Psoriasis is associated with periodontitis, a chronic inflammation of the gingival tissue. However, data about periodontal and dental status of psoriasis patients is sparse. As a result, a prospective study published in the Journal of Investigative Dermatology (2 Jan 2019) comparing dental outcomes of 100 psoriasis patients presenting at the outpatients' service of a specialized Psoriasis-Center, and 101 non-psoriatic controls.
For the study, oral health was assessed using standardized measures including Bleeding on Probing (BOP), Community Periodontal Index (CPI) and dental parameters according to the DMFT-index (cumulative index; teeth registered as decayed (D), missing (M) and filled (F)). For the analysis, a post-matching strategy was applied with 53 pairs of psoriasis and non-psoriatic patients where relevant factors with possible impact on oral health status were considered. Logistic regression analyses were executed on the entire psoriasis and control population.
According to the results. the matched psoriasis group had significantly higher values of BOP and CPI compared to matched controls. Logistic regression analyses also identified significant correlations of the psoriasis group with high BOP and CPI values, not, however, with missing teeth. Psoriasis patients also showed significantly higher values for parameters addressing periodontal inflammation.
According to the authors, psoriasis management should therefore include regular dental checks on periodontal status and respective treatment where required.
