

METHODS

A self-administered nutrition and oral hygiene questionnaire was used to assess dietary habits and oral hygiene routine. A preventive diet index (PDI), a cariogenic diet index (CDI), and an oral health hygiene and prevention index (OHHPI) were created based on part of the questions. The intensity of dental caries among the respondents was investigated by the decayed, missing, and filled teeth index (DMFT), which was estimated on the basis of data obtained during the dental examination.

RESULTS

The study showed that 97% of the respondents had filled carious cavities, while untreated carious cavities were observed in up to 78% of the study participants. The respondents had an average consumption of preventive products and a low consumption of caries-stimulating foods. The preventive dietary index (PDI) value was higher in the female group than in the male group. A more frequent consumption of caries-inhibiting products was demonstrated by those declaring that they took various types of dietary supplements. The use of health-promoting sugar substitutes by the respondents was associated with a lower intensity of dental caries and a more frequent consumption of preventive products.

CONCLUSIONS

The analysis of the survey results indicates the need to implement educational activities aimed at increasing public awareness of the prevalence of dental caries among adults.

Understanding the health benefits and technological properties of β-glucan for the development of easy-to-swallow gels to guarantee food security among seniors

The world's population is growing rapidly and the number of elderly people with undernutrition and malnutrition is increasing. Common health problems among seniors are cardiovascular, inflammatory, gastrointestinal, and cognitive disorders, cancer, diabetes, psychological and dental problems. The food industry is trying to meet the demands of an aging society, but these efforts are not sufficient. New strategies are needed, and they demand foods development with modified textures that are easy to swallow, such as gels suitable for seniors. Depending on the specific needs of the elderly, bioactive compounds with health benefits should be included in food systems. Novel foods may play an important role in the prevention, maintenance, and treatment of age-related diseases. One of the most studied bioactive compound is β-glucan, a polysaccharide with approved health claims confirmed by clinical trials, such as "β-glucan contributes to the maintenance of normal blood cholesterol levels" and "the consumption of β-glucan from oats or barley contributes to the reduction of postprandial glucose spikes." In this review, the health benefits, and technological properties of β-glucan for the development of senior-friendly ready-to-swallow gels were described. In addition, some patents and studies conducted in connection with the development of the gel systems were collected.

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

OBJECTIVES

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

CLINICAL RELEVANCE

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

Anxiety and depression in keratotic oral lichen planus: a multicentric study from the SIPMO

OBJECTIVES

Oral lichen planus with exclusive keratotic reticular, papular, and/or plaque-like lesions (K-OLP) is a clinical pattern of OLP that may be associated with a complex symptomatology and psychological alteration. The aim of the study was to evaluate the prevalence of anxiety (A) and depression (D) in patients with K-OLP, analyzing the potential predictors which can affect mental health status.

METHODS

Three hundred K-OLP patients versus 300 healthy controls (HC) were recruited in 15 Italian universities. The Numeric Rating Scale (NRS), Total Pain Rating Index (T-PRI), and Hamilton Rating Scales for Depression and for Anxiety (HAM-D and HAM-A) were administered.

RESULTS

The K-OLP patients showed statistically higher scores in the NRS, T-PRI, HAM-D, and HAM-A compared with the HC (p-value < 0.001**). A and D were found in 158 (52.7%) and 148 (49.3%) K-OLP patients. Strong linear correlations were identified between HAM-A, HAM-D, NRS, T-PRI, and employment status and between HAM-D, HAM-A, NRS, T-PRI, employment status, and female gender. Multivariate logistic regression revealed that HAM-D and HAM-A showed the greatest increase in the R2 value for A and D in the K-OLP patients, respectively (DR2 = 55.5% p-value < 0.001**; DR2 = 56.5% p-value < 0.001**).

CONCLUSIONS

The prevalence of A and D is higher in the K-OLP patients compared with the HC, also found in K-OLP subjects without pain, suggesting that the processing of pain may be in a certain way independent of the processing of mood.

CLINICAL RELEVANCE

Mood disorders and pain assessment should be carefully performed in relation to K-OLP to obtain a complete analysis of the patients.

Association Between Changes in Oral Health-Related Quality of Life and Depressive Symptoms in the Korean Elderly Population

Objectives: The aim of this study was to examine the association between changes in oral health related quality of life (OHRQoL) and depressive symptoms in the elderly South Koreans.

Methods: We used the 2018 and 2020 Korean Longitudinal Study of Ageing data. Our study population was a total of 3,604 participants aged over 65 in 2018. The independent variable of interest was the changes in the Geriatric Oral Health Assessment Index as OHRQoL between 2018 and 2022. The dependent variable was depressive symptoms in 2020. Multivariable logistic regression analyzed the associations between changes in OHRQoL and depressive symptoms.

Results: Participants with improvement in OHRQoL over 2-year period were likely to have fewer depressive symptoms in 2020. Especially, changes in the oral pain and discomfort dimension score was associated with depressive symptoms. A decline in oral physical function, such as difficulty in chewing and speaking, was also associated with depressive symptoms.

Conclusion: Negative change in OHRQoL is a risk factor for depression in elderly. This results suggest the importance of maintaining good oral health in later life, as a protective factor against depression.

Relationship between Cognition, Depression, and Oral health status in Older adults: A longitudinal cross-lagged analysis

BACKGROUND

The world's population is aging increasingly, and older adults' physical and mental health needs to be prioritized. Although several studies have explored the relationship between cognition, depression, and oral health in older adults, the exact nature and direction of this relationship are poorly understood. Moreover, most studies to date have been cross-sectional, with fewer longitudinal studies. The current longitudinal study explored the relationship between cognition, depression, and oral health in older adults.

METHODS

We used data from two waves (2018, 2020) of the Korean Longitudinal Study of Aging, which included 4543 older adults aged 60 years and older. General socio-demographic characteristics were analyzed using descriptive analysis, and study variables were described using t-tests. Generalized Estimating Equations (GEE) and cross-lagged models were used to examine the longitudinal associations between cognition, depression, and oral health.

RESULTS

The GEE results suggested that better cognition and less depression over time were associated with better oral health in older adults. Cross-lagged models further validated the effect of depression on oral health over time.

LIMITATIONS

The directionality of the influence of cognition on oral health could not be determined.

CONCLUSIONS

Although there were several limitations, our study provided novel ideas for verifying the effects of cognition and depression on oral health in older adults.

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

AIM

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

New horizons in understanding oral health and swallowing function within the context of frailty

Frailty is a complex and multidimensional condition wherein declines in physiologic reserve and function place individuals in a state of heightened vulnerability and decreased resiliency. There has been growing interest in both research and clinical settings to understand how to best define, assess and characterise frailty in older adults. To this end, various models and clinical assessment tools have been used to define and measure frailty. While differences exist among these models and tools, a common unifying theme is a focus on physical function and activity. Notably absent across many available conceptual models and clinical tools are items directly related to oral and swallowing function. This is an important oversight as widespread changes to both oral and swallowing function are evident in older adults. Indeed, emerging evidence suggests many of the functional domains affected in frail older adults, such as nutrition and sarcopenia, have cyclical relationships with impairments in oral (oral hypofunction) and swallowing function (dysphagia) as well. The increasing appreciation for the interrelationships among oral hypofunction, dysphagia and frailty provides an opportunity for refinement of frailty assessment and characterisation in older adults to incorporate metrics specific to oral and swallowing function.

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

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

Prevalence of periodontitis in dentate people between 2011 and 2020: A systematic review and meta-analysis of epidemiological studies

AIM

The aim of the study was to evaluate the prevalence of periodontitis in dentate people between 2011 and 2020.

MATERIALS AND METHODS

PUBMED, Web of Science, and LILACS were searched up to and including December 2021. Epidemiological studies reporting the prevalence of periodontitis conducted between 2011 and 2020 were eligible for inclusion in this review. Studies were grouped according to the case definition of confidence as confident (Centers for Disease Control [CDC] AAP 2012; CDC/AAP 2007; and Armitage 1999) and non-confident (community periodontal index of 3 or 4, periodontal pocket depth >4 mm, and clinical attachment level ≥1 mm). Random effects meta-analyses with double arcsine transformation were conducted. Sensitivity subgroup and meta-regression analyses explored the effect of confounding variables on the overall estimates.

RESULTS

A total 55 studies were included. The results showed a significant difference, with confident case definitions (61.6%) reporting nearly twice the prevalence as non-confident classifications (38.5%). Estimates using confident periodontal case definitions showed a pooled prevalence of periodontitis of 61.6%, comprising 17 different countries. Estimates reporting using the CDC/AAP 2012 case definition presented the highest estimate (68.1%) and the CDC/AAP 2007 presented the lowest (48.8%). Age was a relevant confounding variable, as older participants (≥65 years) had the highest pooled estimate (79.3%).

CONCLUSION

Between 2011 and 2020, periodontitis in dentate adults was estimated to be around 62% and severe periodontitis 23.6%. These results show an unusually high prevalence of periodontitis compared to the previous estimates from 1990 to 2010.

Questionnaire-free machine-learning method to predict depressive symptoms among community-dwelling older adults

The 15-item Geriatric Depression Scale (GDS-15) is widely used to screen for depressive symptoms among older populations. This study aimed to develop and validate a questionnaire-free, machine-learning model as an alternative triage test for the GDS-15 among community-dwelling older adults. The best models were the random forest (RF) and deep-insight visible neural network by internal validation, but both performances were undifferentiated by external validation. The AUROC of the RF model was 0.619 (95% CI 0.610 to 0.627) for the external validation set with a non-local ethnic group. Our triage test can allow healthcare professionals to preliminarily screen for depressive symptoms in older adults without using a questionnaire. If the model shows positive results, then the GDS-15 can be used for follow-up measures. This preliminary screening will save a lot of time and energy for healthcare providers and older adults, especially those persons who are illiterate.

The association between the number of teeth and frailty among older nursing home residents: a cross-sectional study of the CLHLS survey

BACKGROUND

Given that few studies have explored the association between oral health and frailty among older nursing home residents, the purpose of this study was to assess the association between oral health (i.e., the number of teeth and oral behaviors) and frailty in this population using the Chinese Longitudinal Healthy Longevity Survey (CLHLS).

METHODS

This was a national cross-sectional study derived from the seventh wave of CLHLS in 2018, consisting of 365 older nursing home residents aged 65 years or older. The frailty index was constructed based on 32 variables consisting of self-rated health status, anxiety, depression, ADL and IADL. Oral health was measured through the number of natural teeth and tooth brushing behavior. Multiple logistic regression was used to identify this association between the number of teeth, oral health behaviors, and frailty.

RESULTS

The mean age of this sample was 87.6 (SD = 9.5), with 154 (42.2%) males. The prevalence of frailty and edentulism was 71.2% and 33.4%, respectively. Multiple logistic regression analysis found that the likelihood of frailty decreased with an increased number of teeth, with an OR of 0.94 (95% CI: 0.91-0.98). Compared with participants with edentulism, older adults with 1 to 20 teeth had a lower likelihood of frailty (OR = 0.39, 95% CI: 0.17-0.88); these results were also found in older adults with more than 20 teeth (OR = 0.20, 0.07-0.57). Additionally, older adults who brush their teeth regularly have a lower likelihood of frailty than those who never brush their teeth (OR = 0.37, 95% CI: 0.13-0.99).

CONCLUSION

Older nursing home residents who maintain their natural teeth can help lower the risk of frailty, and regular toothbrushing also contributes to decreasing the risk of frailty. Our study emphasizes the importance of oral health, and cohort studies with large-scale samples to address this important issue are warranted in the future.

Predictors of Depression among Individuals Receiving the Basic Livelihood Security Program Benefits in Korea: A Study Based on the Sixth and Seventh Korea National Health and Nutrition Examination Survey (2013-2018)

The purpose of this study is to verify the relationship between oral health behaviors and depression and influencing factors on depression to establish strategies that can contribute to improvement of mental health problems such as depression in vulnerable social class recipients. This study is a descriptive correlation study conducted on basic livelihood recipients over the age of 19 who responded to the 6th~7th (2013~2018) National Health and Nutrition Examination Survey. In this study, a total of 2749 people who met the criteria for subject selection were included in final analysis after requesting and downloading their raw data from the National Health and Nutrition Examination Survey through the consent process mandated by the Korea Centers for Disease Control and Prevention. Of the 2749 subjects, 279 were diagnosed with depression, accounting for 10.1% of the total. The collected data were analyzed using t-tests and chi-squared tests, and factors affecting depression were analyzed by logistic regression analysis. Our results showed that the factors affecting depression were 1.74 times for men (95% CI = 1.29-2.24), 1.37 times for older people (95% CI = 1.01-1.87), and 1.66 times for low education (95% CI = 1.21-2.27). Subjects with impairment in daily activities had 1.89 times (95% CI = 1.43-2.52) higher risk. Subjects with moderate physical activity and subjects with economic activity showed a lower risk (95% CI = 0.30-0.73) and 0.52 times (95% CI = 0.30-0.72), respectively, than subjects who did not. We confirmed that the probability of being diagnosed with depression decreased, and the perceived health status was 0.36 times lower (95% CI = 0.22-0.61) than those with good status. Therefore, it is necessary to prepare countermeasures that reflect various aspects in consideration of not only age and gender, but also daily life and emotional state when establishing policies for vulnerable classes such as recipients of basic livelihood.

Effect of mechanical instrumentation with adjunct photodynamic therapy on salivary TNFα levels and clinical periodontal and peri‑implant status in patients with depression: A randomized controlled trial

INTRODUCTION

The aim of the present randomized controlled trial was to assess the effect of mechanical instrumentation (MI) with adjunct photodynamic therapy (PDT) on salivary tumor necrosis factor-alpha (TNFα) levels and clinical periodontal and peri‑implant status in patients with depression.

MATERIALS AND METHODS

In groups 1 and 2, individuals with periodontal and peri‑implant diseases with and without depression, respectively were included. Group-3 comprised of systemically healthy individuals with a healthy periodontal and peri‑implant status. In groups 1 and 2, patients in the test- and control groups received MI with and without PDT respectively. Periodontal and peri‑implant probing depth and plaque and gingival indices were measured. Radiographic evaluation was done at baseline. Whole salivary tumor necrosis factor alpha (TNFα) in peri‑implant sulcular fluid were measured at baseline. The clinical and immunological parameters were reassessed at 120 days' follow-up. Level of significance was set at P<0.05.

RESULTS

Thirty-four, 36 and 37 implants were in function in groups 1, 2 and 3, respectively. At baseline, periodontal and peri‑implant clinical parameters and TNFα levels were significantly higher in groups 1 (P<0.05) and 2 (P<0.05) than Group-3. At 4-months follow-up, there was no difference in periodontal and peri‑implant clinical parameters in the test- and control groups among individuals in groups 1 and 3. In Group-2, there was a significant reduction in periodontal (P<0.05) and peri‑implant (P<0.05) clinical parameters at 4-months follow-up than baseline. In Group-2, there was no significant difference in these parameters among patients in the test- and control-groups.

CONCLUSION

In patients with depression clinical periodontal and peri‑implant status is poorer and salivary TNFα levels are higher after MI with or without PDT. In healthy patients, PDT offers no additional benefits in the treatment of periodontal inflammation.

Selective serotonin reuptake inhibitors as a risk factor for dental implant failure: a retrospective clinical study

The trend in recent decades in Europe and the United States points to an exponential increase in the consumption of antidepressant drugs and, in particular, selective serotonin reuptake inhibitors (SSRIs). This retrospective study aimed to investigate whether there is an association between SSRI intake and dental implant (DI) failure or survival and, secondarily, to investigate the influence of other systemic and local factors. This retrospective cohort study was done in accordance with the the STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) guidelines for observational studies. A total of 170 patients received 573 DIs between 2014 and 2020.The reported DI failure rate was 6.11% (n = 35 DIs). Of these 18.31% failed in patients treated with SSRIs while 4.38% failed in patients who were not prescribed SSRIs (p < 0.001). Specifically, use of these drugs was associated with a hazard ratio rate of DI failure that was 4.53 times higher (95% CI: 1.93 to 10.61), and in the multivariate analysis, a 3.70 times higher adjusted risk was found. A lower DI survival rate at 90 months' follow up was also observed in these patients compared with those not taking them (84.30% vs 96%, respectively; p = 0.00014). With the limitations of the present study it can be affirmed that there is a relation between the intake of SSRIs and DI failure, as well as a lower survival rate in these patients.

Oral health and depressive symptoms among older adults in urban China: a moderated mediation model analysis

Background

This study explored the association between oral health and depression occurs via daily dietary satisfaction as a mediator, and that body mass index could moderate the path between daily dietary satisfaction and depression.

Methods

Data for this research were derived from a community survey adopting quota sampling in the cities of Tianjin and Shijiazhuang in mainland China in 2020 (N = 781). The moderated mediation model was tested by using bootstrapping with resampling strategies, and the Johnson-Neyman technique was used to visualize the moderating effect of body mass index.

Results

A significant negative association between oral health and depression has been indicated (B = −0.22, SE = 0.11, 95%CI [− 0.44, − 0.01]), and dietary satisfaction partially mediated the relationship between oral health and depression (B = −0.04, SE = 0.02, 95%CI [− 0.09, − 0.002]). The path was moderated by body mass index, and the effect of dietary satisfaction on depression was much greater in people with relatively low body mass index.

Conclusions

This study present evidence for policymakers and researchers that strategies to enhance oral health and daily dietary satisfaction could be important for preventing depression in Chinese older adults, and especially for the relatively fitter older groups with lower body mass index.

Inclusion of gerodontology in dental curriculum: An urgent case for India

The proportion of older adults is on the rise. Management of dental problems in this group is different from the general population, and hence requires special training. Gerodontology is yet to find its place in the Indian dental curriculum. A lack of training would result in inadequate care delivery. In this article, we share our views on the need for inclusion of the subject, potential challenges, and a guide for incorporation of gerodontology in undergraduate and postgraduate curriculum in the Indian dental institutes. We propose a framework based on the salient features of Kern's 6-step approach for curriculum development and Kotter's 8-step change management model. Some features are common to both the models. A combination of these models includes the following salient features: Problem identification and general needs assessment, beginning with a sense of urgency and targeted needs assessment, communication of the vision for change, working in guided coalitions and defining clear goals and objectives, adopting the relevant educational strategies, implementation strategies to enable change and generating short-term wins, evaluating the effectiveness of the curricular reform and sustaining and anchoring the change. The proposed framework may also be useful for countries where gerodontology is yet to be implemented.

Association between Bone-Related Physiological Substances and Oral Function in Community-Dwelling Older People

BACKGROUND

Oral dysfunction is related to long-term cares including activities of daily living. The objective of this study was to determine the association between oral function and the bone-related physiological substances osteocalcin (OC) and insulin-like growth factor-1 (IGF-1).

METHODS

The study participants were 139 community-dwelling older people in Japan. Evaluation of oral dysfunction was based on subjective judgment by each participant. Blood analysis included OC, IGF-1, and albumin.

RESULTS

Univariate and multiple logistic analyses showed that IGF-1 was significantly associated with a "decline in masticatory function" (p = 0.0074 and p = 0.0308, respectively). Receiver operating characteristic curve analysis of IGF-1 levels revealed a threshold score of 108 ng/mL (p < 0.01) for discriminating a "decline in masticatory function". Logistic regression analysis revealed that participants with an IGF-1 level ≤108 ng/mL had an odds ratio of 4.31 (p < 0.05) for a "decline in masticatory function". No significant association was found between the OC level and oral dysfunction.

CONCLUSIONS

These results suggest a possible relationship between lower serum IGF-1 levels and a decline in masticatory dysfunction in community-dwelling older people.

Relationship between Psychological Stress Determined by Voice Analysis and Periodontal Status: A Cohort Study

In modern society, evaluation and management of psychological stress may be important for the prevention of periodontal disease. The purpose of this study was to examine the relationship between psychological stress (vitality and mental activity) evaluated by Mind Monitoring System (MIMOSYS) and periodontal status. Forty students of Okayama University underwent the oral examination and self-reported questionnaire on the first day (baseline) and the 14th day (follow-up). Voice recording was performed every day with the MIMOSYS app during the whole study period. The participants completed the Patient Health Questionnaire (PHQ)-9 and Beck Depression Inventory (BDI) at baseline and at follow-up. Spearman’s rank correlation coefficient was used to determine the significance of correlations among variables. The PHQ-9 and BDI scores were negatively correlated with vitality in the morning. Change in vitality in the morning was significantly correlated with changes in periodontal inflammation. Mental activity was significantly correlated with change in mean probing pocket depth. This result shows that measurement of psychological stress using a voice-based tool to assess mental health may contribute to the early detection of periodontal disease.

Behavioral Patterns of Depression Patients and Control Population

Behavioral and multifactorial factors, such as psychological, nutritional, dental pathology, and physical activity habits, are factors that control depression. The objective of the present study was to analyze the differences in the behavioral, psychological, nutritional, dental pathology, and physical activity patterns of the depressed and control population. Forty-eight participants with depression (45.7 ± 12.0) and one hundred participants in a control group without any pathology or medication (48.9 ± 7.9) were interviewed using an online questionnaire. The multifactorial items of psychology, oral behavior, nutritional habits, and physical activity profile were analyzed through a set of questionnaires. The results showed how the depression group showed significantly higher psychological measures related to personality, anxiety, depression, loneliness, perceived stress, and psychological inflexibility than the control group. The control group showed significantly higher weekly vitality, vitality at the end of the week, weekly frequency of juice, wine, coffee, fresh vegetable salad, and Bristol scale than the depression group. Higher values of migraine headache, weekly soft drink frequency, and digestion after meals were found in the depression group. In addition, patients with depression also presented poor dental health, presenting higher rates of gastritis or heartburn, dry mouth, dental sensitivity, and sick days per year than the control group. Both groups presented a pattern of low physical activity. This information allows a better understanding of a multifactorial disease, as well as the creation of intervention and prevention protocols for this disease at a behavioral and lifestyle level.

The “Sling” Technique for Horizontal Guided Bone Regeneration: A Retrospective Case Series

The aim of this retrospective case series was to present a new technique, called the “sling technique”, for massive horizontal alveolar ridge augmentation through the innovative use of an expanded polytetrafluoroethylene (e-PTFE) membrane to reduce the risk of biological complications related to membrane exposure. Materials and Methods: Eligible patients for implant rehabilitation with a horizontal bone defect were enrolled in our study. All patients were treated with our new GBR approach, called the “sling technique” (ST), which consisted of covering the vestibular side of the bone defect with a stretched e-PTFE membrane. This technique allowed the amplification of the membrane surface as long as the compression and the immobilization of the underlying graft material remained (1:1 autologous bone and bovine xenograft). The membrane was placed far from the surgical incision of the mucosa to avoid infective complications. Pre- and post-regenerative surgery CBCT scans were used to assess the tissue gain amount after the GBR. Results: A total of 10 patients (4 females, 6 males; age range: 45–60 years old) were enrolled in our study and 33 implants were placed in regenerated bone. An average of 4 mm bone gain was achieved using the ST. No membrane exposures or biological complications were registered during the post-operative healing period. After a 24-month follow-up, a 100% implant survival rate was observed without hard or soft tissue dehiscence. Conclusion: The e-PTFE membrane positioned with the “sling technique” gave satisfactory results in horizontal bone augmentation. Considering the small sample, further confirmations with larger studies are needed.

Physical Frailty and Oral Frailty Associated with Late-Life Depression in Community-Dwelling Older Adults

Late-life depression is a major mental health problem and constitutes a heavy public health burden. Frailty, an aging-related syndrome, is reciprocally related to depressive symptoms. This study investigated the associations of physical frailty and oral frailty with depression in older adults. This large-scale cross-sectional study included 1100 community-dwelling older adults in Taiwan. The participants completed a dental examination and questionnaires answered during personal interviews. The 15-item Geriatric Depression Scale was used to assess depression, and information on physical conditions and oral conditions was collected. Multivariable logistical regression analysis was conducted to examine associations of interest. Significant factors associated with depression were pre-physical frailty (adjusted odds ratio (aOR) = 3.61), physical frailty (aOR = 53.74), sarcopenia (aOR = 4.25), insomnia (aOR = 2.56), pre-oral frailty (aOR = 2.56), oral frailty (aOR = 4.89), dysphagia (aOR = 2.85), and xerostomia (aOR = 1.10). Depression exerted a combined effect on physical frailty and oral frailty (aOR = 36.81). Physical frailty and oral frailty were significantly associated with late-life depression in community-dwelling older adults in a dose–response manner. Developing physical and oral function interventions to prevent depression among older adults is essential.

Factors Associated with Tooth Loss in General Population of Bialystok, Poland

Background: The aim of this study was to assess risk factors for tooth loss in the population of the city of Bialystok, in north-eastern Poland, taking into account the entire population and different age groups. The study included 1138 subjects divided into three subgroups: 20–44 years, 45–64 years, and 65–79 years. Participants were classified according to the number of teeth lost (0–8 vs. 9–28). Socio-economic variables, smoking history, and dental habits were collected through a questionnaire. Medical examinations provided data on the body mass index and the fasting blood glucose level. Data were statistically analysed using Mann-Whitney U, Student’s t, chi² tests, and binary logistic regression, p < 0.05. Results: For the general population, being female (OR 1.38, 1.07–1.79, p = 0.015), having secondary education (OR 4.18, Cl 2.97–5.87, p < 0.000), higher body mass index (OR 1.13, Cl 1.10–1.17, p < 0.000), higher fasting blood glucose level (OR 1.03 1.03–1.04, p < 0.000), being former smoker (OR 1.72, Cl 1.29–2.31, p < 0.000), ever smoker (OR 1.69, Cl 1.29–2.20, p < 0.000), current smoker (OR 1.62, Cl 1.15–2.29, p < 0.006), longer smoking period (OR 1.11, Cl 1.09–1.14, p < 0.000), last visit to the dentist over a year ago (OR 1.92, Cl 0.44–2.58, p < 0.000) and tooth brushing less than two times a day (OR 1.6, Cl 1.14–2.23, p < 0.006) were associated with losing more than 8 teeth. In the subgroup aged 20–44 years, only smoking duration was a risk factor for tooth loss (p = 0.02). For the middle-aged and oldest groups, education level (respectively p < 0.001, and p = 0.001), body mass index (respectively, p < 0.001, and p = 0.037), smoking status ever/former/current (respectively p < 0.001 and p = 0.002), smoking status never/ever (respectively p < 0.001 and p = 0.009), smoking duration (p < 0.001) were related to tooth loss. Additionally, in the elderly group, fasting blood glucose level (p = 0.044) and frequency of dental visits (p = 0.007) were related to tooth loss. We concluded that in the evaluated population, tooth loss was associated with socio-demographic, medical, and behavioural factors.

Association between self-reported oral disease/conditions and symptoms of depression among Iraqi individuals

AIMS

The negative impact of oral diseases on the function, economy, and general health of the population is well-documented. In the last decades, evidence linking increased expression of depression and oral diseases/conditions has significantly increased. The aim of this study is to assess the association between oral disease/conditions and self-reported symptoms of depression individuals.

METHODS

A specially designed questionnaire was distributed via social media for 1 week. It consisted of two main sections; the first section was dedicated to collect demographic variables and self-reported symptoms of oral diseases. The second section, Patient Health Questionnaire-9 (PHQ-9), was used to assess the severity of depression via nine questions using a 4-point Likert scale. Association between depression and oral disease was determined by linear regression analysis.

RESULTS

A total of 1975 participants responded fully to the questionnaire and were included in the final analysis. The majority of participants, about 60%, showed mild to moderate symptoms of depression, while 8.9% expressed severe symptoms. Oral diseases positively associated with depression were caries, missing teeth, gingival bleeding, gingival recession, teeth mobility, and dry mouth (R2 = .155). In contrast, increased esthetic level of teeth/gingiva significantly decreased the feeling of depression.

CONCLUSIONS

Results indicated that oral diseases, particularly those adversely affecting function and esthetics, were associated with symptoms of depression in Iraqi individuals. These findings highlighted the importance of maintaining oral health as part of the general psychological wellbeing of the population.

A Systematic Review on Caries Status of Older Adults

The aim of this systematic review was to provide an update on caries prevalence in older adults aged 60 years or above around the globe. Two independent reviewers performed a systematic literature search of English publications from January 2016 to December 2020 using Pubmed, Scopus, Embase/Ovid and Web of Science. The MeSH terms used were “dental caries”, “root caries”, “DMF index”, “aged” and “aged 80 and over”. Further searches in Google Scholar retrieved eight additional publications. The epidemiological surveys reporting the prevalence of dental caries or root caries or caries experience using DMFT (decayed, missing and filled teeth) and DFR (decayed and filled root) in older adults aged 60 years or above were included. Quality of the publications was assessed using the JBI Critical Appraisal Checklist for Studies Reporting Prevalence Data. Among the 5271 identified publications, 39 articles of moderate or good quality were included. Twenty studies were conducted in Asia (China, India, Vietnam, Singapore and Turkey), ten in Europe (Ireland, Norway, Finland, Germany, Portugal, Poland, Romania and Kosovo), three in North America (USA and Mexico), one in South America (Brazil), two in Oceania (Australia) and three in Africa (Malawi, Egypt and South Africa). The prevalence of dental caries ranged from 25% (Australia) to 99% (South Africa), while the prevalence of root caries ranged from 8% (Finland) to 74% (Brazil) in community dwellers. The situation was even worse in institutionalised older adults of which the mean DMFT score varied from 6.9 (Malawi) to 29.7 (South Africa). Based on the included studies published in the last 5 years, caries is still prevalent in older adults worldwide and their prevalence varies across countries.

Oral health-related quality of life is associated with the prevalence and development of depressive symptoms in older Japanese individuals: The Ohasama Study

OBJECTIVE

This prospective study investigated the cross-sectional association between impaired oral health-related quality of life (OHRQoL) and the prevalence of depressive symptoms, and the longitudinal association between impaired OHRQoL and development of depressive symptoms among older adults.

BACKGROUND

Previous studies have shown a relationship between poor oral health and depression among older adults; however, findings are inconsistent.

MATERIALS AND METHODS

Participants were 669 community-dwelling older Japanese individuals aged≥55 years (mean: 67.8 ± 7.2 years). Data of 296 participants were used for longitudinal analyses. OHRQoL was evaluated using the Oral Impacts on Daily Performances scale. Impaired OHRQoL was defined as the presence of at least one impact on the scale. Depressive symptoms were assessed using the Japanese version of the Zung self-rating depression scale with a cut-off score of 40.

RESULTS

The cross-sectional logistic regression model demonstrated that impaired OHRQoL was significantly associated with depressive symptoms (odds ratio [OR], 5.17; 95% confidence interval [CI], 2.99-8.95) independent of age, sex, body mass index, hypertension, cerebrovascular/cardiovascular disease, smoking, drinking alcohol, education, cognitive function, objective oral health (dentition status) and oral health behaviour (dental visit within 1 year). Similarly, impaired OHRQoL predicted the development of depressive symptoms within 4 years in a fully adjusted longitudinal model (OR, 6.00; 95% CI, 1.38-26.09).

CONCLUSION

Impaired OHRQoL was identified as a potential comorbidity of depressive symptoms and a predictor for depressive disorder later in life. OHRQoL may be a useful clinical outcome for elder patients with regard to their mental and oral health.

Prevalence and risk factors of anxiety and depression among the community-dwelling elderly in Nay Pyi Taw Union Territory, Myanmar

Providing elderly mental healthcare in Myanmar is challenging due to the growing elderly population and limited health resources. To understand common mental health problems among Myanmar elderly, this study explored the prevalence and risk factors of anxiety and depression among the elderly in the Nay Pyi Taw Union Territory, Myanmar. A cross-sectional study was conducted among 655 elderly by face-to-face interviews with a pretested questionnaire. Descriptive analysis and multiple logistic regression analyses were performed. The prevalence of anxiety and depression were 39.4% (33.5% for males and 42.4% for females) and 35.6% (33.0% for males and 36.9% for females), respectively. The adjusted odds ratio of having anxiety was significant for having low education level, having comorbidity, having BMI < 21.3, poor dental health, no social participation, and having no one to consult regarding personal problems, while that of having depression was significant for having comorbidity, having BMI < 21.3, poor vision, and having no one to consult regarding personal problems. The reported prevalence of anxiety and depression indicate the demand for mental healthcare services among Myanmar elderly. Myanmar needs to improve its elderly care, mental healthcare, and social security system to reflect the actual needs of its increasing elderly population. Screening for anxiety and depression among elderly with comorbidities should be promoted. Raising community awareness of mental health, encouraging social participation, and supportive counselling are also essential in combating anxiety and depression among Myanmar elderly.

Oral health practices and oral hygiene status as indicators of suicidal ideation among adolescents in Southwest Nigeria

Background

Oral health is a less-recognized correlate of overall and mental wellbeing. This study aimed to assess the relationship between suicidal behavior (ideation and attempt) and oral health practices and status, and to determine the effect of sex on these associations among Nigerian adolescents.

Methods

Household survey data were collected from 10 to 19-year-old adolescents in southwestern Nigeria. Dependent variables were daily tooth brushing, daily consumption of refined carbohydrates between meals, and oral hygiene status (measured by plaque index). The independent variable was lifetime suicidal ideation/attempt, dichotomized into ‘yes’ and ‘never’. ‘Daily tooth brushing’ and ‘daily consumption of refined carbohydrates between meals’ were included in two separate logistic regression models, and ‘oral hygiene status’ was included in a linear regression model. The models were adjusted for sex, age, and socioeconomic status. The linear regression model was also adjusted for frequency of daily tooth-brushing and of consumption of refined carbohydrates between meals. Interactions between sex and suicidal ideation/suicide attempt in association with dependent variables were assessed. Significance was set at 5%.

Results

We recruited 1,472 participants with mean age (standard deviation) of 14.6 (2.6) years. The mean plaque index was 0.84 (0.56), and 66 (4.5%) adolescents reported ever having suicidal ideation/attempt. Suicidal ideation/attempt was associated with significantly lower likelihood of tooth brushing (OR = 0.48, 95% CI: 0.26, 0.91), higher likelihood of consuming refined carbohydrates between meals (OR = 2.30, 95% CI: 1.29, 4.10), and having poor oral hygiene (B = 0.18, 95% CI: 0.05, 0.32). Among males, suicidal ideation/attempt was associated with less likelihood of eating refined carbohydrates between meals (OR = 0.96, 95% CI: 0.35, 2.61). Conversely, it was associated with a significantly higher likelihood of this outcome (OR = 4.85, 95% CI: 2.23, 10.55) among females.

Conclusion

The study findings suggest that poor tooth brushing habits and poor oral hygiene are indicators for risk of suicidal behavior for adolescents in Nigeria, while high sugar consumption may be an additional risk factor for adolescent females. These findings support the role of dental practitioners as members of healthcare teams responsible for screening, identifying and referring patients at risk for suicidal ideation/attempt.

Efficacy of denture adhesives in complete denture wearers compared to denture wearers not using denture adhesives. A systematic review

AIM

The objective of this systematic review was to evaluate the efficacy of denture adhesives (DAs) in completely edentulous denture wearers compared to not using DAs.

METHODS AND RESULTS

PubMed, Web of Science, Cochrane Library, and EMBASE were searched from the database inception up to 6 February 2020 for Randomized Controlled Trials (RCTs) involving patients with complete dentures in both arches where the use of DAs was compared to no use of DAs. A total of 497 abstracts were reviewed, resulting in inclusion of 10 RCTs. Outcomes reported in the included trials were thoroughly reviewed and tabulated. The Cochrane risk of bias tool was used. All 10 studies were assessed at unclear (10%) or high risk of bias (90%). Studies showed DAs improved mainly retention/stability, and masticatory/chewing ability/performance, compared to no adhesives.

CONCLUSION

Most studies showed favorable results for DAs on retention and stability of complete dentures, masticatory performance, patient's comfort and satisfaction. Due to the heterogeneity of the outcomes, unclear/high risk of bias and small sample sizes, the quality of the evidence was very low. More high-quality research is needed with improved blinding and use of standardized methods to evaluate the efficacy of DAs.

Depression, periodontitis, caries and missing teeth in the USA, NHANES 2009-2014

Purpose

This study aimed to investigate the association between self-reported depressive symptoms and oral diseases in US adults, including periodontitis, caries, missing teeth and untreated dental caries.

Design

This study was designed as a secondary data analysis of a cross-sectional survey. We conducted descriptive, multivariable logistic and Poisson regression analyses on weighted data.

Setting

US National Health and Nutrition Examination Survey 2009–2014 data.

Participants

Individuals aged ≥30 years who completed a periodontal examination and depression screening (n=9799).

Results

21.6% (28.9 million) of adults aged ≥30 years reported depressive symptoms, with a higher prevalence among females, current smokers and participants with lower income and education status. More than half of the adults with moderate depressive symptoms had periodontal diseases, and more than one-third had teeth with untreated dental caries. After adjusting for sociodemographics, behavioural factors, having diabetes and psychotherapeutic medication use, depressive symptoms were associated with poorer oral health. Severe depressive symptoms were associated with higher odds of mild periodontitis (2.20; 99% CI 1.03 to 4.66). For those with mild depressive symptoms, the mean number of missing teeth was 1.20 (99% CI 1.06 to 1.37) times the average of non-symptomatic individuals; and 1.38 times (99% CI 1.15 to 1.66) among individuals with moderate depressive symptoms.

Conclusions

Depressive symptoms were associated with mild periodontitis and a greater number of missing teeth, while having teeth with untreated dental caries was attributed to sociodemographic factors. Awareness of oral health status among patients with depressive symptoms can inform both dental and mental health providers to develop tailored treatment and help patients achieve overall wellness.

Barriers Affecting the Oral Health of People Diagnosed with Depression: A Systematic Review

Introduction

The problems of oral health of people diagnosed with depression are not adequately recognized, either in developed or developing countries. Social stigma, lack of self-interest, or even inadequate approaches of dental doctors towards the unique situation of this group of people this lead to excessive oral health problems.

Methods

The bibliographic database PubMed/Medline, Google Scholar, and Whiley online library were searched using the following text and MeSH as separate key terms and in combination: depression and oral health/dental caries/periodontal disease/tooth loss/utilization of oral health services/and barriers. The content of documents was analysed using qualitative methodology.

Results

Twenty-six original studies were included in the review. Level/severity of depression, medication and medical comorbidity are the most important medical barriers influencing the oral health of people diagnosed with depression. Dental fear and anxiety are mostly combined with low oral hygiene and bad oral health. Socioeconomic status, dental insurance, bad habits and education also have important roles in the oral health status of people diagnosed with depression.

Conclusion

Including individuals with depression and oral health problems in national health programs, creating specific prevention programs, or subsidizing the cost of treatment are some of the recommendations suggested as solutions.

Access to Dental Care and Depressive Illness: Results from the Korea National Health Nutrition Examination Survey

Background and Objectives: Recent evidence suggests that oral health is associated with various systemic diseases including psychiatric illnesses. This study examined the association between depression and access to dental care in Korean adults. Materials and Methods: A cross-sectional evaluation was performed using data from the Sixth Korea National Health and Nutrition Examination Survey 2014. The general characteristics of the participants, the current depression status, and issues with access to dental care were collected to evaluate the factors for not being able to make dental visits according to care needs. Results: The study population comprised a total of 5976 participants who were 19 years of age and older and represented 40.7 million Koreans. A multivariable logistic regression analysis with weighted observations revealed that participants with current depressive illness were about two times more likely to express that they could not make dental visits in spite of their perceived care needs (adjusted odds ratio (OR) = 2.097; 95% confidence interval (CI) 1.046–4.203). The reasons for not making dental visits included financial problems, perceived importance of the dental problem, and fear of visiting dental professionals. Conclusions: Korean adults with current depressive illness were less likely to make dental visits when they had dental care needs. To improve dental health accessibility for patients with depressive illness, coordinated efforts can be considered involving multidisciplinary health care professionals.

Association of Dental Caries, Retained Roots, and Missing Teeth with Physical Status, Diabetes Mellitus and Hypertension in Women of the Reproductive Age

OBJECTIVES

To investigate in women of reproductive age a possible association between particular dental diseases-dental caries, retained roots, and missing teeth-with some systemic conditions-physical status score- ASA (American Society for Anesthesiologists), diabetes mellitus, and hypertension.

METHODS

Dental and medical history were retrieved from the electronic files of dental patients. Statistical analysis was performed using cross tabulation with the Chi-square test to explore the significance of an association between variables pertaining to dental diseases and the investigated systemic conditions. Logistic regression was further used to explore the significance of the above dental diseases as predictors for systemic conditions.

RESULTS

A total of 1768 female patients in the age range 18-55 were included, with a mean age of 31.2 ± 10.13 years. A total of 228 (12.9%) patients had a chronic systemic disease within the ASA II category, 66 (3.7%) were diabetic, and 76 (4.3%) were hypertensive. Missing teeth were significantly associated with the ASA II category, diabetes mellitus, and hypertension (p < 0.001, p = 0.009, p = 0.005 respectively), while retained roots were significantly associated with the ASA II category only (p = 0.023). Logistic regression showed a low predictive capacity of models describing the three systemic conditions.

CONCLUSIONS

Diabetes mellitus and hypertension were the most common systemic diseases among the study sample. While carious teeth had no significant association with the investigated systemic conditions, retained roots were significantly associated with the ASA II category only, and missing teeth were significantly associated with all investigated systemic conditions. However, oral diseases expressed a low predictive power of these systemic conditions.
