OBJECTIVES: @entity1348 ( @entity1348 ) dysfunction is a common condition that is best evaluated with magnetic resonance (MR) imaging. The first step in MR imaging of the @entity1348 is to evaluate the articular disk, or meniscus, in terms of its morphologic features and its location relative to the condyle in both closed- and @entity2133 . Disk location is of prime importance because the presence of a displaced disk is a critical sign of @entity1348 . However, disk displacement is also frequently seen in asymptomatic volunteers. It is important for the maxillofacial radiologist to detect early MR imaging signs of dysfunction, thereby avoiding the evolution of this condition to its advanced and irreversible phase which is characterized by osteoarthritic changes such as condylar flattening or @entity5040 . Further the MR imaging techniques will allow a better understanding of the sources of @entity158 and of any discrepancy between imaging findings and @entity1 symptoms. Henceforth, the aim of the study was to evaluate whether MRI findings of various degrees of disk displacement could be correlated with the presence or absence of clinical signs and symptoms of @entity2956 in symptomatic and asymptomatic subjects. Materials and Methods : In this clinical study, 44 @entity1 (88 TMJs) were examined clinically and divided into two groups. Group 1 consisted of 22 @entity1 with clinical signs and symptoms of TMDs either unilaterally or bilaterally and considered as study group. Group 2 consisted of 22 @entity1 with no signs and symptoms of TMDs and considered as control group. MRI was done for both the TMJs of each @entity1 . Displacement of the posterior band of articular disc in relation to the condyle was quantified as anterior disc displacement with reduction (ADDR), anterior disc displacement without reduction (ADDWR), @entity890 ( @entity890 ). Results : Disk displacement was found in 18 (81.8%) @entity1 of 22 symptomatic subjects in Group 1 on MRI and 4 (18.1%) were diagnosed normal with no disc displacement. In Group 2, 2 (9.1%) of 22 asymptomatic @entity1 were diagnosed with disc displacement while 20 (90.1%) were normal. Sensitivity and Specificity tests were applied in both the groups to correlate clinical findings of @entity9321 and MRI characterstics of disc displacement and results showed Sensitivity of 90% and Specificity of 83.3%. Conclusion : Disk displacement on MRI correlated well with presence or absence of clinical signs and symptoms of @entity2956 with high Sensitivity and Specificity of 90% and 83.3% respectively.
