Objectives: The purpose of this review was tocompare ultrasonography with Magnetic Resonance Imaging (MRI) in the diagnosis of Internal Disk Derangement of Temporomandibular Joint(TMJ). Method: MEDLINE, The Cochrane Library, IndMed and Google Scholar were searched for studies for studies from 1st January 1991 to December 2016. Two reviewers independently screened the articles for eligibility criteria. Studies comparing MRI and Ultrasonography imaging for diagnosing temporomandibular joint disorder (internal disk derangement) were included. Only relevant studies that met the reviewer’s objectives were considered. Results: 7 articles out of 345 articles met the eligibility criteria which showed that the accuracy of ultrasonography ranged from 73.10% - 95%, sensitivity was found to be 65% to 90% and specificity was 72.70% to 100% as compared to MRI. Conclusions: Both MRI and ultrasonography can be used to diagnose internal disk derangement in TMJ. Further studies should be conducted to make ultrasonography more reliable as a diagnostic tool.
