Burden of oral disorders in the U.S. from 1990 to 2023: Findings from GBD study

Objectives : There is no comprehensive study comparing the burden of different oral diseases across states, years, and different demographics in the United States (US). Therefore, to address this gap, we aimed to evaluate the burden of oral disorders in the US and its states from 1990 to 2023. Methods : We used the Global Burden of Disease (GBD) 2023 data to evaluate the burden of oral disorders in the USA from 1990 to 2023 in different age groups, sexes, states, and years. We aim to report the incidence, prevalence, and Disability-Adjusted Life Year (DALY) rates of caries of deciduous teeth, caries of permanent teeth, periodontal diseases, edentulism, and other oral disorders, accompanied by 95% uncertainty intervals (UIs). Results : From 1990 to 2023, age-standardized prevalence, incidence, and DALY rates of total oral disorders in the USA declined slightly by 2.3%, 0.14%, and 4.82%, respectively. Among all oral disorders, caries of permanent teeth had the highest age-standardized prevalence and incidence rates, while edentulism accounted for the highest DALY burden in both 1990 and 2023. Males had higher incidence and prevalence, whereas females had higher DALY rates across allthese34 years. The burden of oral disorders varied by age and state, with older adults and states such as West Virginia showing the highest DALY rates. Conclusions : Although the decline in the burden of oral disorders in the US over the past decades was a promising trend, the recent increases are concerning and warrant attention from policymakers.
