Objective: To correlate the clinical RDC/TMD findings with Magnetic resonance imaging (MRI) as a diagnostic aid in the internal derangement of TMJ. Methods: The present study consists of a total sample size of 14 subjects clinically diagnosed with the internal derangement of TMJ. According to the set criteria by Research Diagnostic Criteria for Temporomandibular disorders (RDC/TMD), the subjects were subjected to MRI after a thorough evaluation. The diagnostic findings were compared with MRI. The data obtained were statistically analyzed using the specificity, sensitivity, and kappa coefficient. Results: Twenty-five percent of sensitivity and fifty-seven percent of specificity were observed for RDC/TMD diagnosis regarding MRI in the total sample. Kappa value was found to be in the moderate range. Conclusion: The clinical findings based on RDC/TMD alone were not sufficient for the diagnosis of TMJ, and MRI’s internal derangement still a “golden standard” among the other modalities.
