MRI has the problem of artefacts caused by metal or body motion and is also incompatible for patients with claustrophobia. Arthrography is invasive and involves the risk of perforation or allergy to a contrast medium. This report discusses a patient with temporomandibular joint (TMJ) disorder who required soft tissue imaging of the TMJ. As she had claustrophobia and a reaction to iodine, air contrast arthrography and pumping manipulation therapy using limited cone beam computed tomography for dental use (3DX) was performed. We conclude that the 3DX examination method used in the study is practical as a diagnostic procedure and thus recommend this method to be used for patients with TMJ disorder in the presence of iodine contraindication.
