Aim and objective: The aim of the study is to compare clinical and magnetic resonance imaging diagnosis of the temporomandibular joint internal derangement, and to assess various other magnetic resonance imaging changes associated with internal derangement. Methods: The study group consists of 30 temporomandibular joints in 15 patients out of which 11 were females and 4 were males. These patients were within the age groups of 20 to 40 years with a mean age of 30.5 years. Result: The kappa statistical analysis for comparison of clinical and magnetic resonance imaging diagnosis of internal derangement was Κ = 0.80 which reveals substantial agreement and was statistically significant. Thus, the study shows that the clinical diagnosis of temporomandibular joint internal derangement correlated well with the magnetic resonance imaging diagnosis. Conclusion: This present study concludes that the diagnosis of temporomandibular joint internal derangement can be reliably made with appropriate patient history and clinical examination. Even though magnetic resonance imaging play a significant role in the diagnosis. Keywords: Temporomandibular joint, Internal derangement, Magnetic resonance imaging, Articular disk
