Background: Evidence have been proposed a positive association between severity of Periodontitis and Rheumatoid arthritis (RA) activity, individuals with advanced RA are more likely to develop periodontal problems compared to their non-RA counterparts, and vice versa. Studies have been suggested that RA manifest as a result of an inflammatory imbalance and autoimmunity. In this perspective, treatment modalities that lead to inhibition of proinflammatory mediators, may prove beneficial for reducing the severity of RA. This study examined the effects of non surgical periodontal therapy (NSPT) on disease activity of RA. Methods: Diagnosed patients of active rheumatoid arthritis with chronic periodontitis were recruited in this study and divided in to treatment and controls groups, both groups were similar in all demographics assessed. Treatment group (n = 20) and controls group (n = 20) underwent assessment for periodontal clinical parameters (plaque index, gingival index, probing pocket depth, clinical attachment level), Rheumatologic clinical (simplified disease activity index) and biochemical parameters(C-reactive protein, Rheumatoid factor, Anticyclic citrullinated protein) at baseline and 8 weeks. Serum levels of biochemical parameters were measured by enzyme-linked immunosorbent assay (ELISA). Results: The statistically significant (p < 0.001) reduction observed in mean values of PI, GI, PPD, CAL, SDAI in treatment group at 8weeks after NSPT as compare to control group. However serum level of ACCPA, CRP and RF did not show statistically significant (p > 0.05) changes from baseline to reassessment (8 weeks) in both groups. Conclusions: The improvement in RA disease activity may occurs after non surgical periodontal therapy.

Both nonabsorbable and absorbable barrier membranes were equally effective in treating grade II buccal furcation defects in lower molars when used in conjunction with G-Graft except with respect to horizontal bone fill in which absorbable barrier membrane showed better results.
