Comparison of the multiphasic dysfunction profile with lateral transcranial radiographs

Lateral transcranial radiographs of 926 patients were analyzed for condylar position, TMJ space, and obvious condylar morphologic changes. Differences in condylar position and joint space variations were noted between men and women. An increase in nonconcentric condylar position, joint space variations, and condylar morphologic changes were found with advancing age. There was a significant correlation of condylar position, joint space variations, and condylar morphology with mandibular dysfunction profile scores. Mandibular dysfunction is manifested by a wide range of signs and symptoms, none of which is always present with the disorder. Although TRs are limited in their total diagnostic value, their use in discerning major TMJ changes serves as an important adjunct in the examination and diagnosis of mandibular dysfunction.
