Comparison of skeletal and dental morphology in asymptomatic volunteers and symptomatic patients with normal temporomandibular joints.

The purpose of this study was to evaluate the skeletal and dental pattern of symptomatic individuals (SN) with normal temporomandibular joints (TMJs). There were 42 symptomatic female patients with bilaterally normal TMJs and 46 asymptomatic normal female volunteers (AV). All study participants had bilateral high-resolution magnetic resonance scans in the sagittal (closed and open) and coronal (closed) planes to evaluate the TMJs. Linear and angular cephalometric measurements were taken to evaluate the skeletal, denture base, and dental characteristics of the two groups. ANOVA was used to compare the symptomatic subjects with the control subjects. There were no significant differences between the two groups besides the lower incisor being more retruded in the asymptomatic group. This study showed that there are no alterations in skeletal morphology in SN individuals compared with AV.
