===Degenerative joint disease===
The general term "degenerative joint disease" refers to arthritis (both [[osteoarthritis]] and [[rheumatoid arthritis]]) and arthrosis. The term arthrosis may cause confusion since in the specialized TMD literature it means something slightly different from in the wider medical literature. In medicine generally, arthrosis can be a nonspecific term for a joint, any disease of a joint (or specifically degenerative joint disease), and is also used as a synonym for osteoarthritis.<ref>{{cite web|title=Definitions of "Arthrosis" from various medical and popular dictionaries |url=http://medical-dictionary.thefreedictionary.com/arthrosis|publisher=Farlex |access-date=30 May 2013}}</ref> In the specialized literature that has evolved around TMD research, arthrosis is differentiated from arthritis by the presence of low and no inflammation respectively.<ref name="Cairns 2010" /> Both are however equally degenerative.<ref name="Cairns 2010" /> The TMJs are sometimes described as one of the most used joints in the body. Over time, either with normal use or with parafunctional use of the joint, wear and degeneration can occur, termed osteoarthritis. Rheumatoid arthritis, an [[autoimmune]] joint disease, can also affect the TMJs. Degenerative joint diseases may lead to defects in the shape of the tissues of the joint, limitation of function (e.g. restricted mandibular movements), and joint pain.<ref name="Cairns 2010" />
