Abstract Objective To determine the association between unilateral temporomandibular joint disorder (TMD) and the presence of imaging abnormalities in the contralateral, asymptomatic joint. Methods MRI studies of 219 subjects with symptoms of unilateral TMD were examined for signs of disc displacement, osteoarthritis, disc deformation, and effusion in both temporomandibular joints (TMJ). The Chi-Square test and stepwise logistic regression analysis were performed. Results Disc displacement, osteoarthritis, disc deformation, and effusion were more common on the symptomatic side. However, in the category of disc displacement with a reduction in open mouth position (DDWR), the difference was not significant between the symptomatic and the asymptomatic TMJs. Stepwise logistic regression showed that the presence of any imaging abnormality other than DDWR was related to osteoarthritis and disc deformity on the symptomatic side. On the other hand, the presence of any MRI abnormality (including DDWR) on the asymptomatic side was related only to the presence of osteoarthritis on the symptomatic side. Conclusions Unilateral symptomatic TMD is related to the presence of imaging abnormalities on the contralateral, asymptomatic side, suggesting that the development and progression of joint changes in symptomatic and contralateral asymptomatic TMJs are interrelated.

Introduction The temporomandibular joint (TMJ) is a diarthrodial joint connected by the mandible. The two sides cannot, therefore, function independently. The two TMJs must work together to produce the movements necessary for speech, mastication, deglutition, and facial expression [1]. Mandibular mechanics during the opening, closing, and mastication are abnormal in the presence of symptomatic internal derangement (ID) [2]. Temporomandibular joint disorder (TMD) is a relatively common clinical condition, affecting up to 28% of the world population [3], with a prevalence of symptoms between 17% and 68.8% [4, 5]. Patients usually complain of pain, joint * C. Jerele [email protected] 1

clicking, and restricted mandibular movement, which have a significant effect on their quality of life [1]. Magnetic resonance imaging (MRI) has a central role in the evaluation of TMD. It is reported to have 95% accuracy for disc position and disc form and about 93% for osseous change [6]. However, some authors have r
