Variation of condylar asymmetry with age in edentulous patients with a craniomandibular disorder of myogenous origin

Abstract

The effect of age on condylar asymmetry in dentate patients has already been investigated and a clear relationship between these two variables was established both for a group with an arthrogenous origin and with myogenous origin of pain. In this study, the mean asymmetry index for an edentulous group of patients with a craniomandibular disorder of myogenous origin was found to be 12.55%, less than that for both dentate groups. There appeared to be no correlation between age and the asymmetry index in this group, suggesting that different mechanisms may be at work in the development of these disorders.
