Temporomandibular joint (TMJ) is one of the most important, unique and structurally has the highest complex synovial system in the body (1, 2). TMJ, encompassing the temporal bone, mandibular condyle and articular disc, is a diarthrodial joint. As a collective form, Temporomandibular Joint Disorders (TMD) is often with multifactorial etiologies, and these diseases can more commonly affect the soft-tissue components of the TMJ including the articular disc and posterior attachment, the osseous components of the TMJ and also the related muscles (3, 4). The most common cause of the regional orofacial pain of non-dental origin is a result of TMD. Additional symptoms may include TMJ sounds such as clicking, pumping, limited or asymmetric mandibular movement (5). As TMJ is covered by a layer of fibrocartilage, unlike other joints in the human body, the mandibular condyles can be damaged due to cartilage degeneration. In addition, arthritis can also be initiated because of the particular dynamics in the maxillofacial area (6). TMD's are frequently associated with degenerative bone changes which can involve the bone structures of the TMJ such as erosion, flattening, osteophytes, subchondral bone sclerosis and pseudocysts (7). To correctly diagnose the dysfunctions associated with the disease and for adequate treatment planning Knowledge about these bone changes is fundamental (8).
