The global burden of periodontal diseases in 204 countries and territories from 1990 to 2019

AimsThe aim of this study was to report the incidence, prevalence, and disability-adjusted life-years (DALYs) of periodontal diseases during the period 1990-2019. MethodsData on periodontal diseases were retrieved from the Global Burden of Diseases, Injuries, and Risk Factors study (GBD) 2019. The estimated annual percentage changes were calculated to evaluate the changing trend of age-standardized incidence, prevalence, and DALY rates related to periodontal diseases. ResultsGlobally, there were 1,087,367,744.0 cases with 91,518,820.6 new incidence and 7,090,390.3 DALYs of periodontal diseases in 2019, almost twice as many as in 1990. Moreover, the pace of increase in age-standardized incidence, age-standardized prevalence, and age-standardized DALY rates had accelerated during the 1990-2019 time period, with EAPC of 0.29 (95% CI, 0.22 to 0.35), 0.34 (95% CI, 0.26 to 0.43), and 0.35 (95% CI, 0.27 to 0.44) separately. The corresponding age-standardized percentage changes were more pronounced in females, Southeast Asia, and low-middle SDI regions. Western Sub-Saharan Africa was the high-risk area of standardized periodontal diseases burden in 2019, among which Gambia was the country with the heaviest burden. ConclusionThe globally incidence, prevalence, and DALYs of periodontal diseases are substantially increased from 1990 to 2019, which highlights the importance and urgency of periodontal care.

Automated summary

The aim of this study was to report the incidence, prevalence, and disability-adjusted life-years (DALYs) of periodontal diseases during the period 1990-2019. The results showed that globally, the cases, new incidence, and DALYs of periodontal diseases in 2019 were almost twice as many as in 1990. Moreover, the pace of increase in age-standardized incidence, prevalence, and DALY rates had accelerated during the 1990-2019 time period, with more pronounced changes observed in females, Southeast Asia, and low-middle SDI regions. The study highlights the importance and urgency of periodontal care.
