Global burden of periodontal diseases among the working-age population from 1990–2021: results from the Global Burden of Disease Study 2021

Our analysis reveals significant global disparities in periodontal disease burden among the working-age population, with concerning increases in many regions from 1990 to 2021. The disproportionate burden in Low-middle SDI regions and South Asia, coupled with the substantial impact of population growth and aging, highlights the urgent need for targeted interventions. While some countries have achieved remarkable reductions in disease burden, the dramatic increases in others underscore the importance of strengthening preventive oral healthcare systems and addressing socioeconomic determinants. These findings emphasize the need for country-specific strategies, particularly in regions with rising burden, and can inform evidence-based policy making to reduce the impact of periodontal diseases on the global workforce.
