Global Burden of Oral Disorders in Adults Aged ≥65, 1990 to 2021: A Systematic Analysis of Global Burden of Disease Study 2021

Absolute case counts for all oral diseases increased significantly (by 112%-142%) from 1990 to 2021. Although age-standardized disability rates declined for edentulism, dental caries, and other oral disorders, they remained stagnant for periodontal diseases and lip/oral cavity cancer. Socioeconomic disparities persisted or even widened, with disease-specific patterns. Projections to 2035 indicate a growing burden among older populations, highlighting an urgent need for equitable and targeted public health interventions.
