Abstract Aim The rising prevalence of periodontitis imposes substantial burdens on individuals and society. Identifying environmental risk factors for periodontitis may contribute to tackling the global public health burden of it. This study aimed to assess the association between long‐term exposure to PM 2.5 and periodontitis in a nationally representative population from China. Materials and Methods In this multi‐centre cross‐sectional study of 372 communities in 31 provinces of Mainland China, we used data from the Fourth National Oral Health Survey of China in 2015–2016, in combination with high‐resolution gridded concentrations of fine particulate matter (PM 2.5 ). Logistic regression was applied to assess the relationship between long‐term PM 2.5 exposure and the risk of periodontitis. In addition, we examined whether the association varied by individual characteristics, and estimated the exposure–response relationship and the risk of damaged tooth in each tooth quadrant. Results A total of 8391 participants from 96 cities were diagnosed with periodontitis, accounting for 60.04% (8391/13,459) of the participants. For each 10 μg/m 3 increment in 1‐, 3‐ and 5‐year average concentrations of PM 2.5 , the risk of total periodontitis increased by 9.0% (95% confidence interval: 6.0%, 12.0%), 8.0% (6.0, 11·0) and 7.0% (5.0, 10.0), respectively. Mild periodontitis was more strongly associated with PM 2.5 exposure than moderate and severe periodontitis. The teeth in the lower ant...
