Abstract
BACKGROUND/AIMS: Psoriatic arthritis (PsA) and psoriasis (PS) are chronic inflammatory disorders characterized by significant systemic involvement and comorbidities. This study investigated the occurrence of periodontitis among PS and PsA patients and evaluated its associations with clinical and demographic factors. MATERIALS AND METHODS: Comprehensive evaluations were performed, including the Maastricht Ankylosing Spondylitis Enthesitis Score (MASES) for all participants, along with PsA-specific assessments such as Psoriatic Arthritis and Composite Psoriatic Disease Activity Index (CPDAI). Dermatological and periodontal clinical parameters were recorded. The participants were organized into 2 groups: those with periodontitis and those without. RESULTS: The study included 128 participants: 62 with PS and 66 with PsA. Although the prevalence of periodontitis was higher among PsA patients compared with those with PS (46.97% vs 30.65%), this difference did not reach statistical significance (P = .058). Elevated CPDAI (odds ratio [OR]: 1.38; P = .001) and MASES (OR: 1.39; P < .001) scores were significantly associated with the presence of periodontitis in PsA patients. CONCLUSION: In this study, patients with periodontitis demonstrated higher disease activity scores, underscoring the importance of incorporating periodontal assessment into the multidisciplinary management of psoriatic disease, particularly in patients with active disease.
