Singh A, Purohit BM, Purohit A. Risk factors and associated pathway for rural and urban unmet dental prosthetic needs among older adults in Central India. SPECIAL CARE IN DENTISTRY 2024; 44:1182-1190. [PMID: 38302807 DOI: 10.1111/scd.12967] [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: 06/30/2023] [Revised: 01/18/2024] [Accepted: 01/20/2024] [Indexed: 02/03/2024]
Abstract
AIM This study was undertaken to evaluate the risk factors and associated pathways for unmet dental prosthetic needs among older adult population in Central India. METHODS A total of 11,145 randomly selected older adults participated in the study; 4613 from urban region and 6532 form rural region. Oral examinations were conducted at individual households for recording dental caries, periodontal disease, prosthetic status and needs. Structural Equation Modelling (SEM) was used to examine relationship between a set of exogenous variables and unmet dental prosthetic needs with variables that remained significant in the adjusted multilevel logistic model. Path coefficients were calculated for all variables with 95% confidence interval. Goodness of fit of the model was assessed by several indices. RESULTS A total of 8433 (75.7%) participants had never visited a dentist and 9139 (82%) had unmet dental prosthetic needs. Dental caries was observed among 3207 (69.5%) and 4644 (71.1%) study participants from urban and rural regions respectively (p < .05). Low utilization of dental services was associated with high dental prosthetic needs in upper arch and lower arch (PC = -0.05, 0.001) and DMFT was associated with lower utilization of dental services (PC = -0.09, 0.001). DMFT was also associated with age, annual income, level of education, paternal education, type of family, tobacco consumption and CPI score in the hypothesized model. The fit indices used indicated that the model was adequate. CONCLUSIONS Dental prosthetic needs in the proposed pathway model was associated with low utilization of dental services, dental caries, periodontal disease and other socio-demographic factors.

Bomfim RA, de Lucena EHG, Cavalcanti YW, Celeste RK. Racial inequality in complete dental prosthesis delivered: can public services reduce inequities? Clin Oral Investig 2023; 28:17. [PMID: 38135856 DOI: 10.1007/s00784-023-05432-1] [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: 08/10/2023] [Accepted: 11/20/2023] [Indexed: 12/24/2023]
Abstract
OBJECTIVES To investigate the association between access and delivery of complete dental prosthesis according to the proportion of the black population in Brazilian municipalities and to oral health policies. MATERIALS AND METHODS Ecological data from 2017 to 2021 relating to the delivery of complete dentures stratified by race was collected in all Brazilian cities. We calculated a racial inequality indicator by subtracting the percentage of the black population from the percentage of complete dental prostheses that were delivered to blacks in each municipality. Logistic and linear regression models were carried out. RESULTS We found that 49.2% (2737) of municipalities delivered complete prostheses. The service was more frequently available in municipalities where black individuals made up 20-80% (odds ratio [OR] = 1.45, 95% confidence interval [CI] 1.15; 1.81), those with dental specialty centers (DSC) (OR = 3.04, 95%CI 2.50; 3.68), and those with more oral health teams (OHTs) (OR = 3.43, 95%CI 2.81; 4.18). Where dental prostheses were available, racial inequities favored the white population by 7.7 percentage points (p < 0.01). Increased inequality was observed in municipalities with more OHTs and/or a higher proportion of black individuals (>80%). CONCLUSIONS Although municipalities with a DSC, and with more OHTs offer better access to complete dental prosthesis for blacks, racial inequality still impacts the delivery of the service. Primary and secondary healthcare services may even exacerbate this. CLINICAL RELEVANCE Policymakers should monitor racial inequities in healthcare services. The currently unmet needs of black people are critical, especially in cities with more OHTs and/or increased proportions of black people.

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.

Abstract
PURPOSE The aim of this study was to evaluate the flexural strength of a 3D-printed denture base resin (Cosmos Denture), after different immediate repair techniques with surface treatments and thermocycling. MATERIALS AND METHODS Rectangular 3D-printed denture base resin (Cosmos Denture) specimens (N = 130) were thermocycled (5,000 cycles, 5℃ and 55℃) before and after the different repair techniques (n = 10 per group) using an autopolymerized acrylic resin (Jet, J) or a hard relining resin (Soft Confort, SC), and different surface treatments: Jet resin monomer for 180 s (MMA), blasting with aluminum oxide (JAT) or erbium: yttrium-aluminum-garnet laser (L). The control group were intact specimens. A three-point flexural strength test was performed, and data (MPa) were analyzed by ANOVA and Games-Howell post hoc test (α = 0.05). Each failure was observed and classified through stereomicroscope images and the surface treatments were viewed by scanning electron microscope (SEM). RESULTS Control group showed the highest mean of flexural strength, statistically different from the other groups (P < .001), followed by MMA+J group. The groups with L treatment were statistically similar to the MMA groups (P > .05). The JAT+J group was better than the SC and JAT+SC groups (P < .05), but similar to the other groups (P > .05). Adhesive failures were most observed in JAT groups, especially when repaired with SC. The SEM images showed surface changes for all treatments, except JAT alone. CONCLUSION Denture bases fabricated with 3D-printed resin should be preferably repaired with MMA+J. SC and JAT+SC showed the worst results. Blasting impaired the adhesion of the SC resin.

Community Dent Oral Epidemiol 2022; 51:557-564. [PMID: 35569009 DOI: 10.1111/cdoe.12749] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2021] [Revised: 03/28/2022] [Accepted: 04/24/2022] [Indexed: 12/29/2022]
Abstract
OBJECTIVES Studies suggest that wearing dentures to restore missing teeth can have a positive impact on health status. However, income inequalities in denture wearing exist. The aim of this study was to investigate how differing co-payment rates under the current Japanese Universal Health Insurance Coverage System affect income inequalities in denture non-use among older adults with severe tooth loss. METHODS This cross-sectional study used data from the 2019 Japan Gerontological Evaluation Study (JAGES). Self-administered questionnaires were mailed to 345 356 independent people who did not receive long-term care insurance benefits and were aged ≥65 years. The dependent variable was denture non-use, and the independent variable was the equivalent annual household income. The Slope Index of Inequality (SII) and Relative Index of Inequality (RII) were used with regression-based approaches to determine both absolute and relative inequalities in denture non-use by co-payment rates. The covariates were sex, age, years of education, number of teeth and comorbidities. RESULTS Of the 240 889 responses received (response rate =69.9%), we analysed 21 594 participants who fulfilled the inclusion criteria. The mean age was 72.8 years (standard deviation =4.1), and 57.6% were men. For 30 per cent, 20 per cent and 10 per cent co-payment rates, the percentages of people who did not use dentures and had severe tooth loss (≤9 teeth) were 18.3%, 13.3%, and 8.5%, respectively. All analyses confirmed significant inequalities in denture non-use. The lower the co-payment rate, the smaller the inequalities. SIIs for each co-payment rate were as follows: 30 per cent =13.35% (95% confidence interval [CI] = 9.61-17.09); 20 per cent =7.85% (95% CI = 4.88-10.81); and 10 per cent =4.85% (95% CI = 2.55-7.16). Inclusion of interaction term between income and co-payment rate significantly lowered the inequalities by co-payment rate in logistic regression analysis and SII. For RII, although the interaction was not statistically significant, a similar trend was observed. CONCLUSIONS Income inequalities in denture use existed among older adults with severe tooth loss in Japan, and the inequalities appeared to be greater when the co-payment rate was higher.

Clin Oral Investig 2022; 26:4633-4645. [PMID: 35239016 DOI: 10.1007/s00784-022-04432-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2021] [Accepted: 02/19/2022] [Indexed: 11/27/2022]
Abstract
OBJECTIVE To investigate the incidence and risk factors for non-adaptation of the conventional mandibular complete denture (CMCD). MATERIALS AND METHODS A total of 108 edentulous patients were rehabilitated with complete dentures (CDs) and followed up at 3- and 6-month intervals. Adaptation was confirmed based on chewing, phonetics, and comfortable swallowing with the CDs. The risk factors among sociodemographic and patient-centered factors were analyzed. Statistical analyses included the chi-square test and then a multivariate analysis. RESULTS After 3 months, 38.0% of patients showed non-adaptation to CMCDs. Non-adaptation was significantly associated with the absence of previous mandibular denture experience (p = 0.042), ulcerations after 15 days of rehabilitation (p < 0.001), and a reduced posterior mandibular ridge (p = 0.035). After 6 months, this incidence decreased to 14.1%. The factors associated with non-adaptation were ulcerative lesions after 15 (p < 0.001) and 30 (p < 0.001) days of the delivery of CDs and the non-regular use of mandibular CDs (p < 0.001). CONCLUSION The incidence of non-adaptation was higher after 3 months, with reduction after 6 months. Sociodemographic variables did not influence the adaptation. After 3 months, the absence of previous experience, traumatic ulcers, and reduced mandibular ridges hindered the adaptation of patients to mandibular CDs. After 6 months, only the occurrence of ulcerative lesions and non-regular wear of dentures were risk factors for non-adaptation. CLINICAL RELEVANCE A considerable number of patients have difficulties in adapting to the mandibular dentures. Identifying the factors of non-adaptation of the dentures will contribute to increasing the predictability of this critical adaptation period.

Systematic Review of the Literature on Dental Caries and Periodontal Disease in Socio-Economically Disadvantaged Individuals. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph182312360.

Abstract
Dental caries and periodontal disease represent a health problem and a social cost for the entire population, and in particular for socio-economically disadvantaged individuals who are less resistant to disease. The aim of this review is to estimate the prevalence and severity of the two dental pathologies, caries and periodontal disease, in the different classes of socio-economically disadvantaged subjects and to understand which of them are most affected. A systematic search of the literature was performed in MEDLINE (via PubMed), EMBASE and Web of Science after establishing a suitable search strategy for each database, using keywords related to socio-economically vulnerable classes and health outcomes. Socio-economically disadvantaged individuals are more susceptible to tooth decay and periodontal disease (with relative tooth loss) than non-vulnerable people. Additionally, when multiple vulnerabilities are combined in the same subject, these oral diseases worsen. There is no type of vulnerability more affected by caries and periodontitis than others, since overall they all have severe disease indices. The data from this systematic literature review might be useful for health policy makers looking to allocate more resources and services to socially disadvantaged individuals, resulting in making them more resilient to oral disease due to their social marginalization.

Abstract
BACKGROUND Population-based studies assessing the factors associated with use of and need for dental prosthesis among older adults are scarce. OBJECTIVE To evaluate the use of and need for dental prosthesis and associated factors in the older adult population of a southern city of Brazil. MATERIAL AND METHODS A cross-sectional study, involving community-dwelling older adults (≥60 years), was performed. A probabilistic per cluster sampling was used, and 282 participants from Veranópolis, Brazil, were included. A clinical oral health examination was performed, and a structured questionnaire was applied. Bivariate and multivariate analyses were performed to verify associations using Poisson regression with robust variance. RESULTS The prevalence of use of dental prosthesis was 87.2% (n = 246), while the prevalence of need for dental prosthesis was 27% (n = 76). Older adults with medium/high levels of education had 17.8% (P = .019) lower prevalence ratio (PR) for use of dental prosthesis. Unmarried and retired older adults had, respectively, 11.1% (PR:1.111; 95%CI:1.022-1.207) and 19.5% (PR:1.195; 95%CI:1.009-1.415) higher PR for use of prosthesis. Those without access to dental care had 11.8% (P = .012) higher PR for use of dental prosthesis. Older adults living in rural areas had 64.7% (PR:1.647; 95%CI:1.079-2.514) higher PR of need for dental prosthesis. CONCLUSION High and low prevalence of use of and need for dental prosthesis, respectively, were detected in this sample. Level of education, marital status, retirement status and access to dental care were associated with the use of dental prostheses. However, only residence area was associated with the need for oral rehabilitation.

Abstract
BACKGROUND Population ageing in Brazil is rapid and is likely to place additional pressure over the Brazilian public health system. OBJECTIVE This study aims to examine the factors associated with utilisation of dental services in the previous year among a representative sample of older adults from São Paulo, Brazil. METHODS The sample included 5951 older adults who participated in the SBSP-15 study, an epidemiological survey conducted in 2015 in the State of São Paulo, Brazil. The outcome "utilisation of dental services" was defined as having visited a dentist in the previous year. Chi-square tests were employed in the bivariate analyses and Poisson regressions with robust variance in the multilevel analysis. RESULTS Only 30.5% of the participants had their last dental appointment within the previous year. Number of teeth and dental pain presented the strongest effects on the investigated outcome. Education, income, age, ethnicity, living alone, higher Family Health Strategy coverage and the Metropolitan area were associated with having visited a dentist in the previous year. Older adults who rated their oral health as positive did not report treatment need nor prosthodontic need, presented negative oral health-related quality of life, had their last dental appointment in the public health system and sought treatment due to pain or extraction also were more likely to report the utilisation of dental services in the previous year. CONCLUSION Regional, sociodemographic and subjective factors are associated with utilisation of dental services in the previous year among the elders from the State of São Paulo, Brazil.

The Impact of Expanded National Health Insurance Coverage of Dentures and Dental Implants on Dental Care Utilization among Older Adults in South Korea: A Study Based on the Korean Health Panel Survey. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17176417. [PMID: 32899291 PMCID: PMC7504266 DOI: 10.3390/ijerph17176417] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 08/10/2020] [Revised: 08/29/2020] [Accepted: 09/01/2020] [Indexed: 11/19/2022]
Abstract
In South Korea, the National Health Insurance Service (NHIS) began its coverage of dentures and dental implants for older people in 2012 and 2014, respectively. This study aimed to investigate the impact of these policies on dental care utilization among people aged 65 years or older according to their sociodemographic characteristics. Data were collected from the Korea Health Panel Survey (KHP; years 2012 and 2015). The statistical significance of the relationships between sociodemographic characteristics and the use of outpatient dental care, denture, and dental implant were analyzed. Results showed an increase of 5.7%, 1.4%, and 2.8% in the use of outpatient dental care, denture, and dental implant, respectively, over the course of three years. Including dentures increased its use by 2.5–3.7 times among people aged 70 years or older. Including dental implants alleviated the disparities among older adults based on age groups and duration of education, except those among uneducated people; however, it caused inequity according to household income. Some Korean older adults remain neglected from the benefits of the expanded NHIS. Therefore, older adults’ access to dental care should be enhanced by the implementation of policies to promote oral health care utilization, dental prosthetic services, and older adults’ insurance coverage.

This study aimed to test the association of contextual and individual socioeconomic status with tooth loss among Brazilian elderly people aged 65–74 years. Data from 5435 elderly participants from the Brazilian National Oral Health Survey (2010) were linked to city-level data for 27 state capitals and the Federal District. Tooth loss was clinically assessed according to the number of missing natural teeth. Contextual social variables included Human Development Index income (HDI-income) and HDI-education. Individual socioeconomic measures were monthly family income and years of schooling. Covariates included sex, skin colour, number of residents per room and number of goods. Multilevel Negative Binomial regression models were used to estimate rate ratios (RR) and 95% confidence intervals between contextual and individual variables and tooth loss. Contextual and individual income and education measures were consistently associated with tooth loss. Elderly people living in cities with low HDI-income and low HDI-education were respectively 21% and 33% more likely to present tooth loss. Cross-level interaction suggested that the relationship of lower income and lower schooling with tooth loss is different across levels of city-level income and city-level education inequality, respectively. Public policies aiming to reduce the income and education gaps and preventive dental interventions are imperative to tackle tooth loss among elderly people.

Lee CY, Lee YH. Measurement of Socioeconomic Position in Research on Cardiovascular Health Disparities in Korea: A Systematic Review. J Prev Med Public Health 2019; 52:281-291. [PMID: 31588697 PMCID: PMC6780291 DOI: 10.3961/jpmph.19.094] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2019] [Accepted: 08/05/2019] [Indexed: 01/17/2023] Open
Abstract
OBJECTIVES The validity of instruments measuring socioeconomic position (SEP) has been a major area of concern in research on cardiovascular health disparities. The purpose of this systematic review is to identify the current status of the methods used to measure SEP in research on cardiovascular health disparities in Korea and to provide directions for future research. METHODS Relevant articles were obtained through electronic database searches with manual searches of reference lists and no restriction on the date of publication. SEP indicators were categorized into compositional, contextual, composite, and life-course measures. RESULTS Forty-eight studies published from 2003 to 2018 satisfied the review criteria. Studies utilizing compositional measures mainly relied on a limited number of SEP parameters. In addition, these measures hardly addressed the time-varying and subjective features of SEP. Finding valid contextual measures at the organizational, community, and societal levels that are appropriate to Korea's context remains a challenge, and these are rarely modeled simultaneously. Studies have rarely focused on composite and life-course measures. CONCLUSIONS Future studies should develop and utilize valid compositional and contextual measures and appraise social patterns that vary across time, place, and culture using such measures. Studies should also consider multilevel influences, adding a focus on the interactions between different levels of intertwined SEP factors to advance the design of research. More attention should be given to composite and life-course measures.
