[Effect of silence information regulator 3 on temporomandibular joint osteoarthritis].

Temporomandibular joint osteoarthritis (TMJOA) is a common subclass of temporomandibular disorders, with complicated causes and limited treatment. In addition to inflammatory reaction, structural changes of temporomandibular joint (TMJ) as condylar osteophyte formation, sclerosis, erosion, and subchondral bone cysts will happen at the same time. At present, it is found that epigenetic regulation can affect the growth and development of TMJ and regulate the immune inflammatory reaction, so we can speculate that epigenetic modification is involved in the occurrence and development of TMJOA. This paper reviews the researches of silence information regulator 3 (SIRT3), which is a key factor in epigenetics, in the field of osteoarthritis and rheumatoid arthritis.In order to discuss the effect of SIRT3 on the growth and development of TMJ by mediating acetylation modification, such as bone, cartilage, synovium and blood vessels, as well as alleviating osteoarthritis and synovitis. By doing this, the understanding of TMJOA can be enriched, with the goal of finding a new possibility for the clinical treatment of TMJOA.
