Aim To evaluate the association between low bone mineral density (BMD) and severe periodontitis at the end of the second decade of life. Materials and methods This population‐based study analysed 2032 youngers (18–19 years old) of the RPS cohort. BMD of lumbar spine (BMD‐LS) and of the whole body (BMD‐WB) were assessed by dual x‐ray emission densitometry. Low BMD‐LS ( Z ‐score ≤ −2) and low BMD‐WB ( Z ‐score ≤ −1.5) were correlated with severe periodontitis. The extent of periodontal disease was also evaluated as the following outcomes: proportions of teeth affected by clinical attachment loss ≥5 mm and probing depth ≥5 mm. Multivariate models by sex, education, family income, risk of alcohol dependence, smoking, plaque, bleeding index, and body mass index were estimated through logistic regression (binary outcomes) and Poisson regression (continuous outcomes). Results The prevalence of severe periodontitis was 10.97%. Low BMD‐LS (odds ratio [OR] = 2.08, confidence interval [CI] = 1.12–3.85, p = .01) and low BMD‐WB (OR = 1.34, CI = 1.001–1.81, p = .04) were associated with severe periodontitis in the final multivariate models. Low BMD‐LS and BMD‐WB were also associated with a greater extent of periodontitis ( p < .05). Conclusions Low BMD was found to be associated with the severity and extent of periodontitis in adolescents. Adolescents at peak bone mass age presenting low BMD are more likely to be affected by severe periodontitis.
