Follow-up study of condylar bony changes using helical computed tomography in patients with temporomandibular disorder

In this study, the main direction of transition of condylar bone change in joints with TMD was absorptive bone change to absorptive with sclerotic (proliferative) bone change and further to sclerotic (proliferative) bone change. Our classification of condylar bone change was thought to be convenient for the evaluation of bone change in TMD.
