The Effects of Chronic Periodontitis and Its Treatment on the Subsequent Risk of Psoriasis
Background:
Although psoriasis and *chronic periodontitis (CP) may share an underlying immune dysregulation as part of their pathologies, only one small-scaled cross-sectional pilot study has investigated the potential association between CP and psoriasis to date.
Objective:
This study aimed to investigate the subsequent risk for psoriasis following a diagnosis with CP by utilizing a cohort study design and population-based dataset in Taiwan.
Methods:
In total, 115,365 patients with CP were included in the study cohort and 115,365 patients without CP were included in the comparison cohort. We individually tracked each patient for a five-year period to identify those who had subsequently received a diagnosis of psoriasis. A Cox proportional hazards regression was performed to compute the five-year risk of subsequent psoriasis following a diagnosis of CP.
Results:
We found that the incidence rate of psoriasis during the five-year follow-up period was 1.88 (95% CI=1.77-1.99) per 1,000 person-years in patients with CP and 1.22 (95% CI=1.14-1.32) per 1,000 person-years in comparison patients. After censoring those who died during the follow-up period, and adjusting for monthly income and geographic region, compared with comparison patients, the HR of psoriasis for patients with CP was 1.52 (95% CI=1.38-1.70). Furthermore, the study subjects who had undergone a gingivectomy or periodontal flap operation only had a slightly higher adjusted risk of psoriasis than comparison patients (HR=1.26).
Conclusions:
This study detected an increased risk for psoriasis among patients suffering from CP. Treatment for CP attenuated, but did not nullify, the risk for subsequent psoriasis.

*Chronic periodontitis is a common disease of the oral cavity consisting of chronic inflammation of the periodontal tissues.
Symptoms may include: Redness or bleeding of gums while brushing teeth, Gum swelling that recurs, Halitosis, Gingival recession, Deep pockets between the teeth and the gums, Loose teeth.
