Background: There is a need to assess Temporo Mandibular Joint (TMJ) arthralgia and other symptoms like locking and clicking by non invasive methods like Magnetic Resonance Imaging(MRI). Methods: 100 TMJs were assessed on 1.5 T plain MRI in closed and open mouth positions. Images were obtained in the oblique coronal and oblique sagittal orientation to delineate the articular disc in the entirety. Results: Many significant relationships were obtained between the clinical manifestations of the internal derangements of the TMJ and the MRI findings of disc abnormalities and mandibular condylar pathologies like hypoplasia. TMJ syndrome was seen to affect the relatively younger patients and is a source of morbidity in the economically productive age groups. There is significant relationship between the pain and disc displacement with reduction (DDR). Disc displacement with reduction on mouth opening (DDR) is much commoner than disc displacement with no reduction (DDNR). Mandibular hypoplasia and pain have near significant relationship (p= 0.056). Further studies with larger sample sizes than our study, is recommended to test the association between the two. TMJ with clicking has significant association with disc displacement with reduction (DDR). Mandibular hypoplasia has significant relationship with disc displacement with no reduction (DDNR). This association has not been reported by previous studies, according to our knowledge. Cases with mandibular hypoplasia are more likely to develop secondary degenerative changes. This association was found to be near significant (p= 0.0525). Further studies with larger sample sizes than our study, is recommended to test the association between the two. Conclusion: MRI in closed and open mouth position to assess the TMJ disc and adjacent relevant structures around the TMJ remains the gold standard for the evaluation of this joint and should be the standard of care before offering the treatment for the same.
