Following on from the study I posted in June Psoriasis and oral health here is another study that suggests an increased risk of psoriasis among patients with CP* (Chronic periodontitis)
Background:
Although psoriasis and chronic periodontitis (CP) may share an underlying immune dysregulation as part of their pathologies, to date only one small-scale cross-sectional pilot study has investigated the potential association between CP and psoriasis.
Objectives:
This study aimed to investigate the subsequent risk for psoriasis following a diagnosis of 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 5-year period to identify those who had subsequently received a diagnosis of psoriasis. A Cox proportional hazards regression was performed to compute the 5-year risk of subsequent psoriasis following a diagnosis of CP.
Results:
We found that the incidence rate of psoriasis during the 5-year follow-up period was 1·88 [95% confidence interval (CI) 1·77–1·99] per 1000 person-years in patients with CP and 1·22 (95% CI 1·14–1·32) per 1000 person-years in comparison patients. After censoring those who died during the follow-up period, and adjusting for monthly income and geographical region, compared with comparison patients, the hazard ratio (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 had only a slightly higher adjusted risk of psoriasis than comparison patients (HR 1·26).
Conclusions:
This study detected an increased risk for psoriasis among patients with CP. Treatment for CP attenuated, but did not nullify, the risk for subsequent psoriasis.

*CP (Chronic periodontitis) is a common disease of the oral cavity consisting of chronic inflammation of the periodontal tissues that is caused by accumulation of profuse amounts of dental plaque.

*CP (Chronic periodontitis) is a common disease of the oral cavity consisting of chronic inflammation of the periodontal tissues that is caused by accumulation of profuse amounts of dental plaque.
Signs and symptoms:
- Redness or bleeding of gums while brushing teeth.
- Gum swelling that recurs.
- Halitosis, or bad breath, and a persistent metallic taste in the mouth.
- Gingival recession, resulting in apparent lengthening of teeth.
- Deep pockets between the teeth and the gums.
