Abstract
Objective: The aim of the study was to evaluate the value of MRI imaging in internal derangement of the temporoman-dibular joint (TMJ) in patients with TMJ disorders symptoms (TMJDs).
Methods: The study included 42 patients (84 joint) pre-sented with TMJDs (34 females and 8 males). Their age ranged from 27 to 52 years with mean age of (40.3 years). MRI was done to all patients and was assessed.
Results: The disc was abnormal in (66.7%), classified into ADDR (anterior disc displacement with reduction), found in (60.7%), ADDWR (anterior disc displacement without reduction) found in (2.4%), ADDR+E (anterior disc displace-ment with reduction + effusion) found in (1.2%), ADDWR + E (anterior disc displacement without reduction + effusion) found in (2.4%).
Conclusion: MRI is non invasive valuable modality with promising diagnostic ability in diagnosis of TMJDs. High association was found between TMJDs and patients with depressive disorders. Strong association was found between abnormal disc position and joint pain and noise.
