Abstract: Periodontitis is an immunoinflammatory disease with multifactorial involvement caused by plaque microorganisms. Rheumatoid arthritis is a systemic immune disease characterized by chronic inflammation and destroy in joint tissues. Both diseases share similarities in pathological processes and mechanisms of tissue destruction, including bone destruction, soft tissue inflammation, and the influence of the same environmental factors etc. In recent years, increasing attention has been put on the role of gut microbiota dysbiosis in systemic diseases, where periodontal pathogenic bacteria may enter the intestine through swallowing to affect gut microecology. Dysbiosis of gut microbiota can further aggravate the development of arthritis. The purpose of this review is to reveal the possible effects of gut microbiota on interactions between periodontitis and rheumatoid arthritis through the gut microbiota, as well as the related mechanism. Hopefully, this review will identify new insights on the relationship between periodontitis and rheumatoid arthritis.

Key words: periodontitis, rheumatoid arthritis, gut microbiota
