Global smoking‐attributable burden of periodontal disease in 186 countries in the year 2015

Aim We aimed to quantify the smoking‐attributable burden of periodontal disease ( PD ). Methods The association between smoking and PD was evaluated. Population, smoking and PD data from the Global Burden of Disease Study were used, and the burden in different sex and age groups in 186 countries in 2015 calculated, adjusted for PD prevalence and numbers of cigarettes smoked. No adjustment was performed in a sensitivity analysis. Results The global smoking‐attributable burden was 251,160 disability‐adjusted life years ( DALY s; 95% uncertainty interval: 190,721–324,241; sensitivity analysis: 344,041 DALY s) or 38.5 million cases. The burden was lower in females than males, and highest in the age group of the 50‐ to 69‐year‐olds. On super‐regional level, the burden was highest in South‐East Asia, East Asia and Oceania (83,052 DALY s), and high‐income North America and Asia Pacific (55,362 DALY s). On regional level, it was highest in East Asia (70,845 DALY s), South Asia (30,808 DALY s) and North Africa and the Middle East (24,095 DALY s). On national level, it was highest in China (69,148 DALY s), India (29,362 DALY s) and the United States (12,714 DALY s). The relative smoking‐attributable burden ranged between >25% in Suriname and <1% in Chad. Conclusions There is great need to monitor and tackle the smoking‐attributable burden of PD .
