Autoimmune diseases, such as rheumatoid arthritis (RA), are examples of yet not entirely understood etiology.

The progression of both chronic periodontitis and RA is linked to the dysregulation of the immune system and the damage caused by the immune response. Previous detailed studies have indicated that a specific enzyme of P. gingivalis, peptidyl-arginine deiminase, which catalyzes the citrullination of proteins, may trigger the autoimmune response resulting in the development of RA.
