Int J Dent Hyg 2024; 22:521-529. [PMID: 37183553 DOI: 10.1111/idh.12680] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2022] [Revised: 02/06/2023] [Accepted: 04/02/2023] [Indexed: 05/16/2023]
Abstract
OBJECTIVE To validate the level of agreement between self-report and clinical examination for oral conditions and evaluate the effect of sociodemographic conditions on the validity of self-report among women aged 60 and older. METHODS A cross-sectional study was conducted in a social community center for seniors in Southern Brazil. Sociodemographic data (age, level of education, and income) were measured. Participants were interviewed and clinically examined for the number of teeth (DMF-T index) and the use of dental prostheses. The self-reported number of teeth in each arch and the use of dental prostheses were gathered through interviews. The level of agreement was estimated using the observed agreement, Kappa statistics, sensitivity/specificity (edentulism/prostheses) and Lin's concordance correlation coefficient, and related tests (number of teeth). The validity of the oral conditions was estimated according to sociodemographic information. RESULTS Ninety-nine women participated in the study. High levels of agreement were observed for edentulism (97.8%; 95%CI 92.8;99.7; Kappa 0.947) and the use of dental prostheses (97.0%; 95%CI 91.3;99.4; Kappa 0.922). In both conditions, despite achieving similar concordance correlation coefficients (ranging from weak to moderate), the mean number of upper teeth was lower in clinical examination (7.1 ± 5.2) compared with self-reported (8.6 ± 3.6), while the opposite was observed for lower teeth (clinical examination: 9.1 ± 3.4; self-reported: 6.6 ± 5.3). Larger differences were found among women of low income and educational levels. CONCLUSIONS Our findings suggest that the participants' socio-economic position might influence their self-reported number of teeth.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2024; 21:248. [PMID: 38541250 PMCID: PMC10970488 DOI: 10.3390/ijerph21030248] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 01/12/2024] [Revised: 02/11/2024] [Accepted: 02/15/2024] [Indexed: 07/23/2024]
Abstract
Oral health is an essential part of healthy aging and very little data exists around the disease burden for older adults in a long-term care setting. The aim of this scoping review was to estimate the disease burden of dental caries, periodontal disease, and tooth loss among older adults in Long-Term Care (LTC). This scoping review was conducted in accordance with the Joanna Briggs Institute methodology. A detailed strategy was used to conduct a comprehensive search of electronic databases: PubMed, Embase, and Dentistry and Oral Sciences Source (DOSS). The Rayyan AI platform was used to screen abstracts for assessment by one of five co-investigators. Results indicate that only one in three might have a functional dentition upon entry into LTC, and among those who are dentate, most might expect to develop at least one new coronal and one new root caries lesion each year. There is a need to better document the disease experiences of this group to tailor approaches to care that might reduce the avoidable suffering as a result of dental caries and periodontal disease.

Abstract
The proportion aged 60 years or older in the world's population is expected to double by 2050. In general, they have many complex diseases and poor oral health status. Oral health is one of the important health indicators of elderly people and it is affected by diverse factors, such as socioeconomic status. In this study, sexual difference was considered as an associated factor that is closely related to edentulism. The sexual difference might be more influential within the geriatric population because of lower economic and educational backgrounds at this stage. Edentulism was significantly higher among elderly females than males when combined with the education level. The lower the level of education, the higher the prevalence of edentulism as much as 24 ~ 28 times, especially in females (P = 0.002). These findings suggest a more complex relationship between oral health, socioeconomic status, and sexual difference.

Abstract
This study aimed to evaluate the pathways that explain the association between race/skin color and edentulism in elderly Brazilians. This was a cross-sectional study using data from participants aged 60 years or older from the 2019 Brazilian National Health Survey, a nationally representative population-based sample. Data were obtained by a structured interview and participants were classified as edentulous if they reported having lost all natural teeth. Information on race, socioeconomic level, behavioral aspects, psychosocial aspects, and access to dental care was collected by interviewers using a questionnaire. The pathways between race/skin color and edentulism were analyzed using structural equation modeling. The final sample of the study included 22,357 participants. Most participants were white (51.5%; 95% confidence interval [CI]: 50.3-52.6), and 36.8% (95%CI: 35.7-37.9) were edentulous. Race/skin color was indirectly associated with edentulism via enabling factors. These findings suggest that socioeconomic inequalities are key in explaining racial inequalities in edentulism among Brazilian older adults.

Abstract
AIM To assess the prevalence and associated factors with use of dental implants among older adults. METHODS This cross-sectional study was performed with home dwelling older adults from the cities Cruz Alta and Veranópolis, Brazil. The main outcome was obtained by a clinical oral examination, considering those with at least one dental implant. Independent variables were collected by a structured questionnaire. Crude and adjusted analysis was performed by Poisson regression with robust variance estimation; results are presented in prevalence ratio (PR) and 95% confidence interval. RESULTS It was included 569 participants. The overall prevalence of using at least one dental implant was 16.7%. Higher PR for the use of dental implants was observed in white individuals (PR:5.147; 95% CI:2.033-3.034), in those with at least medium income (PR:3.202; 95% CI:1.196-5.572) and in those with access to dental care in the last 12 months (RP:1.595; 95% CI:1.087-2.340). Older adults with a medium level of education (RP:0.484; 95% CI:0.240-0.978) and those that did not use dental floss (RP:0.627; 95% CI:0.240-0.978) demonstrated a significantly lower PR for use of dental implants. CONCLUSION A substantial prevalence of use of dental implants was observed among older adults. In addition, white ones, those with a better financial situation and users of dental floss presented higher use of dental implants.

Contextual and individual factors associated with self-reported tooth loss among adults and elderly residents in rural riverside areas: A cross-sectional household-based survey. PLoS One 2022; 17:e0277845. [PMID: 36413557 PMCID: PMC9681076 DOI: 10.1371/journal.pone.0277845] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2022] [Accepted: 11/03/2022] [Indexed: 11/24/2022] Open
Abstract
BACKGROUND Tooth loss is an oral health condition with high prevalence and negative impact on quality of life. It is the result of the history of oral diseases and their treatment as well as provision of dental care and access to dental services. Socioeconomic characteristics are determinants of tooth loss and living in rural areas is also a risk factor for its incidence. OBJECTIVE To identify contextual and individual factors associated with self-reported tooth loss among adults and elderly people living in rural riverside areas. METHODS A cross-sectional household-based survey was conducted in 2019 with rural riverside communities on the left bank of the Rio Negro River, Manaus, Amazonas. These communities are covered by a fluvial health team and two riverside health teams. Interviews were conducted in a representative random sample of dwellers aged ≥ 18 years, using electronic forms to obtain information on oral health conditions, demographic and socioeconomic characteristics, and use of and access to health services. The outcome was self-reported tooth loss. After the descriptive analysis of the data, a multilevel Poisson regression analysis was performed to estimate the prevalence ratio for the outcome. Variables with p-value ≤0.20 in the bivariate analyses were included in the multiple analysis considering the hierarchy between individual and contextual variables in the multilevel model. Variables with p-value ≤0.10 were kept in the final model and the significance level adopted was 0.05. RESULTS 603 individuals from 357 households were assessed (mean age 44.1 years). The average number of missing teeth was 11.2 (±11.6); 27.4% of individuals had lost more than 20 teeth (non-functional dentition) and 12.1% were completely edentulous. Contextual characteristic of primary healthcare offered was associated with the outcome. The tooth loss was lower in territories covered by riverside health teams. At individual level, tooth loss was greater in older individuals who had experienced dental pain over the past six months and whose sugar consumption was high. Black or brown individuals, individuals whose household income was higher, those who were on the Bolsa Família cash transfer program, those who consulted a dentist over the past year, and those who reported satisfaction with their teeth/oral health reported less tooth loss. CONCLUSION Tooth loss was associated with contextual territorial factors related to the healthcare service and individual demographic, behavioral, socioeconomic, and service-related characteristics as well as self-perceived oral health conditions. The findings suggest that actions focused on the oral health of these populations involve not only changes in the healthcare service organization, but also intersectoral policies that contribute to reducing social inequalities.

Abstract
The present study analyzed factors associated with the use of oral health services among elderly Brazilians. This was a cross-sectional study with data from the latest National Oral Health Survey (SB Brazil 2010), which considered a sample of 7,619 elderly individuals (65-74 years) for analysis. Structural Equation Modeling (SEM) was used, investigating the association between latent or observed variables, directly or mediated, in relation to the use of oral health services. Least squares estimators adjusted by mean and variance, were used by means of standardized coefficients, and standard error and confidence intervals, by applying the bootstrapping method with 1,500 iterations. Elderly individuals with a higher socioeconomic status, fewer missing teeth, and the presence of impacts of oral health conditions on their lives were directly associated with the outcome. Other factors associated with the mediated use of oral health services among elderly Brazilians included socioeconomic status, gender, age, and the use of prostheses, in addition to finding a correlation between prosthesis use and missing teeth. Tooth loss, along with other factors, played a prominent role in this study regarding the use of oral health services among elderly Brazilians, pointing to the need to expand access to dental prostheses in primary care.

Abstract
Abstract
Background
The aim of this study was to assess the income-related inequality of edentulism among the aged in China and identify the contributing factors.
Methods
A secondary analysis of data from the 4th National Oral Health Epidemiology Survey in China was conducted, and 65–74 years old were selected for the analysis of income-related inequality of edentulism. The concentration curve, Concentration index (CI) and Erreygers-corrected concentration index (EI) were used to represent inequality and its degree qualitatively and quantitatively, respectively. A decomposition method based on probit model was employed to determine the contributors of inequality, including demographic factors, income status, oral health-related knowledge, attitude and practices and self-perceived general health status.
Results
In China, aged people with edentulism were concentrated in the poor. The CI was − 0.2337 (95% CIs: − 0.3503, − 0.1170). The EI was − 0.0413 (95% CIs: − 0.0619, − 0.0207). The decomposition results showed that income (75.02%) and oral health-related knowledge, attitude and practices (15.52%) were the main contributors to the inequality.
Conclusion
This study showed that pro-poor inequality among the elderly with edentulism existed in China. Corresponding policies against the contributors could be considered to promote the health equality of the elders.

Abstract
OBJECTIVES There are limited longitudinal data regarding gingival inflammation in adults. This study aimed to assess changes in gingivitis over 4 years and to determine protective factors. METHODS A representative sample of 1023 adults living in Porto Alegre, Brazil, was obtained in the Caries-Perio Collaboration Study. At follow-up, 402 individuals were re-examined. Gingivitis was assessed by the gingival bleeding index (GB) at both time points. Individuals were dichotomized into those showing reductions ≥ 15% and those showing reductions < 15% or increase in bleeding sites. Multivariable Poisson regression models were fitted with 11 possible risk factors, estimating relative risks (RR) and 95% confidence intervals (95% CI). RESULTS Percentage of individuals with GB ≥ 10% reduced from 72.4% to 53.8%. Bleeding sites significantly reduced (25.9%-20.1%), and in a higher magnitude in buccal/palatal sites (34.1%-24.0%). 31.0% of individuals presented GB reduction ≥ 15% in all sites. Toothbrushing ≥ 3 times/d increased 72% the probability of ≥15% GB reduction compared with ≤1/d (RR = 1.72; 95% CI 1.01-3.16). For each 10 pack-years smoked, the probability of ≥15% GB reduction was 3% higher (RR = 1.03; 95% CI: 1.01-1.04). At buccal/palatal sites, normal weight individuals had 26% higher probability of reducing GB than overweight-obese individuals (RR = 1.26; 95% CI: 1.01-1.62). A 5% higher decrease in GB sites was observed in the absence than the presence of periodontitis. Younger individuals had higher reduction in GB sites. CONCLUSIONS In the studied population, gingivitis reduced over time, with younger age, better oral hygiene, absence of periodontitis and normal weight being found to be protective factors. Smoking was associated with lower levels of gingivitis over time, probably due to its vasoconstrictive effect.

Abstract
BACKGROUND Based on the 2018 classification, we aimed to determine the prevalence, distribution, and progression of periodontitis in the rural Chinese population without access to dental care. METHODS In all, 404 subjects (28.7 ± 8.9 years, M:F = 182:222) were randomly enrolled in 1992 and re-called in 1996. With the new classification, the prevalence and distribution of stage, grade, and extent were characterized. Stage progression was compared with the progression of clinical attachment loss (CAL) and radiographic bone loss (RBL). RESULTS At baseline, 94.1% villagers suffered from periodontitis, of whom 53.7% were in stage III/IV. The prevalence of stage III/IV increased from 18.2% in the age group of 15 to 24 years to 60.9% in 25 to 34-year-old group and 88.7% in the 35 to 44-year-old group. Significantly more stage III/IV, generalized, and grade C periodontitis were found in male villagers than female villagers. In 1996, the prevalence rate of periodontitis increased to 98.5%, with 80.0% in stage III/IV. Further, 84.2% villagers presented with grade C periodontitis based on longitudinal ΔCAL. The rate of progression (≥1 site with ΔCAL ≥3 mm) was 63.7%. Stage progression correlated significantly with CAL and RBL progression in stage I/II, but this association was not found in stage III/IV. Among subjects with disease progression in stage III/IV, 90.4% shifted from localized to generalized cases. Furthermore, ceiling effects were observed in stage III/IV. CONCLUSIONS In villagers without access to dental care, 94.1% suffered from periodontitis, with more than half having stage III/IV disease based on the 2018 classification. The majority cases presented with rapid periodontal progression. Although stage progression correlated significantly with CAL and RBL progression in stage I/II, ceiling effects existed in stage III/IV.

Association of childhood socioeconomic status with edentulism among Chinese in mid-late adulthood. BMC Oral Health 2019; 19:292. [PMID: 31884947 PMCID: PMC6935473 DOI: 10.1186/s12903-019-0968-1] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2019] [Accepted: 11/22/2019] [Indexed: 12/31/2022] Open
Abstract
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.

Abstract
Background: Updated information on oral health status could be used to monitor oral disease patterns, as widespread variations in oral health outcomes within and between different countries are reported. Aim: The objective was to examine the status of oral and systemic health and their association with demographic characteristics of the population attending a public dental center. Methods: A cross-sectional secondary analysis of the patients’ record was conducted during June 2017 attending the dental center of Madina Teaching hospital Faisalabad, Pakistan. Study variables were analyzed using the t test and the c2 test with a significance level of P ≤ .050. Results: The mean age of the study sample was 31.9 ± 14.5 years; 56% were females; 48% had primary or higher education; 9% were hypertensive; 5% had hepatitis; and 5% diabetes mellitus; 52% were with poor oral hygiene, 68% had dental caries, 84% had no fillings, 27% had tooth loss, and 99% functional dentition; 74% patients had calculus, 67% had gingivitis, and 5% had periodontitis. Age was the strongest risk indicator. Dental caries, tooth loss, poor oral hygiene, gingivitis, periodontitis, and tooth mobility were significantly associated with diabetes mellitus; tooth loss and tooth mobility were associated with cardiac disease; tooth loss, periodontitis, and tooth mobility were associated with hypertension, whereas tooth loss and calculus were associated with hepatitis. Higher age and lower income were positively associated with poor oral hygiene. Conclusion: Age and gender remain to be the strongest predictors for both oral and systemic conditions. Poor oral health and tooth loss showed a strong relationship with chronic systemic conditions.

Abstract
INTRODUCTION Despite the improvement in oral health conditions observed in the Brazilian population, there are still high social inequalities that must be monitored. OBJECTIVE To evaluate income inequality in oral hygiene practices, oral health status and the use of dental services in the adult and senior Brazilian population. METHODS Data from the National Health Survey conducted in 2013 (Pesquisa Nacional de Saúde - PNS 2013) were used for the population aged 18 years old or older. RESULTS Inequalities were found among the income strata in most of the oral health indicators evaluated. The greatest inequalities were observed in the use of dental floss, in hygiene practices (PR = 2.85 in adults and PR = 2.45 in seniors), and in total tooth loss (PR = 6.74 in adults and PR = 2.24 in seniors) and difficulty in chewing (PR = 4.49 in adults and PR = 2.67 in seniors) among oral condition indicators. The magnitude of inequalities was high in both groups in most oral condition indicators. Income was a factor that persisted in limiting access to dental services, and even the lower income segments had high percentages that paid for dental consultations. CONCLUSION Based on data from the first PNS, the findings of this study enabled the identification of oral health and dental care aspects more compromised by income differentials, thus, contributing to the planning of dental care in Brazil and to stimulate the monitoring of these disparities with data from future surveys.

The relationship between tooth loss and mortality from all causes, cardiovascular diseases, and coronary heart disease in the general population: systematic review and dose-response meta-analysis of prospective cohort studies. Biosci Rep 2019; 39:BSR20181773. [PMID: 30530864 PMCID: PMC6328868 DOI: 10.1042/bsr20181773] [Citation(s) in RCA: 46] [Impact Index Per Article: 9.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2018] [Revised: 11/12/2018] [Accepted: 11/26/2018] [Indexed: 12/20/2022] Open
Abstract
Background: The association of tooth loss with mortality from all causes, cardiovascular diseases (CVD), and coronary heart disease (CHD) has been studied for many years; however, the results are inconsistent. Method: PubMed, Embase, Web of Knowledge, and Cochrane Oral Health Group’s Trials Register databases were searched for papers published from 1966 to August 2018. We conducted dose–response meta-analysis to quantitatively evaluate the relation between tooth loss and risk of mortality from all causes, CVD, and CHD. Results: In the present study, 18 prospective studies conducted until August 2018 were considered eligible for analysis. In the analysis of linear association, the summarized relative risk (RR) values for each 10-, 20-, and 32-tooth loss for all-cause mortality were 1.15 (1.11–1.19), 1.33 (1.23–1.29), and 1.57 (1.39–1.51), respectively. Subgroup and sensitivity analyses showed consistent results. A linear relationship was found among all-cause mortality, with Pnonlinearity = 0.306. The susceptibility to all-cause mortality increased by almost 1.48 times at very high tooth loss (28–32), and slight flattening of the curve was noted. However, the summarized RR values for increment for 10-, 20-, and 32-tooth loss were not or were marginally related to increased risk of mortality from CVD/CHD. Subgroup and sensitivity analyses revealed inconsistent results. Tooth loss showed linear association with CHD mortality but not with CVD mortality. The susceptibility to all-cause mortality increased by almost 1.48 and 1.70 times for CVD and CHD, respectively, at very high tooth loss (28–32). The curve exhibited slight flattening; however, no statistical significance was detected. Conclusion: In the meta-analysis, our findings confirmed the positive relationship between tooth loss and susceptibility to all-cause mortality, but not for circulatory mortality. However, the finding that tooth loss might play a harmful role in the development of all-cause mortality remains inconclusive. Tooth loss may be a potential risk marker for all-cause mortality: however, their association must be further validated through large prospective studies.

Abstract
Abstract Introduction Cohabitation and social interaction programs have been shown to enhance several aspects of the quality of life of the elderly. Objective This observational study assessed the oral health and oral health perception of participants of an elderly cohabitation program in the state of Santa Catarina, Brazil. Material and method Calibrated dental students examined/interviewed 235 participants of the program. The oral examination considered Decayed, Missing, and Filled Teeth (DMFT) index, Community Periodontal Index (CPI), Periodontal Attachment Loss (PAL), use and need of prostheses, and presence of oral mucosal lesions. Oral health perception was verified with the Geriatric Oral Health Assessment Index (GOHAI) questionnaire. Data were analyzed with descriptive statistics and chi-square test (α=0.05). Result The mean DMFT index was 24.3 teeth, with emphasis on the ‘Missing’ category. Upper and lower prosthetic needs were 53.6 and 71.1%, respectively. Fifty-five per cent of participants presented oral mucosal lesions. Moderate oral health perception prevailed (43%), with mean GOHAI score of 29.9. The negative perception on physical and pain/discomfort dimensions was statistically associated with lower prosthetic need (p<0.05). Conclusion The participants of the cohabitation program presented poor oral health and prevalence of moderate oral health perception. Lower prosthetic need was associated with negative perception.

Abstract
BACKGROUND Little information exists about the loss of all one's teeth (edentulism) among older adults in Indonesia. The aim of this study was to investigate the prevalence of edentulism and associated factors among older adults in Indonesia. METHOD This study examines the self-reported prevalence of edentulism and associated factors among older adults (50 years and older) in a cross-sectional national study using the Indonesia Family Life Survey IFLS-5, 2014/15. The community-based study uses a multi-stage stratified sampling design to interview and assess household members, with a household response rate of over 90%. RESULTS The overall prevalence of edentulism was 7.2, 29.8% in 80 years and older and 11.8% in those with no formal education. In adjusted Poisson regression analysis, older age, living in five major island groups and having functional disability were associated with edentulism. In addition, among men, having quit and current tobacco use and among women, having low social capital were associated with edentulism. Further, in adjusted analysis, among men, edentulism was positively associated with hypertension and negatively associated with diabetes, and among women, edentulism was associated with functional disability. CONCLUSIONS Results suggest that overall and/or among men or women that older age, living in five major island groups, having functional disability, tobacco quitters and users and those with low social capital was associated with edentulism. The identified associated factors of edentulism may be utilized in oral health programmes targeting older adults in Indonesia.

Abstract
The aim of this study was to estimate self-reported prevalence of edentulism, severe tooth loss and lack of functional dentition in elders, and to identify potential associated factors. A population based cross-sectional study was carried out with 1,451 elders (≥60 years), in Pelotas, RS, Brazil. Crude and adjusted prevalence ratios were estimated using Poisson regressions. The prevalence of edentulism, severe tooth loss and lack of functional dentition was 39.3%, 60.9% and 82.7%, respectively. The factors positively associated with tooth loss in the three-degree severity were sex (females), older individuals, low familial income, low level of schooling and having the last dental visit longer than 24 months ago. The high prevalence of tooth loss in its different degrees of severity and the association with preventable factors highlight the need of programs focused on elders, emphasizing the prevention of tooth loss and need for prosthetic rehabilitation.

BMC Oral Health 2016; 17:29. [PMID: 27465011 PMCID: PMC4964081 DOI: 10.1186/s12903-016-0256-2] [Citation(s) in RCA: 28] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2016] [Accepted: 07/15/2016] [Indexed: 11/26/2022] Open
Abstract
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.

Abstract
This study conducted a systematic review to assess the bi-directional association between tooth loss/edentulism and obesity. Electronic searches were performed in four different databases. Observational studies that tested associations between tooth loss/edentulism and obesity as either exposures or outcomes were included. Additionally, meta-analyses, funnel plots and sensitivity analyses were conducted to synthesize the evidence. A total of 549 articles were identified in the electronic database search. Out of which, 16 studies were included within the meta-analyses: 75% considered tooth loss/edentulism as exposure and obesity as outcome, whereas 25% alternatively considered obesity as exposure and tooth loss/edentulism as outcome. Pooled estimates showed that obese individuals had 1.49 (95%CI 1.20-1.86) and 1.25 (95%CI 1.10-1.42) times higher odds of having any tooth loss and edentulism, respectively. Alternatively, when tooth loss or edentulism were considered as exposures, individuals with any tooth loss had 1.41 (95%CI 1.11-1.79) times higher odds for obesity, while edentates had even higher odds (OR 1.60; 95%CI 1.29-2.00). The results indicate a bi-directional association between tooth loss and obesity. Considering that all selected studies were of cross-sectional study design limiting inferences on temporality, longitudinal prospective studies are required to test the causal relationship between tooth loss/edentulism and obesity or vice a versa. © 2016 World Obesity.

Abstract
OBJECTIVES This study evaluated the prevalence and severity of tooth loss in Uruguayan elders, assessing its association with demographic, socioeconomic, and behavioral factors; the use of health services; and self-reported dental treatment need. METHODS A population-based cross-sectional study was done among Uruguayan individuals of ages 65-74 years. Data were collected through questionnaires and clinical examinations. The dependent variable, tooth loss, was classified into three distinct outcomes: functional dentition (≥20 teeth), severe tooth loss (<9 teeth), and edentulism. The independent variables were: sex, socioeconomic status, use of health services, hypertension, diabetes mellitus, tobacco use, frequent consumption of alcohol, hygiene habits, and need for dental care. RESULTS The sample comprised 341 individuals, and the mean number of teeth present was 9.73 (95% confidence interval, 8.77-10.69) for each individual. After multivariate analysis, lack of a functional dentition, severe tooth loss, and edentulism were found to be associated with lower socioeconomic level, frequent consumption of alcohol, and receiving treatment from the public health system (P < 0.05). Individuals with self-reported dental treatment need had more severe tooth loss and presented a higher degree of edentulism (P < 0.05). CONCLUSIONS There is a high and severe prevalence of tooth loss in elderly Uruguayans, especially among those from lower socioeconomic levels. Our findings highlight the importance of public health policies to prevent and treat tooth loss.

Abstract
AIM To assess whether the relationship between socioeconomic position (SEP) and periodontal health fitted the Critical Period or the Social Mobility life course models. METHODS A nationally representative sample of 5570 Korean adults from KNHANES IV study. Log-binomial regression models adjusting for adulthood or childhood socioeconomic (SES) variables was used to assess independent effects of socioeconomic differences for childhood, adulthood and period of transition from child to adult in periodontal health. RESULTS In the Critical Period model, poorer periodontal status was associated with SES disadvantage in adulthood and not predicted by SES disadvantage in childhood. For the intergenerational Social Mobility model, prevalence of current periodontal disease was only different for females aged 30-39 and 40-49 years, after adjustment. Prevalence of periodontal disease in females was highest in the downwardly mobile group. CONCLUSIONS The Critical Period model was better at explaining association between socioeconomic position and periodontal health, such as the adulthood socioeconomic variables (SEP), had a stronger effect than childhood factors on periodontal disease. The Social Mobility model explained more of the variation in the association between SEP and periodontal health among women than among men.

Abstract
This population-based cross-sectional study aimed to assess the prevalence and risk indicators for tooth loss due to dental caries among 12-year-old schoolchildren from South Brazil. 1,528 out of 1,837 (participation rate = 83.17%) schoolchildren were included. Tooth loss prevalence was 5.81% (95% CI = 3.71-8.98) and 0.08 (95% CI = 0.04-0.12) teeth were missing. Schoolchildren with low socioeconomic status (OR = 2.28, 95% CI = 1.23-4.21), who repeated years in school (OR = 1.56, 95% CI = 1.01-2.42), and with gingivitis (OR = 1.81, 95% CI = 1.33-2.45) were more likely to have missing teeth. Schoolchildren brushing 2 times/day (OR = 0.78, 95% CI = 0.64-0.96) or more (OR = 0.49, 95% CI = 0.33-0.74), and those with dental insurance or private dentists (OR = 0.60, 95% CI = 0.39-0.93) were less likely to present missing teeth. © 2014 S.

Abstract
OBJECTIVES The natural progression of periodontitis in the Chinese population is not well researched. We investigated the progression of periodontal disease over 4 years in 15-44-year-old Chinese villagers with no access to regular dental care. METHODS In 1992, 486 villagers were enrolled, and in 1996, 413 villagers were re-examined. Probing depth (PD) and clinical attachment level (CAL) were examined at six sites per tooth. Sites with ΔCAL ≥3 mm were defined as active sites. Cross-sectional and longitudinal analyses were performed using means and percentile plots. RESULTS The mean CAL increased by 0.26 mm over 4 years. The incidence of periodontitis (at least one site with CAL ≥3 mm) was 8%. The incidence of periodontitis among those with no periodontal disease at baseline was 44.9%. Seventy-eight percent of the subjects had at least one active site. In the 15-24-year group, 244 of 401 active sites had gingival recession, while only 51 active sites had both gingival recession and deeper pockets. In the 25-34-year and 35-44-year groups, almost one-third of the active sites (329/1087) and more than one-third of the active sites (580/1312) respectively had a combination of gingival recession and deeper pockets. CONCLUSIONS In this study, we demonstrated that in Chinese population without regular dental care, both the initiation of periodontitis and progression of previously existed periodontitis contributed to the natural progression of periodontitis and periodontal pocketing played a greater role with age increasing. CLINICAL SIGNIFICANCE This rare study reports the natural progression of periodontal disease in a group of Chinese villagers (15-44 years) with virtually no access to regular dental care.

Prevalence of loss of all teeth (edentulism) and associated factors in older adults in China, Ghana, India, Mexico, Russia and South Africa. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2014; 11:11308-24.

Abstract
Little information exists about the loss of all one’s teeth (edentulism) among older adults in low- and middle-income countries. This study examines the prevalence of edentulism and associated factors among older adults in a cross-sectional study across six such countries. Data from the World Health Organization (WHO’s) Study on global AGEing and adult health (SAGE) Wave 1 was used for this study with adults aged 50-plus from China (N = 13,367), Ghana (N = 4724), India (N = 7150), Mexico (N = 2315), Russian Federation (N = 3938) and South Africa (N = 3840). Multivariate regression was used to assess predictors of edentulism. The overall prevalence of edentulism was 11.7% in the six countries, with India, Mexico, and Russia has higher prevalence rates (16.3%–21.7%) than China, Ghana, and South Africa (3.0%–9.0%). In multivariate logistic analysis sociodemographic factors (older age, lower education), chronic conditions (arthritis, asthma), health risk behaviour (former daily tobacco use, inadequate fruits and vegetable consumption) and other health related variables (functional disability and low social cohesion) were associated with edentulism. The national estimates and identified factors associated with edentulism among older adults across the six countries helps to identify areas for further exploration and targets for intervention.

Abstract
Different reasons can contribute to classifying dental prosthesis wearers as high-risk individuals in relation to dental biofilm accumulation. These include a past history of oral disease, age and additional retentive areas. Other common complaints include inflammation and halitosis. Moreover, prosthesis replacement and prosthetic pillar loss are generally associated with caries and periodontal disease recurrence. Therefore, the present study undertook to make a critical review of the literature, aiming at discussing the main aspects related to chemical agent prescriptions for dental prosthesis wearers. Most of the articles were selected based on relevance, methods and availability in regard to the specific subject under investigation, without considering publication year limitations. Different types of prostheses and their impact on teeth and other oral tissues were reported. It was demonstrated that there is greater biofilm buildup and increased inflammatory levels in the presence of different types of prostheses, suggesting that additional measures are required both on population-wide and individual levels in order to control these factors. Mechanical control consists of a combination of manual or electric toothbrush and toothpaste, as well as specific devices for interdental cleaning. Although many chemical agents exhibit antimicrobial benefits when used for prosthesis disinfection, only a few agents can be used safely without causing damage. Regarding the selection of antiseptics by the overall population, chlorhexidine is the most indicated in the short term and in sporadic cases. The most indicated adjuncts to overcome the deficiencies and limitations of daily mechanical biofilm control are products containing essential oils as active ingredients.

Abstract
OBJECTIVES Polyamide-12 (PA) is a flexible material suited for denture bases and clasping. This study investigated its potential aging effects with a focus on surface roughness, color stability, and elasticity. METHODS PA specimens (Valplast) of 40×10×2 mm and equally measuring PMMA specimens (Palapress) as control were fabricated. Color changes after storage in air, water, coffee, and red wine (n=10) were measured using the CIE L*a*b* color specification. Elasticity after thermocycling (1000, 3000, and 7000 cycles, n=15) was measured by three-point bending testing. Mean surface roughness (Ra) was determined after storage in the liquids mentioned above and thermocycling (n=10). RESULTS Tukey's HSD test (P<0.05) revealed statistically significant color changes of PA in red wine (ΔE=4.27 after 12 days, ΔE=6.90 after 12 days) and coffee (ΔE=3.93 after 36 days) but no color changes in PMMA. Elastic modulus of PA was 845 MPa and not affected by thermocycling (Tukey's HSD test, P>0.81). Dry specimens showed significantly decreased elasticity (P<0.001). Mean surface roughness (PA 0.20 μ m, PMMA 0.28 μ m) did not change significantly after thermocycling or storage (Mann-Whitney U-test, 0.16<P<0.65). SIGNIFICANCE PA exhibited a higher susceptibility to discoloration than PMMA. Neither surface roughness nor elasticity of PA was altered by artificial aging.

Abstract
The experience and meaning of tooth loss and replacement has varied historically and culturally but has received relatively little attention from social scientists. Our study set out to understand these experiences in the context of the arrival of newer, dental implant treatments. Semi-structured qualitative interviews were carried out with 39 men and women who had experienced tooth loss and replacement. A thematic analysis was sensitised by previous sociological work on chronic illness, particularly Bury's notion of biographical disruption. We found that while for some individuals the loss of a tooth was relatively insignificant, for others it was devastating and disruptive. In seeking to understand this difference, the concept of biographical disruption was a helpful analytical tool. Our analysis identified two forms of disruption. The first related to the meanings of tooth loss (the neglected mouth) and denture wearing (a marker of old age). The second, embodied, disruption concerned the relationship between the self and mouth in those wearing dentures (the invaded, unreliable mouth) and could occur even where tooth loss and denture wearing had been biographically anticipated.
