Oral disorders among older Chileans: prevalence, incidence, and years lived with disability / Prevalência, incidência e anos vividos com incapacidade por doenças bucais no Chile

OBJECTIVE: Prior epidemiological surveys revealed that Chile experiences a high burden of oral diseases. However, no prior study has reported estimates of untreated dental caries, periodontitis, and edentulism over a three-decade period for the country. Using estimates of the Global Burden of Diseases Study (GBD) 2019, the objective of this study is to report the trends of prevalence, incidence, and years-lived with disability (YLDs) due to untreated dental caries, periodontitis, and edentulism in Chilean older adults between 1990 and 2019. METHODS: Estimates of prevalence, incidence, and YLDs due to dental caries, periodontitis, and edentulism were produced for Chile, by age and sex, between 1990 and 2019, using Dismod-MR 2.1. Trends of oral disorders were analyzed using generalized linear regression models applying the Prais-Winsten method. RESULTS: Untreated dental caries and periodontal disease showed an increase in prevalence and YLDs, whereas edentulism prevalence, incidence, and YLDs decreased in all older adults age groups. The incidence of dental caries decreased in the younger groups and increased in the older age groups; while the incidence of periodontal disease increased in the younger and decreased in the older age groups. CONCLUSIONS: Overall, the burden of oral diseases in older Chileans increased between 1990 and 2019. This was particularly relevant for untreated caries and periodontal disease. Future estimates of oral diseases burden in Chile require concerted efforts to produce national health surveys that incorporate oral diseases metrics. These estimates are essential to inform policy formulation, implementation and evaluation. (AU)

OBJETIVO: Pesquisas epidemiológicas anteriores revelaram que o Chile apresenta uma elevada carga de doenças bucais. No entanto, nenhum estudo anterior relatou estimativas de cárie dentária não tratada, periodontite e edentulismo ao longo de um período de três décadas para o país. Usando estimativas do Global Burden of Diseases Study (GBD) 2019, o objetivo deste estudo é relatar as tendências de prevalência, incidência e anos vividos com incapacidade (YLDs) devido a cárie dentária não tratada, periodontite e edentulismo em idosos chilenos entre 1990 e 2019. METODOLOGIA: Estimativas de prevalência, incidência e YLDs devido à cárie dentária, periodontite e edentulismo foram produzidas para o Chile, por idade e sexo, entre 1990 e 2019, usando o Dismod-MR 2.1. Tendências de distúrbios bucais foram analisadas usando modelos de regressão linear generalizada aplicando o método Prais-Winsten. RESULTADOS: A cárie dentária não tratada e a doença periodontal mostraram um aumento na prevalência e nos YLDs, enquanto a prevalência, incidência e YLDs do edentulismo diminuíram em todas as faixas etárias de idosos. A incidência de cárie dentária diminuiu nos grupos mais jovens e aumentou nos grupos etários mais velhos; enquanto a incidência de periodontite aumentou nos grupos mais jovens e diminuiu nos grupos etários mais velhos. CONCLUSÕES: No geral, a carga de doenças bucais em idosos chilenos aumentou entre 1990 e 2019. Isso foi particularmente relevante para cárie não tratada e periodontite. As estimativas futuras da carga de doenças bucais no Chile exigem esforços concentrados para produzir pesquisas nacionais de saúde que incorporem métricas de doenças bucais. Essas estimativas são essenciais para informar a formulação, implementação e avaliação de políticas. (AU)

Prevalence, incidence, and years-lived with disability due to oral disorders in Brazil: an analysis of the Global Burden of Disease Study 2019

Abstract INTRODUCTION Epidemiological surveys revealed that Brazil has a high burden of oral diseases. However, no prior study has reported estimates of untreated dental caries, periodontitis, and edentulism over a three-decade period. The objective of this study is to report the trends of prevalence, incidence, and years-lived with disability (YLDs) due to untreated dental caries in primary and permanent teeth, periodontitis, and edentulism in Brazil between 1990 and 2019. METHODS Estimates of prevalence, incidence, and YLDs due to dental caries in primary and permanent teeth, periodontitis, and edentulism were produced for Brazil, by sex and age, between 1990 and 2019, using Dismod-MR 2.1, as part of the Global Burden of Disease Study 2019 (GBD 2019). Trends of oral disorders were analyzed using generalized linear regression models applying the Prais-Winsten method. RESULTS Almost 100 million Brazilians presented at least one oral disorder in 2019, which was equivalent to a prevalence of 45.3%. All oral diseases combined ranked eighth among all causes of disability, causing more than 970,000 YLDs. Untreated dental caries in primary teeth were estimated to affect 13.5 million children, and untreated dental caries in permanent teeth affected more than 52 million people. Periodontitis affected 29.5 million people, and edentulism affected almost 22 million. The generalized linear regression models revealed a trend of stability of oral disorders between 1990 and 2019. CONCLUSIONS The burden of oral diseases in Brazil is extremely high. Oral disorders, edentulism in particular, caused disability at levels that are comparable to other important chronic diseases.
