It has been demonstrated that osteoarthrotic changes in the temporomandibular joint (TMJ) and in other synovial joints show a similar course, both clinically and (ultra)microscopically. Initially, cartilage changes and possibly also changes in the synovial membrane set up a vicious cycle of cartilage breakdown accompanied by attempts at repair. When the degradative process exceeds the response of repair, the osteoarthrotic disorder progresses into clinically detectable stages. Frequently, the gliding capacity of the articular disc is also impaired, giving rise to an internal derangement. In this article, a concept is presented in which it is suggested that in many cases of craniomandibular pain and dysfunction TMJ osteoarthrosis is the basic disorder.

UI MeSH Term Description Entries
D010003 Osteoarthritis A progressive, degenerative joint disease, the most common form of arthritis, especially in older persons. The disease is thought to result not from the aging process but from biochemical changes and biomechanical stresses affecting articular cartilage. In the foreign literature it is often called osteoarthrosis deformans.

D001732 Bite Force The force applied by the masticatory muscles in dental occlusion. Masticatory Force,Occlusal Force,Bite Forces,Force, Bite,Force, Masticatory,Force, Occlusal,Forces, Bite,Forces, Masticatory,Forces, Occlusal,Masticatory Forces,Occlusal Forces
D002358 Cartilage, Articular A protective layer of firm, flexible cartilage over the articulating ends of bones. It provides a smooth surface for joint movement, protecting the ends of long bones from wear at points of contact. Articular Cartilage,Articular Cartilages,Cartilages, Articular
D004204 Joint Dislocations Displacement of bones from their normal positions at a joint. Inferior Dislocation,Joint Subluxations,Luxatio Erecta,Dislocation, Joint,Dislocations, Joint,Inferior Dislocations,Joint Dislocation,Joint Subluxation,Subluxation, Joint,Subluxations, Joint
D005157 Facial Pain Pain in the facial region including orofacial pain and craniofacial pain. Associated conditions include local inflammatory and neoplastic disorders and neuralgic syndromes involving the trigeminal, facial, and glossopharyngeal nerves. Conditions which feature recurrent or persistent facial pain as the primary manifestation of disease are referred to as FACIAL PAIN SYNDROMES.

D013582 Synovial Fluid The clear, viscous fluid secreted by the SYNOVIAL MEMBRANE. It contains mucin, albumin, fat, and mineral salts and serves to lubricate joints. Synovia,Fluid, Synovial,Fluids, Synovial,Synovial Fluids
D013705 Temporomandibular Joint Disorders A variety of conditions affecting the anatomic and functional characteristics of the temporomandibular joint. Factors contributing to the complexity of temporomandibular diseases are its relation to dentition and mastication and the symptomatic effects in other areas which account for referred pain to the joint and the difficulties in applying traditional diagnostic procedures to temporomandibular joint pathology where tissue is rarely obtained and x-rays are often inadequate or nonspecific. Common diseases are developmental abnormalities, trauma, subluxation, luxation, arthritis, and neoplasia.
