Aim: To estimate the prevalence of periodontal disease in Brazilian adults and to test its association with skin colour after controlling for socio‐demographic variables. Methods: The periodontal status of 11,342 Brazilian adults was informed by a nationwide oral health survey. Socio‐demographic variables included skin colour, gender, schooling, per capita income, age and geographical region. The association between periodontal disease and skin colour was tested by a logistic regression model, adjusting for covariates. Interactions between skin colour and socio‐demographic variables were tested. Results: The prevalence of periodontal diseases was 9.0% [95% confidence interval (CI) 7.6–10.3]. Lighter‐skinned black people ( pardos ) and dark‐skinned black people ( pretos ) presented higher levels of periodontal disease when compared with white people [odds ratio (OR)=1.5; 95% CI 1.2; 1.8; OR=1.6; 95% CI 1.2; 2.1, respectively] even after controlling for age, gender, schooling, per capita income and geographic region. No interactions were statistically significant. Conclusion: Skin colour was significantly associated with periodontal disease among Brazilian adults after adjustment for socio‐economic and demographic covariates.
