Aim: The current study aims to determine whether there is a relationship between Rheumatoid arthritis disease activity and severity of chronic periodontitis in the study population. Methods: 100 patients aged 20-70 years, diagnosed with Rheumatoid arthritis and Chronic periodontitis were selected for the study. The rheumatoid disease activity was assessed using DAS 28 and severity of periodontitis was classified based on clinical attachment loss. Physical disability was elicited using Indian Health Assessment Questionnaire and Oral hygiene status was measured using Oral Hygiene Index. Results: Among the 100 Rheumatoid Arthritis patients with periodontitis, 11 were males (11%) and 89 were females (89%). Rheumatoid disease activity showed no correlation with periodontal disease severity (r value 0.01,p value__ampersandsigngt;0.05) . Functional disability of the patients showed a significant correlation with their oral hygiene status (r value 0.232,p value__ampersandsignlt;0.05). The number of missing teeth showed significant correlation with clinical attachment loss (r value 0.511,p value__ampersandsignlt;0.001) and functional disability(r value 0.259,p value__ampersandsignlt;0.001). Conclusion: It can be concluded from the results of our study that severe rheumatoid disease activity impairs the functional ability of the patients in maintaining good oral hygiene which in turn leads to periodontitis
