Abstract:

Objective: Periodontal disease is a chronic infection induced by bacteria of the microbial dental plaque. Periodontopathogenic bacteria can affect the formation and severity of psoriasis by both the inflammation they cause and the altered immune response by their products. The aim of this study was to compare the periodontal status between psoriasis-diagnosed individuals and systematically healthy individuals. Materials and Method: Sixty-five patients undergoing psoriasis treatment (test group; 29 females, 36 males) and 100 systemic healthy individuals (control group; 52 females, 48 males) were included in the present study. Clinical and radiographic periodontal assessments were performed. The patients were divided into subgroups according to their periodontal status as gingivitis, stage 1 and stage 2 periodontitis. The dermatological evaluation of the psoriasis patients was performed using the Psoriasis Area and Severity Index (PASI). The data were statistically analyzed considering p<0.05 as significant. Results: The demographic data presented similar age, gender, marital status, and educational status among the groups (p>0.05). Tooth brushing frequency, oral hygiene levels, and socioeconomic status were found higher in the control group (p<0.05). When periodontal clinical parameters were evaluated, probing pocket depth (PPD) and plaque index (PI) were found higher in the test group (p<0.05). Likewise, when the relationship between PASI levels and periodontal clinical parameters were examined in psoriasis patients, PI, GI, and BOP levels were found similar in the patients with 0-5, 5-10 and >10 PASI values (p>0.05). Significant PPD level differences were detected among the PASI subgroups of the psoriasis patients (p<0.05). Conclusion: Psoriasis patients appear to have poor oral hygiene and poor periodontal status compared to systematically healthy individuals. The findings suggest a positive relationship between periodontal disease and psoriasis.
