This study aims to evaluate the relationship between psoriasis, a chronic inflammatory skin disease, and oral health. We will assess the periodontal (gum) condition of patients with psoriasis and examine how it affects their quality of life. A group of psoriasis patients and a control group without psoriasis will undergo oral examinations and complete a short questionnaire. The goal is to better understand whether psoriasis has an impact on gum health and daily well-being.

Inclusion Criteria:

• Participants aged 18 to 65 years
• Clinically diagnosed with active psoriasis
• The presence of at least 12 teeth (excluding third molars)
• Absence of contraindications for periodontal clinical examination

Exclusion Criteria:

• Other dermatological conditions
• Pregnancy or lactation
• Antibiotic use within the last 3 months
• Chemotherapy or radiotherapy within the last year
• Periodontal treatment within the last 6 months

Participants aged 18 to 65 years, clinically diagnosed with active psoriasis, and applying to the Dermatology and Venereal Diseases Department outpatient clinic of the Gulhane Faculty of Medicine were recruited into the test group (n=113). The control group consisted of healthy individuals without any dermatological or systemic diseases (n=113).
