Association Between Apical Periodontitis and Psoriasis Vulgaris

Association Between Apical Periodontitis and Psoriasis Vulgaris: a Cross-sectional Study

The aim of the present cross-sectional study is to assess the presence of AP and caries in psoriasis vulgaris individuals and to examine whether these medications influence these oral conditions. Therefore, 154 patients diagnosed with psoriasis were included in the study and subjected to oral examination to assess for presence of periapical lesions and caries experience.

The aim of the study is to evaluate the prevalence of apical periodontitis (AP) and caries in subjects with psoriasis vulgaris. 152 patients with psoriasis vulgaris were included in the study. The severity and extent of psoriasis were assessed according to The Psoriasis Area Severity Index (PASI), the Body Surface Area (BSA), and the Physician's Global Assessment Scale (PGA). Periapical status was assessed through dental examination and periapical radiographs. Data regarding Periapical Index (PAI), caries experience expressed as the Decayed, Missing, Filled Teeth Index (DMFT), and psoriasis medications were recorded. A predictive logistic regression model for the presence of AP and a linear regression model were then built to relate the severity and extent of AP to the type of drug therapy taken for psoriasis and to the severity and extent of the skin disease.
