Outcomes of Periodontal therapy in Rheumatoid Arthritis: the OPERA feasibility randomised trial.

Overall, the trial was feasible and acceptable to study participants.

In this feasibility study of patients with RA and periodontitis, periodontal treatment resulted in significant improvements in periodontal disease outcomes and overall RA disease activity, although complete resolution of periodontal inflammation was difficult to achieve in some cases.
