Burden of periodontal diseases in young adults.

We aimed to provide a comprehensive overview of the global burden of periodontal disease among young adults over the period from 1990 to 2019. The analysis considered various factors such as age, sex, country, and Socio-demographic Index (SDI). This study utilized GBD 2019 database to examine the trends in both incidence and disability-adjusted life years (DALY) rates of periodontal diseases among young adults from 1990 to 2019. The data was analyzed based on age-standardization rate. To quantify the temporal and geographic patterns we calculated the estimated annual percentage change (EAPC) and its corresponding 95% confidence interval (CI). The region with the highest age-standardized incidence rate (ASIR) and age-standardized DALY rate was Western sub-Saharan Africa (ASIR: 3949.18, DALY: 336.16) in 2019, while the country with the highest ASIR and age-standardized DALY rate was Qatar (ASIR: 7197.30, DALY: 443.44). the Low SDI area had the highest ASIR and age-standardized DALY rate (ASIR:3469.92, DALY:259.83). The ASIR and age-standardized DALY rate per 100,000 young adults with periodontal diseases exhibited an upward trend from 1990 to 2019, with respective estimated annual percentage changes (EAPC) of 0.41 and 0.45. The high-middle SDI region and middle SDI region both demonstrated a consistent growth pattern, with EAPCs of 0.46 and 0.42, respectively. Over the same time period, Tropical Latin America experienced the largest increase in ASIR and age-standardized DALY rate (EAPCs of 0.55 and 0.63, respectively), while Qatar saw the highest EAPCs in both ASIR (1.55) and age-standardized DALY rate (1.44). The ASIR and age-standardized DALY rate of periodontal disease exhibited a consistent upward trajectory from 1990 to 2019.
