Abstract
BACKGROUND
Studies focusing on the relationship between periodontitis and systemic diseases have suggested a possible association between these two chronic and inflammatory disorders. We aimed to comparatively investigate the salivary oxidative status, biomarker levels, clinical findings, and the microbial load on subgingival biofilm samples in psoriasis patients and controls.
METHODS
Forty participants were allocated into four groups as follows: (1) systemically and periodontally healthy (C group); (2) systemically healthy with periodontitis (P group); (3) psoriasis (Ps) and periodontally healthy (Ps-C group); and (4) Ps with periodontitis (Ps-P group). Subgingival biofilm samples were obtained to detect the periodontopathogenic agents by Real-time PCR (qPCR). The total antioxidant status (TAS) (mmol/l), total oxidant status (TOS) (μmol/l), and arylesterase (ARE) activity (U/L) were analyzed using saliva samples.
RESULTS
The level of TOS and oxidative stress index (OSI) were significantly higher in patients with Ps-P and P compared to controls (P = 0.001, and P ˂ 0.001, respectively). ARE levels were higher in controls compared to Ps and P (P ˂ 0.001). The prevalences of bacteria detected in subgingival biofilm samples were similar between all groups (P > 0.05).
CONCLUSIONS
This study reported that psoriasis may amplify TOS and OSI, and the co-existence of psoriasis and periodontitis may aggravate oxidative stress.
