OBJECTIVE:To evaluate the role of CT in the diagnosis of temporomandibular joint dysfunction MATERIAL: 48 temporomandibular joints of 26 patients suspecting osseous changes were examined by CT, with 1mm of layer thickness. All patients had Sch llers position projection as comparison. RESULTS:CT is more sensitive to detect the osseous changes of TMJ than Sch llers position projection, but not well demonstrating sclerosis of TMJ. The Sch llers position projection can only shows the lesion of lateral 1/3 of condyle, but CT including total condyle. CONCLUSION: CT is an important and sensitive tool in detecting osseous changes of temporomandibular joint.
