Global and regional progress towards reduced burden of oral conditions between 2019 and 2023: a systematic analysis for the Global Burden of Disease Study 2023

Globally, the age-standardised prevalence of main oral conditions declined (−1·55% [95% uncertainty interval −2·32 to −0·82]) between 2019 and 2023, but global cases increased by 3·07% (2·32 to 3·75), from 3·62 billion (3·35 to 3·95) to 3·73 billion (3·45 to 4·06). Among complementary indicators, reductions in age-standardised prevalence were observed for untreated caries in permanent teeth (−1·99% [−2·49 to −1·40]) whereas the age-standardised incidence of lip and oral cavity cancer increased (8·35% [0·13 to 16·32]), as did the age-standardised prevalence of orofacial clefts (2·25% [0·77 to 3·83]). Progress was heterogeneous across GBD super-regions, with south Asia having the largest reductions in the age-standardised prevalence of main oral conditions (−3·34% [−4·95 to −1·80]) and untreated caries in deciduous teeth (−9·09% [−17·62 to −0·08]). Sub-Saharan Africa showed the largest increase in prevalent cases of main oral conditions (9·51% [8·09–10·94]) and age-standardised incidence of lip and oral cavity cancer (14·86% [1·19–32·45]). The high-income super-region had an increase in the age-standardised prevalence of main oral conditions (1·24% [0·56–1·96]) and untreated caries in deciduous teeth (9·21% [6·60–11·89]).
