With the advent of magnetic resonance imaging, or MRI, clinicians and researchers have sophisticated techniques by which to assess the anatomy of the temporomandibular joint, or TMJ. Imaging is indicated when the results will affect the patient's care beyond that which can be gained from a complete clinical assessment. One of the primary indications for treatment of patients with temporomandibular disorders, or TMDs, is jaw pain, including TMJ pain. Therefore, it is necessary to assess whether MRI-depicted TMJ findings are associated with TMJ pain. This study assessed the relationship between TMJ pain and clinical and MRI findings. ⋯ The results of this study suggest that palpation of the TMJ is superior to MRI in identifying the joint as the source of pain. Therefore, the most cost-effective and valid test to determine if the TMJ is a source of jaw pain is a complete clinical assessment.
