Abstract

Background:Magnetic resonance imaging (MRI) is indicated when a patient is diagnosed with temporomandibular joint (TMJ) disorders to assess internal derangement. Therefore, it is required to evaluate whether MRI findings of the TMJ are associated with TMJ pain. Aims/Objectives:This study aims to evaluate and compare the MRI findings in patients suffering from TMJ dysfunction and asymptomatic volunteers. Material and Methods:This study included age and gender matched 20 patients among which 10 were diagnosed with symptoms of TMJ dysfunction (test group) and 10 were asymptomatic patients (control group). MRI imaging in open- and closed-mouth positions was acquired and interpreted by a radiologist, and the results were statistically analyzed. Results:Anterior medial disc displacement was seen in 10%, and thinning of the posterior band was seen in 10% in asymptomatic volunteers. Displacement of disc with and without reduction was noted in 20% and intrasubstance degenerative changes were seen in 10% of symptomatic patients. Conclusions:The MRI results for TMJ dysfunction might not be easily understood, indicating that clinical assessment remains crucial. While MRI is not the only factor in defining TMJ dysfunction, it does seem necessary to support the clinical findings.
