Rheumatoid arthritis (RA) is an immune-mediated inflammatory disease (IMID), chronic progressive causing inflammation in the joints and resulting in painful deformity and immobility, especially in the fingers, wrists, feet, and ankles. Periodontitis is defined as an inflammatory disease of supporting tissues of teeth caused by specific microorganisms or their groups, resulting in progressive destruction of the periodontal ligament and alveolar bone with periodontal pocket formation, clinical attachment loss, or both. Individuals manifesting both periodontitis and RA may suffer from a unifying underlying systemic dysregulation of the inflammatory response. In the past few years, increasing attention has been given to aspects of oral health in patients with rheumatoid arthritis, especially related to associations with periodontal disease. In this chapter we will be reviewing about the pathophysiology of RA and role of inflammation, periodontal disease: a gateway to RA, oral manifestations of RA, immunogenetics of RA and periodontitis, treatment implications for RA and periodontitis based on common pathophysiology.
