Dental Loss in the Lower Socioeconomic Stratum of a Sample of the Chilean Population Born in the 19TH and 20TH Centuries / Pérdida Dental en el Estrato Socioeconómico Bajo de una Muestra de la Población Chilena Nacida en los Siglos XIX y XX

SUMMARY: Partial or total dental loss (edentulism) is associated with decreased quality of life. Chile has large socioeconomic gaps, which are also recognized in oral health, but it is not known how Edentulism has evolved throughout the country. The aim of this study was to determine the edentulism in people born during the 19th and 20th centuries in Chile, who died in the 20th century, and to compare it with current data from the Chilean Ministry of Health (MINSAL) to observe its evolution in the country. For this purpose, 60 3D models of skulls from the Subactual Osteological Collection of Santiago were analyzed (30 individuals per sex), in which the presence and absence of teeth in antemortem in the maxilla were analyzed. A high percentage of tooth loss was observed, with 65 % partial edentulism, a 30 % total edentulism, and only 5 % had complete dentition in this osteological collection. In addition, a significant decrease over time was found; in 2017, the percentage of complete dentition at the national level was 32.8 %. A higher frequency of edentulism was also found in females from the osteological collection, with a significant probability of twice as much edentulism as in males. However, this sex difference was smaller than those found in the current study. Our study is the first to compare edentulism in Chile in two different time periods, since, in addition to studying it in the 19th and 20th century, it is carried out with data from the present day and in line with previous research, reveals the importance of socioeconomic and sex variables for dental loss.

La pérdida parcial o total de dientes (edentulismo) se asocia a una disminución de la calidad de vida. Chile tiene grandes brechas socioeconómicas, que también se reconocen en la salud oral, pero se desconoce cómo ha evolucionado el edentulismo en el país. El objetivo de este estudio fue determinar el edentulismo en personas nacidas durante los siglos XIX y XX en Chile y fallecidas en el siglo XX, y compararlo con datos actuales del Ministerio de Salud de Chile (MINSAL) para observar su evolución en el país. Para ello, se analizaron 60 modelos 3D de cráneos de la Colección Osteológica Subactual de Santiago (30 individuos por sexo), en los que se analizó la presencia y ausencia de dientes en dentición antemortem en el maxilar. Se observó un alto porcentaje de pérdida dentaria, con un 65 % de edentulismo parcial y un 30 % de edentulismo total, y sólo un 5 % presentaba dentición completa en esta colección osteológica. Además, se encontró una disminución significativa a lo largo del tiempo; en 2017, la dentición completa a nivel país fue del 32,8 %. También se encontró una mayor frecuencia de edentulismo en las mujeres de la colección osteológica, con una probabilidad significativa del doble de edentulismo que en los hombres. Sin embargo, esta diferencia de sexo fue menor que la hallada en datos actuales. Este estudio es el primero que compara el edentulismo en Chile en dos épocas diferentes, ya que además de estudiarlo en los siglos XIX y XX, se realizó con datos de la actualidad y, en línea con investigaciones previas, revela la importancia de las variables socioeconómicas y de sexo en la pérdida dental.

Distribution of Edentulism by the Macro Determinants of Health in 204 Countries and Territories: An Analysis of the Global Burden of Disease Study.

OBJECTIVE: To carry out a comprehensive description of edentulism estimates by the macro determinants of health in 2000, 2010 and 2019 worldwide. METHODS: This ecological study analyzed data from the Global Burden of Disease Study (GBD) to describe the incidence rate, prevalence rate and years lived with disability (YLDs) rate due to edentulism by macro determinants of health (governance, macroeconomic policy, social policy, public policies, societal values), for 204 countries and territories. The estimates were reported as rates (cases/100,000 people), for people of both sexes aged 55 years or older. RESULTS: Countries belonging to the least privileged categories of the macro determinants showed the lowest prevalence rate, incidence rate, and YLD rate due to edentulism for all exposures. Countries with low government expenditure on health showed the lowest prevalence rate of edentulism in 2000 (18,972.1; 95 %CI 15,960.0 - 21,984.3) and 2010 (16,646.8; 95 %CI: 14,218.3-19,075.4) than those with high government expenditure on health in 2000 (25,196.6; 95 %CI: 23,226.9 - 27,166.2) and 2010 (21,014.7; 95 %CI: 19,317.9 - 22,711.5). Countries with low SDI showed the lowest YLDs in 2000 (321.0, 95 %CI: 260.1- 381.9), 2010 (332.0; 95 %CI: 267.7-396.3), and 2019 (331.6; 95 %CI: 266.6-396.5). CONCLUSION: The findings point to persistent inequalities in the distribution of edentulism between countries worldwide. The most privileged countries, with higher economic development, better governance, and better social and public policies, have shown higher rates of edentulism. CLINICAL SIGNIFICANCE: This model must be reconsidered by advancing toward upstream and midstream strategies, beyond its conventional downstream clinical interventions.

Long-term trends in the burden of edentulism in China over three decades: A Joinpoint regression and age-period-cohort analysis based on the global burden of disease study 2019.

Background: To investigate secular trends in edentulism incidence, prevalence, and years lived with disability (YLDs) rates in Chinese men and women from 1990 to 2019. Methods: Data were obtained from the Global Burden of Disease Study 2019. The annual percentage change and average annual percentage change were calculated using Joinpoint regression analysis. The age-period-cohort (APC) analysis estimated the independent age, period, and cohort effects. Results: From 1990 to 2019, the crude incidence, prevalence, and YLDs of edentulism in the Chinese population increased year by year, while the age-standardized incidence, prevalence, and YLDs decreased, and the latter was higher in women than in men. The APC analysis showed that the age effect increased in men and women from age 20 to 74 and decreased thereafter. The risk of tooth loss increased with age. However, the relationship was not linear. The temporal effect showed a gradual increase; the risk of missing teeth gradually increased with the changing modern living environment. The cohort effect showed a single decreasing trend, with the early birth cohort having a higher risk of tooth loss than the later birth cohort population. The age, period, and cohort effects were consistent for both sexes. Conclusion: Although the standardized incidence, prevalence, and YLD rate and cohort effect of dentition loss in China are declining, they are still causing a severe burden to China due to the continued aging of the population and the rising period effect. Despite the decreasing trends of the standardized incidence and prevalence of dentition loss and the rate of YLDs, China should develop more effective oral disease prevention and control strategies to reduce the increasing burden of edentulism in the older adult, especially in older women.

The Connection between Socioeconomic Inequalities and the Appearance of the Toothlessness in Mostar.

BACKGROUND: To determine the existence of the toothlessness within the patients in the area of Mostar. The aim is to determine the topography of toothlessness within the population of Mostar, according to Kennedy classification. The aim is to connect measures of socioeconomic status with the appearance of the toothlessness. To develop a model that includes a form of toothlessness and the socioeconomic status of the patients in Mostar. SUBJECTS AND METHODS: The study was conducted at the Health Center in Mostar and the Regional Medical Center in Mostar. The research was cross-sectional study. It included 800 patients who regularlyoccurred to the dental ambulance because of the toothlessness and because of the prosthodontics treatment. The measurement was conducted by the dentist based on the anonymous research cardboard at the first examination of the patient. The dentist will determine the topography of the toothlessness according to Kennedy classification and the etiology of the toothlessness. RESULTS: In the total sample of respondents, the toothlessness was significantly higher represented (P<0.001). The manifestation of thetoothlessness was significantly higher among temporary employees and the retirees (P<0.001). In the total sample, toothlessness affected the sociological status of a higher percentage of the respondents (P<0.001). CONCLUSION: In our study, in a total sample of respondents, toothlessness was significantly higher represented (90% of respondents). The influence on the sociological status of the patient is most visible in the groups with the lower material status.

Association of childhood socioeconomic status with edentulism among Chinese in mid-late adulthood.

BACKGROUND: The aim of this study was to examine the association between childhood socioeconomic status (SES) and edentulism. METHODS: The edentulous status of Chinese in mid-late adulthood was determined using self-reported lost all of teeth from the Health and Retirement Longitudinal Study (CHARLS). Childhood SES was determined based on the following parameters: the education, occupation and working status of the parents; financial situation of the family; relationship with the parents; care, love and affection from the mother; quarrels and fights between parents; primary residence; neighbors' willingness to help and with close-knit relationships. Adulthood SES was assessed by educational achievements. This study used principal component analysis (PCA) to select variables and binary logistic regression models to determine the association between childhood SES and edentulism. RESULTS: Data were available from a total of 17,713 respondents, 984 of whom were edentulous (2.9%). The prevalence of edentulism in mid- to late-age Chinese individuals was higher in those with poor childhood SES. In final regression model, edentulism was significantly associated with willingness of neighbors to help with close-knit relationships (OR = 0.89, 95% CI = 0.79-0.99), parents with high school education or above (OR = 1.18, 95% CI = 1.01-1.39) and drinking and smoking habits of the father (OR = 1.10, 95% CI = 0.97-1.24). CONCLUSION: Childhood SES was significantly associated with the prevalence of edentulism in mid- to late-age Chinese individuals. In particular, parents with high school education or above, unwillingness of neighbor to help with close-knit relationships, drinking and smoking habits of the father independent of adulthood SES were significantly associated with edentulism. Accordingly, the development of optimal recommendations and more effective intervention strategies requires considering the experiences in early life associated with poor SES contributes to poor oral health.

SES and correlated factors do not explain the association between periodontal disease, edentulism, and cancer risk.

PURPOSE: Severe periodontal disease and edentulism have been previously reported to be significantly associated with cancer risk and mortality, including in the Atherosclerosis Risk in Communities study (2018); however, complex sources of confounding by socioeconomic status (SES), and characteristics correlated with SES, could have been present in earlier analyses. METHODS: To capture life course SES and its correlates, we generated a propensity score and included it, along with other potential confounders such as smoking and obesity, into a Cox regression model to examine the association between periodontal disease and cancer risk. In addition, we stratified the model with the propensity score by low and high SES. All statistical tests were two-sided. RESULTS: Compared with our previous study, the associations for severe periodontitis and cancer incidence remained comparable after weighting by the propensity score (e.g., for total cancer: before weighting, hazard ratio = 1.24, 95% confidence interval = 1.07-1.42 vs. after weighting, hazard ratio = 1.23, 95% confidence interval = 1.05-1.44 when comparing severe periodontitis to no or mild periodontitis). Associations were comparable in low and high SES strata and statistically significant among participants with high SES. CONCLUSIONS: Complex sources of confounding by SES and its correlates are unlikely to fully account for the positive associations observed for periodontal disease and edentulism and cancer risk.

Dental Care Among Adults Aged 65 and Over, 2017.

Dental care is often an overlooked aspect of overall health care among older adults. Regular dental care is recommended for all older adults, even those with full dentures (1). Because Medicare does not cover routine dental care, older adults may have trouble accessing appropriate dental care (2). This report describes the prevalence, overall and by selected characteristics, of dental insurance, dental visits, and unmet need for dental care due to cost among adults aged 65 and over.

Indicators of oral health in older adults with and without the presence of multimorbidity: a cross-sectional study.

PURPOSE: The aim of this study was to determine whether there are differences in the distribution of various indicators of oral health among elderly people with and without multimorbidity (ie, two or more chronic diseases). SUBJECTS AND METHODS: A cross-sectional, comparative study was conducted using a sample of Mexican elderly individuals aged ≥60 years. The average age of the cohort was 79.06±9.78 years, and 69.1% were women. The variables indicating oral health were as follows: functional dentition, edentulism, hyposalivation, xerostomia, root caries and periodontitis. The multimorbidity variable was operationally categorized as follows: 0= subjects with no chronic disease or one chronic disease and 1= subjects with two or more chronic diseases. Questionnaires were used to collect information on various variables regarding general health. Likewise, the participants underwent a clinical oral examination. The analysis was performed using Stata 11.0. RESULTS: The overall prevalence of multimorbidity was 27.3%. The prevalences of various oral health indicators were as follows: without functional dentition 89.9%; hyposalivation 59.7%; edentulism 38.9% and self-reported xerostomia 25.2%. Dental caries were observed in 95.3% of the subjects, and the prevalence of severe periodontitis was 80%. We found a significant difference only in edentulism; its prevalence was higher among subjects with multimorbidity (55.3% vs 32.7%, P=0.015) than among those without multimorbidity. CONCLUSION: The presence of edentulism in this sample of Mexican older adults was higher in subjects with multimorbidity. Multimorbidity and oral diseases constitute a true challenge in elderly people, because they affect quality of life and are associated with high health care costs.

Associations of number of teeth with medical costs and hospitalization duration in an older Japanese population.

AIM: Many studies have reported close relationships between oral and systemic health. We explored the association of the number of remaining teeth with medical costs and hospitalization duration in people aged 75 and 80 years. METHODS: Oral health examinations were carried out at dental clinics in 2014. Medical cost and hospitalization duration data for fiscal year 2015 were obtained from the Mie Prefecture health insurer. We analyzed the data of 4700 individuals who met our inclusion criteria: 2745 75-year-olds and 1955 80-year-olds. The effects of remaining tooth numbers on medical costs and hospitalization days were analyzed using a generalized linear model with log link adjustment for confounders. RESULTS: Total medical costs for all diseases were significantly higher in those with 20-27, 10-19 and 1-9 teeth, and in edentulous older individuals, compared with those with 28 teeth. Outpatient medical costs for diabetes were significantly higher in those with 20-27 and 1-9 teeth. Inpatient medical costs for digestive cancers were significantly higher in those with 10-19 and 1-9 teeth, and in edentulous older individuals. Hospitalization for digestive cancer was significantly longer in those with 20-27, 10-19 and 1-9 teeth, and in edentulous older individuals, than in those with 28 teeth. The number of teeth as a continuous variable was significantly inversely associated with medical costs for cerebrovascular disease and digestive cancer, and hospitalization days for digestive cancer. CONCLUSION: Small numbers of teeth were associated with higher medical costs and longer hospital stays for older Japanese. Geriatr Gerontol Int 2019; 19: 335-341.

Oral health status of the disabled compared with that of the non-disabled in Korea: A propensity score matching analysis.

BACKGROUND: There are many types of disabilities, and each type has a variety related to socioeconomic factors. Such factors affect to many health problems of the disabled. However, surveys of the oral health status of the disabled in Korea are rare. OBJECTIVE: The purpose of this study was to estimate oral health disparity through comparing oral health status of the disabled to the non-disabled, adjusted for the net effect of the disability on oral health status. METHODS: A cross-sectional study was conducted among the disabled in urban and suburban areas in Korea from June to September 2016. People with physical, mental, and multiple disabilities took part in this survey. The clinical examinations were carried out by trained dentists. Statistical analysis was performed to quantify the association between oral health and socioeconomic status after restricting the analysis using a propensity score matching method. RESULTS: The disabled had more DMFT, DT, and MT, fewer FT, and fewer teeth than the non-disabled based on entire groups (P<0.01). No difference in the ratio of periodontitis was observed. The subjects with mental disabilities (MD) scored 3.09 (95% CI, 1.07-8.97), and those with multiple disabilities scored 4.37 (95% CI, 1.16-16.37) for edentulous status. The MD had an odds ratio of 1.34 (95% CI, 1.03-1.74), and those with multiple disabilities had an odds ratio of 1.75 (95% CI, 1.11-2.76) for the DMFT index. CONCLUSIONS: These results represent poor oral health status of the disabled compared to the non-disabled. Consequentially, we can verify that not only the existence of disability but also the type of disability has a decisive effect on oral health condition. This comparison is necessary to widen our approach to evaluate the actual status condition of the disabled.

Burden of oral diseases and noncommunicable diseases: An asia-pacific perspective.

BACKGROUND: At a population level, there are no systematic data to correlate the pattern of prevalence of noncommunicable diseases (NCD) with oral disease burden in South Asian countries. The influence of the age, gender, and geographical distribution on these diseases is not reported. We attempt to provide a population level correlation of occurrence using the Global Burden of Disease approach. MATERIALS AND METHODS: Using the data from the Global Burden of Diseases, 2016, the occurrence of oral diseases (dental caries of permanent teeth, edentulism (including severe tooth loss), and periodontal diseases) and various NCDs, based on geographical region, gender and age groups were collected and subjected to correlation statistics. Statistical Package for Social Services (Version 23) was used to analyze the results. P ≤ 0.05 was considered as statistically significant. RESULTS: Geographical location and age had a significant role in the occurrence of dental diseases. There was a considerable difference in rates of dental diseases and NCD prevalence in the various regions of Asia-Pacific. It was observed that for most of the NCDs, there was a linear significant relationship for edentulism as well as periodontal diseases with high statistical significance. DISCUSSION: The factors that contribute to the discrepancies, phenomenon, and relationship between the oral diseases and NCDs are discussed. The current state of the importance of oral health, in maintaining overall health is discussed. Methods by which policymakers could bring about a change by utilizing the principles of "Overton window" for mobilizing the support of people are presented.

Life course socioeconomic inequalities and oral health status in later life: ELSI-Brazil.

OBJECTIVE: To investigate the association between life course socioeconomic conditions and two oral health outcomes (edentulism and use of dental prostheses among individuals with severe tooth loss) among older Brazilian adults. METHODS: This was a cross-sectional study with data from the Brazilian Longitudinal Study of Aging (ELSI-Brazil) which includes information on persons aged 50 years or older residing in 70 municipalities across the five great Brazilian regions. Regression models using life history information were used to investigate the relation between childhood (parental education) and adulthood (own education and wealth) socioeconomic circumstances and edentulism and use of dental prostheses. Slope index of inequality and relative index of inequality for edentulism and use of dental prostheses assessed socioeconomic inequalities in both outcomes. RESULTS: Approximately 28.8% of the individuals were edentulous and among those with severe tooth loss 80% used dental prostheses. Significant absolute and relative inequalities were found for edentulism and use of dental prostheses. The magnitude of edentulism was higher among individuals with lower levels of socioeconomic position during childhood, irrespective of their current socioeconomic position. Absolute and relative inequalities related to the use of dental prostheses were not related to childhood socioeconomic position. CONCLUSIONS: These findings substantiate the association between life course socioeconomic circumstances and oral health in older adulthood, although use of dental prostheses was not related to childhood socioeconomic position. The study also highlights the long-lasting relation between childhood socioeconomic inequalities and oral health through the life course.

The burden of tooth loss in Italian elderly population living in nursing homes.

BACKGROUND: This survey aims to evaluate the prevalence and severity of tooth loss in the Italian elderly population living in nursing homes and to associate the oral data with demographic, socioeconomic factors, the Mini-Mental State Examination (MMSE), the Body Mass Index (BMI) and the Mini Nutritional Assessment (MNA) scores. METHODS: A cluster sample method was performed using each nursing home as a cluster. Twenty-three nursing homes located in the five areas of the Italy (North-West, North-East, Centre, South and Islands) were selected. An informed consent to participate was distributed by the personnel of the selected nursing homes and signed directly by subjects/caregivers; 2114 forms were distributed, 1998 forms signed and finally 1976 subjects were examined. Chewing ability was scored as good (≥10 functional units (FUs)), sufficient (7-10 FUs), and insufficient (< 7 FUs). The presence of prosthetic dental restorations was summarized as: absent of prosthesis, fixed prosthesis, removable prosthesis, combined prosthesis. Age, gender, socioeconomic status, MMSE, BMI and MNA were obtained from medical charts. RESULTS: Almost three quarters of the subjects were ≥ 80 years old (74.37%) and women (74.04%). The prevalence of edentulism was 42.10% with a large variation among the five areas of Italy (from 34.43% in Centre to 53.46% in North-West). Insufficient presence of FUs was preeminent in each age group (prevalence 42.10%) and statistically associated to age and to female gender (p <  0.01). Overweight/obese (7.47%) subjects showed the highest FUs. Area of living, MMSE (both < 0.01), BMI (p = 0.01) were statistically significant associated to the type of prosthetic dental restorations in the oldest group. Subjects with no mental impairment showed the highest percentage of prosthetic dental restorations (32.36%). CONCLUSIONS: More than half of the sample has an insufficient number of functional units for chewing and this is more pronounced in females. The presence and the type of prosthetic dental restorations are linked to cognitive impairment: the higher is the mental impairment the higher is the number of subjects with absence of prosthetic restorations. The findings of this national survey highlight the need for public health policy, aiming to increase awareness regarding oral health though health education.

Association between socioeconomic and health factors and edentulism in people aged 65 and older - a population-based survey.

AIMS: To study edentulism and use of dental services in a population-based sample of people aged 65 years and older from northern Sweden and western Finland. METHODS: In 2010, people aged 65, 70, 75 and 80 years who were living in one of 32 municipalities in northern Sweden and western Finland were invited to answer a questionnaire as part of the Gerontological Regional Database (GERDA) study ( n = 6099). The questionnaire contained items related to socioeconomic status, general health and edentulism. RESULTS: The prevalence of edentulism was 34.9% in Finland, compared with 20.6% in Sweden ( p < 0.001), 31.9% in rural areas, compared with 20.9% in urban areas ( p < 0.001), and 25% overall. The prevalence of edentulism rose from 17.8% in 65-year-olds, 23.8% in 70-year-olds, 33.5% in 75-year-olds and 37.3% in 80-year-olds ( p < 0.001), and was 23.8% in women, compared with 27% in men ( p < 0.001). In multivariate models, edentulism was associated with lower educational level (odds ratio (OR) 2.87, 95% confidence interval (CI) 2.31-3.58), low income level (OR 1.7, CI 1.09-1.47), residence in a rural area (OR 1.43, CI 1.23-1.66), male sex (OR 1.30, CI 1.12-1.52), dependence in instrumental activities of daily living (OR 1.48, CI 1.25-1.74), social isolation (OR 1.52, CI 1.17-1.98) and poor self-experienced health (OR 1.38, CI 1.17-1.62). CONCLUSIONS: One-quarter of the total sample was edentulous, with a higher prevalence of edentulism in Finland than in Sweden and in rural than in urban areas. Edentulism was associated with socioeconomic, psychological and health-related factors. These findings could be used to inform preventive measures and identify people aged 65 years and older who are in need of oral care.

Life course socioeconomic inequalities and oral health status in later life: ELSI-Brazil

ABSTRACT OBJECTIVE To investigate the association between life course socioeconomic conditions and two oral health outcomes (edentulism and use of dental prostheses among individuals with severe tooth loss) among older Brazilian adults. METHODS This was a cross-sectional study with data from the Brazilian Longitudinal Study of Aging (ELSI-Brazil) which includes information on persons aged 50 years or older residing in 70 municipalities across the five great Brazilian regions. Regression models using life history information were used to investigate the relation between childhood (parental education) and adulthood (own education and wealth) socioeconomic circumstances and edentulism and use of dental prostheses. Slope index of inequality and relative index of inequality for edentulism and use of dental prostheses assessed socioeconomic inequalities in both outcomes. RESULTS Approximately 28.8% of the individuals were edentulous and among those with severe tooth loss 80% used dental prostheses. Significant absolute and relative inequalities were found for edentulism and use of dental prostheses. The magnitude of edentulism was higher among individuals with lower levels of socioeconomic position during childhood, irrespective of their current socioeconomic position. Absolute and relative inequalities related to the use of dental prostheses were not related to childhood socioeconomic position. CONCLUSIONS These findings substantiate the association between life course socioeconomic circumstances and oral health in older adulthood, although use of dental prostheses was not related to childhood socioeconomic position. The study also highlights the long-lasting relation between childhood socioeconomic inequalities and oral health through the life course.

The social gradient in oral health: Is there a role for dental anxiety?

OBJECTIVE: To evaluate the contribution of dental anxiety to social gradients in different oral health outcomes and whether social gradients in oral health persist once dental anxiety is removed from the population examined. METHODS: Data from 9035 British adults were analysed. Participants' socioeconomic position (SEP) was measured through education and household income. Dental anxiety was measured with the Modified Dental Anxiety Scale. Poor subjective oral health, oral impacts on quality of life and edentulism among all adults and the number of teeth, the number of decayed, missing and filled surfaces (DMFS) and sextants with pocketing among dentate adults were the oral health outcomes. The contribution of dental anxiety to absolute and relative social inequalities in each oral health outcome (measured with the Slope and Relative Index of Inequality [SII and RII], respectively) was estimated from regression models without and with adjustment for dental anxiety and quantified with the percentage attenuation. Interactions between each SEP indicator and dental anxiety were used to test what would happen if dental anxiety were removed from the whole population. RESULTS: The largest contribution of dental anxiety to explaining oral health inequalities was found for education gradients in perceived outcomes (11%-13%), but dental anxiety explained <4% of social gradients in edentulism. Among dentate adults, dental anxiety accounted for <5% and <7% of education and income gradients, respectively. Only four of the 24 interactions tested were statistically significant. Hence, the education- and income-based SII and RII for oral impacts were nonsignificant among anxiety-free adults but were significant at higher levels of dental anxiety. CONCLUSIONS: Little support was found for the role of dental anxiety in explaining social inequalities in various perceived and clinical oral health measures. Oral health inequalities were found among both nondentally anxious and anxious participants.

Common risk factors and edentulism in adults, aged 50 years and over, in China, Ghana, India and South Africa: results from the WHO Study on global AGEing and adult health (SAGE).

BACKGROUND: Edentulism (loss of all teeth) is a final marker of disease burden for oral health common among older adults and poorer populations. Yet most evidence is from high-income countries. Oral health has many of the same social and behavioural risk factors as other non-communicable diseases (NCDs) which are increasing rapidly in low- and middle-income countries with ageing populations. The "common risk factor approach" (CRFA) for oral health addresses risk factors shared with NCDs within the broader social and economic environment. METHODS: The aim is to improve understanding of edentulism prevalence, and association between common risk factors and edentulism in adults aged 50 years and above using nationally representative samples from China (N = 11,692), Ghana (N = 4093), India (N = 6409) and South Africa (N = 2985). The data source is the World Health Organization (WHO) Study on global AGEing and adult health (SAGE) Wave 1 (2007-2010). Multivariable logistic regression describes association between edentulism and common risk factors reported in the literature. RESULTS: Prevalence of edentulism: in China 8.9 %, Ghana 2.9 %, India 15.3 %, and South Africa 8.7 %. Multivariable analysis: in China, rural residents were more likely to be edentulous (OR 1.36; 95 % CI 1.09-1.69) but less likely to be edentulous in Ghana (OR 0.53; 95 % CI 0.31-0.91) and South Africa (OR 0.52; 95 % CI 0.30-0.90). Respondents with university education (OR 0.31; 95 % CI 0.18-0.53) and in the highest wealth quintile (OR 0.68; 95 % CI 0.52-0.90) in China were less likely to be edentulous. In South Africa respondents with secondary education were more likely to be edentulous (OR 2.82; 95 % CI 1.52-5.21) as were those in the highest wealth quintile (OR 2.78; 95 % CI 1.16-6.70). Edentulism was associated with former smokers in China (OR 1.57; 95 % CI 1.10-2.25) non-drinkers in India (OR 1.65; 95 % CI 1.11-2.46), angina in Ghana (OR 2.86; 95 % CI 1.19-6.84) and hypertension in South Africa (OR 2.75; 95 % CI 1.72-4.38). Edentulism was less likely in respondents with adequate nutrition in China (OR 0.68; 95 % CI 0.53-0.87). Adjusting for all other factors, compared with China, respondents in India were 50 % more likely to be edentulous. CONCLUSIONS: Strengthening the CRFA should include addressing common determinants of health to reduce health inequalities and improve both oral and overall health.

Oral health needs of athletes with intellectual disability in Eastern Europe: Poland, Romania and Slovenia.

OBJECTIVES: The aims of this study were to evaluate the oral condition and treatment needs of Special Olympics (SO) athletes from Poland, Romania and Slovenia. METHODS: A cross-sectional study was performed with data collected through standardised oral screening of athletes who participated in the annual SO events held in Poland, Romania and Slovenia, between 2011 and 2012. The data were compiled and transferred to an SPSS data file for analysis using descriptive statistics. RESULTS: A total of 3,545 athletes participated in the study. Among the main findings, the prevalence of untreated decay was 41% in Poland and 61% in Slovenia, whilst 70% of the Romanian athletes had signs of gingival disease and only 3.8% presented molar fissure sealants. In addition, 47% of Polish athletes were in need of urgent treatment. CONCLUSIONS: Analysis of the results obtained following screening showed comparable oral health needs of athletes with intellectual disability among countries. Exploration of the oral health systems of the countries revealed similar significant co-payments and lack of incentive for dentists to treat patients with special needs. The results from Romania, Poland and Slovenia demonstrated the need for a structured system in which a special population is a target for oral-health-related education programmes and system-included preventive, restorative and maintenance interventions.

Burden of poor oral health in older age: findings from a population-based study of older British men.

OBJECTIVES: Evidence of the extent of poor oral health in the older UK adult population is limited. We describe the prevalence of oral health conditions, using objective clinical and subjective measures, in a population-based study of older men. DESIGN: Cross-sectional study. SETTING AND PARTICIPANTS: A representative sample of men aged 71-92 years in 2010-2012 from the British Regional Heart Study, initially recruited in 1978-1980 from general practices across Britain. Physical examination among 1660 men included the number of teeth, and periodontal disease in index teeth in each sextant (loss of attachment, periodontal pocket, gingival bleeding). Postal questionnaires (completed by 2147 men including all participants who were clinically examined) included self-rated oral health, oral impacts on daily life and current perception of dry mouth experience. RESULTS: Among 1660 men clinically examined, 338 (20%) were edentulous and a further 728 (43%) had <21 teeth. For periodontal disease, 233 (19%) had loss of attachment (>5.5 mm) affecting 1-20% of sites while 303 (24%) had >20% sites affected. The prevalence of gingival bleeding was 16%. Among 2147 men who returned postal questionnaires, 35% reported fair/poor oral health; 11% reported difficulty eating due to oral health problems. 31% reported 1-2 symptoms of dry mouth and 20% reported 3-5 symptoms of dry mouth. The prevalence of edentulism, loss of attachment, or fair/poor self-rated oral health was greater in those from manual social class. CONCLUSIONS: These findings highlight the high burden of poor oral health in older British men. This was reflected in both the objective clinical and subjective measures of oral health conditions. The determinants of these oral health problems in older populations merit further research to reduce the burden and consequences of poor oral health in older people.

Comorbid depression/anxiety and teeth removed: Behavioral Risk Factor Surveillance System 2010.

OBJECTIVE: The purpose of this study was to examine the association between participants (i) who reported having had clinical diagnoses of depression and anxiety with 6+ teeth removed and (ii) who reported having had clinical diagnoses of depression and anxiety with edentulism. METHODS: The Behavioral Risk Factor Surveillance System (BRFSS) Survey 2010 was used for the study. Analyses involved using SAS 9.3® to determine variable frequencies, Rao-Scott chi-square bivariate analyses, and Proc Surveylogistic for the logistic regressions on complex survey designs. Participants eligibility included being 18 years or older and having complete data on depression, anxiety, and number of teeth removed. RESULTS: There were 76 292 eligible participants; 13.4% reported an anxiety diagnosis, 16.7% reported a depression diagnosis, and 8.6% reported comorbid depression and anxiety. The adjusted logistic regression models were significant for anxiety and depression alone and in combination for 6+ teeth removed (AOR: anxiety 1.23; 95% CI: 1.10, 1.38; P = 0.0773; AOR: depression 1.23; 95% CI: 1.10, 1.37; P = 0.0275; P < 0.0001; and AOR: comorbid depression and anxiety 1.30; 95% CI: 1.14, 1.49; P = 0.0001). However, the adjusted models with edentulism as the outcome failed to reach significance. CONCLUSIONS: Comorbid depression and anxiety are associated independently with 6+ teeth removed compared with 0-5 teeth removed in a national study conducted in United States. Comorbid depression and anxiety were not shown to be associated with edentulism as compared with any teeth present.
