Global, regional, and national burden of periodontitis from 1990 to 2019: Results from the Global Burden of Disease study 2019

Background To evaluate the prevalence and incidence of periodontitis and associated disability-adjusted life years (DALYs) from 1990 to 2019. Methods We collected data on periodontitis between 1990 and 2019 from the Global Burden of Disease (GBD) 2019 Study. The global prevalence, incidence, and DALYs attributed to periodontitis were analyzed. The age-standardized rate (ASR) and estimated annual percentage changes (EAPCs) were calculated to quantify the burden of the disease and temporal trends. Results The ASR of the prevalence, incidence, and DALYs increased worldwide from 1990 to 2019. In 2019, Western Sub-Saharan Africa carried the heaviest burden of periodontitis, whereas the nation with the highest periodontitis burden was Gambia. The burden of periodontitis was negatively associated with the level of socioeconomic development. Although, the majority of periodontitis burden was observed among those aged 55-59 years, the incidence of periodontitis has shown an increasing trend among younger individuals. Conclusion Periodontitis continues to be a global public health problem. Current prevention and control strategies should be enhanced to prevent an increase in periodontitis.

Automated summary

From 1990 to 2019, the prevalence, incidence, and DALYs of periodontitis have been increasing worldwide. In 2019, Western Sub-Saharan Africa carried the highest burden of periodontitis, and Gambia had the highest burden among nations. The burden of periodontitis was negatively associated with socioeconomic development. Although the majority of periodontitis burden was observed among those aged 55-59 years, the incidence of periodontitis has shown an increasing trend among younger individuals.
