Effects of tofacitinib on the clinical features of periodontitis in patients with rheumatoid arthritis: two case reports

Background The pathobiology of rheumatoid arthritis (RA) is similar to that of periodontitis in that proinflammatory cytokines play an important pathologic role. There is evidence to suggest that inhibitors of tumor necrosis factor (TNF) and interleukin-6 (IL-6) receptor for the treatment of RA ameliorated periodontal inflammation. However, no study has evaluated the effect of tofacitinib, an oral Janus kinase inhibitor for the treatment of RA, on periodontitis.
