Tissue reactions associated with internal derangement of the temporomandibular joint: A radiographic, cryomorphologic, and histologic study

The prevalence of osteoarthrosis in cases of advanced internal derangement of the Temporomandibular Joint: a clinical, surgical and histological study

“…Early studies undertaken in the 1980s showed inflammatory cell infiltrates were not a prominent feature of painful TMJ internal derangement 8,[10][11][12] , whereas the present study demonstrated inflammatory cells in just over half the joints (54%). Later studies 7,9 , however, found inflammation in about two-thirds of the joints studied which was greater than the 54% of joints (12/22) found with inflammation in the present study ( Table 3).…”

“…Hyalinization is often considered part of the aging process where there is a marked decrease in cells and vessels that are replaced by a significant abundance of collagen 19 . When the collagen fibres have a crushed appearance it is more likely to be disease rather than age related, as found in previous studies that looked at long-standing TMJ pain 10,11 . In this study, the presence of hyalinization, particularly in the younger patients was indicative of abnormal degenerative changes in the articular disk as most specimens demonstrated a crushed appearance of the collagen fibres.…”

“…The TMJ articular disk and synovial lining have been the subject of several histological studies that have focused on the diseased state without adequate reference to closely matched control specimens from non-diseased joints 1,[9][10][11] . In fact, most attempts to include control specimens have relied on autopsy material obtained from older individuals with an unknown clinical TMJ profile 13,17,18 .…”

A Potential Reference Point for Assessment of Condylar Bone Marrow of the Temporomandibular Joint On Proton Density Weighted Images

“…here are several possible sources of temporomandibular joint (TMJ) pain, including alterations in the bone marrow of the mandibular condyle, osteoarthritis, [1][2][3][4][5] impingement and compression of the retrodiscal tissue, 6,7 inflammatory changes in the retrodiscal tissue, 8,9 inflammatory changes in the joint space resulting in joint effusion 10 and capsulitis. [11][12][13] Osteoarthritis is suggested as a source of pain, but is also often seen in asymptomatic subjects.…”

Avaliação global da postura ortostática de indivíduos portadores de distúrbios internos da articulação temporomandibular : aplicabilidade de métodos clínicos, fotográficos e radiográficos

“…A sonografia registra ruídos articulares produzidos somente durante movimentos de abertura e fechamento mandibular, ao passo que a axiografia registra ruídos produzidos em qualquer movimentação espacial da mandíbula. BRACCO et al (1997) (GROSS & GALE, 1983;YEMM, 1985;ASH, 1986), ou se eles são um sinal significativo de distúrbio interno da articulação (FARRAR & MCCARTY, 1979;ISBERG & ISACSSON, 1986). Propõe -se também que o clique da ATM seja um distúrbio progressivo (DOLWICK, 1983 …”
