Objective:The aim of this study was to compare the disease activity of rheumatoid arthritis with chronic periodontitis before and after non-surgical periodontal therapy Patients and methods:A total of forty patients will be selected and grouped as follow: Group 1 consists of 20 patients with rheumatoid arthritis and chronic periodontitis (selected from outpatients coming to the Rheumatology and Rehabilitation Department, Faculty of Medicine, Mansoura University). Those patients will be sub grouped as follow: Subgroup A: 10 patients with rheumatoid arthritis without any other systemic disease Subgroup B: 10 patients with rheumatoid arthritis in association with other systemic disease Group 2 consists of 10 patients with rheumatoid arthritis without chronic periodontitis (selected from outpatients coming to the Rheumatology and Rehabilitation Department, Faculty of Medicine, Mansoura University) Group 3 consists of 10 patients with chronic periodontitis (selected from Periodontology and Oral medicine department, Faculty of Dentistry).
Study groups (group 1and 3) had undergone full mouth supra gingival and sub gingival scaling and root planning once a week for 8 weeks. Results:In this study, there was a positive correlation between periodontal parameters, total sub gingival bacterial count and DAS 28 ESR in all studied groups at base line. DAS28 ESR used for measuring RA disease activity showed significantly higher levels in RA patients with chronic periodontitis regarding visual analogue scale (VAS) and ESR . Conclusion:Chronic Periodontitis and Rheumatoid Arthritis share many similarities regarding the clinical, laboratory and microbiological findings. Non- surgical periodontal therapy aids in improvement of the clinical signs and symptoms and a decrease in ESR level in RA patients.
