Summary

Periodontitis (PD), a chronic inflammatory disease which results in irreversible attachment loss, bone destruction and, if left untreated, tooth loss. Rheumatoid arthritis (RA), is an autoimmune disease characterized as a chronic inflammatory disorder leading to synovial inflammation and destruction of cartilage and bone. RA and PD which are commonly seen in elderly have many similarities in terms of pathophysiology and clinical progression. Previous findings from the investigators reported that inflamed periodontal tissues of RA subjects with PD are a potential site for post translational modification of proteins as there was increase in presence of citrullinated and carbamylated proteins in gingival tissues. Autoantibodies to these proteins have been reported to be involved in loss of immune tolerance which leads to RA and its progression. Currently there are gaps in our knowledge concerning the effect of nonsurgical periodontal therapy (NSTP), comprising oral hygiene instructions, scaling and root surface debridement on presence of these autoantibodies and inflammatory outcomes of RA. It is hypothesized that reduction in periodontal inflammation may concurrently reduce the systemic inflammatory load which is responsible in perpetuating RA joint inflammation. Here, the investigators propose to perform a randomized, controlled, single-blinded study on RA subjects with stage 2 or 3 periodontitis to assess the effect of NSTP on the reduction of these autoantibodies and inflammatory mediators as well as RA related disease activity measures such as ESR, CRP and Disease Activity Score 28-joint count (DAS28). The investigators will also assess changes in subgingival microbiota associated with RA-PD in response to NSTP using next generation sequencing. This study will help determine if RA individuals could benefit from early and appropriate NSPT, thus reducing periodontal inflammation and a similar impact on RA disease could be expected. This will ultimately improve patients' quality of life and reduce societal burden related to increased patient discomfort and treatment costs.
