Burden of severe periodontitis and edentulism in 2021, with projections up to 2050: The Global Burden of Disease 2021 study

To (i) assess the prevalence, incidence, and burden of severe periodontitis and edentulism in 2021, and (ii) forecast their rates in 2050.

Prevalence, incidence, and Years Lived with Disability (YLDs) for severe periodontitis and edentulism in 2021 were gathered globally, covering 204 countries, seven super regions, and 21 regions from the Global Burden of Disease (GBD) 2021 study. Prevalence, incidence, and YLDs due to periodontitis and edentulism to 2050 were projected using mixed-effects models with the socio-demographic index as the main covariate.
