Background The association between periodontitis and immuno‐mediated inflammatory diseases has been widely studied and recognized each more over the past few years. The aim of this study was to evaluate the potential association between psoriasis and periodontitis, as well as the influence of risk variables in this association. Methods This case‐control study included 756 individuals, 397 with psoriasis, and 359 controls. A full‐mouth periodontal examination was performed, recording therefore plaque index, probing depth, clinical attachment level, and bleeding on probing. The influence of risk variables was tested by univariate analysis and multivariate logistic regression. Results A high prevalence of periodontitis was observed among cases (46.1%) when compared to controls (33.1%). Individuals with psoriasis presented a 1.72 higher chance of having periodontitis than controls (OR = 1.72; 95% CI 1.28–2.32; p < 0.001) in the univariate analysis, but with no significance in the multivariate model. The prevalence of periodontitis increased significantly according to the severity of psoriasis [mild form (44.4%); moderate (46.3%); and advanced (47.1%)] when compared to the control group (33.1%). The final multivariate logistic model showed that the number of teeth (OR = 1.08; 95% CI 1.01–1.14; p = 0.018), smoking (OR = 1.91; 95% CI 1.19–3.07; p = 0.008), and body mass index (OR = 1.13; 95% CI 1.11–1.16; p < 0.001) remained significantly associated with the occurrence of periodontitis. Conclusions The prevalence of periodontitis was higher in individuals with psoriasis than in controls. Severity of psoriasis also presented a strong relationship with all periodontal clinical parameters.
