Abstract

Aim: The purpose of this study is to investigate the relationship between TMJ disc displacement and chondylar degenerativechanges.Material and Methods: The MRIs of 182 TMJs belonging to 91 patients with TMD were evaluated. TMJs were distributed into threegroups according to the disc positions as normal disc position (Group 1, n=39), disc displacement with reduction (Group 2, n=49) anddisc displacement without reduction (Group 3, n=94). Condylar degenerative change is diagnosed according to presence or absenceof erosion, sclerosis, flattening and osteophyte encountered in MRI. When more than one type of degenerative change was observed,the joint was determined to have degenerative changes.Results: The results of MRI evaluation of 182 TMJs revealed Group 1, Group 2 and Group 3 in 39 (21.4%), 49 (26.9%) and 94(51.6%) joints, respectively. No degenerative condyle was found in 107 (58.8%) joints whereas degenerative condylar changes wereencountered in 75 (41.2%) of 182 TMJs by the MRI evaluation. Condyle degeneration was detected in 2 (5.1%) of the joints withnormal disc position whereas 6 (12.2%) and 67 (71.3%) of the joints with reducing and non-reducing disc displacement revealedcondyle degeneration, respectively.Conclusion: A statistically significantly higher rate of condyle degeneration was encountered in the joints with disc displacementwithout reduction than the joints with disc displacement with reduction and normal disc position. Advancing disc displacementcauses condylar degenerative changes.
