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.

Prevalence of lectures about dental esthetics and female speakers in three Brazilian conferences

“…In 2020, there were 544 authorized courses in the country, which are higher than those observed in more populated countries such as India (313), China (96), and the United States of America (67) 4 , 5 , 6 . Despite the high number of dentists, Brazil presents approximately 45% of its population with some oral disorder 7 , which is a higher rate than that observed for the worldwide population (40%) 8 . Indeed, dentists' distribution in the country is not based on the oral health needs of the population 9 , and most clinicians prefer to work in more profitable private clinics in large cities 10 .…”

The efficacy of combining adjuvants with non‐surgical periodontal therapy in individuals with type 2 diabetes: A Bayesian network meta‐analysis

“…Severe periodontitis prevalence worldwide has been estimated to be 11% in the general population (Kassebaum et al, 2014) and 68% among people with diabetes (Zheng et al, 2021). Severe periodontitis can significantly impair function, aesthetic appearance, and overall quality of life (Bernabe et al, 2020;GBD, 2018;Hugo et al, 2022). Non-surgical and surgical periodontal treatments effectively treat periodontitis and reconstruct the periodontium.…”

The alcohol harm paradox and tooth loss among Brazilian older adults

“…In this respect, tooth loss is an important public health problem (Peres et al, 2019), especially among older adults and the most deprived groups, given their insufficient access to dental care and health resources compared to younger (Xu et al, 2020) and least disadvantaged counterparts (Elani et al, 2017), respectively. Tooth loss is associated with (Cheng et al, 2018) and causes disability levels comparable (Hugo et al, 2022) to other important chronic diseases, aspect that highlights the critical need for more research to identify modifiable factors associated with this condition, particularly among vulnerable groups. In Brazil, 22 million people are affected by edentulism (Hugo et al, 2022) and those aged from 65 years have an average of approximately 25 missing teeth (Brazilian Ministry of Health, 2012).…”
