Psoriasis Linked with Periodontal Inflammation

J Invest Dermatol; ePub 2019 Jan 2; Woeste, et al

Psoriasis patients showed significantly higher values for parameters addressing periodontal inflammation, according to a recent study. Therefore, psoriasis management should include regular dental checks on periodontal status and respective treatment where required. Researchers conducted a prospective study comparing psoriasis patients with controls. 100 psoriasis patients presenting at the outpatients’ service of a specialized psoriasis center and 101 non-psoriatic controls were included in 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 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. They found:

  • The matched psoriasis group had significantly higher values of BOP and CPI compared to matched controls.
  • Logistic regression analyses identified significant correlations of the psoriasis group with high BOP and CPI values, not, however, with missing teeth.
