Temporomandibular joint morphology in two Australian aboriginal populations
L. C. Richards
The morphology of the temporomandibular joints in two Australian
populations with previously established differences in patterns of tooth
wear and craniofacial morphology did not differ significantly from that
described in other comparable populations. The relationships between age
and linear and angular measures of joint form were generally not
significant, but the shape of the mandibular condyle was age-related, with
flattening and cavitation of the posterior and medial aspects being more
common in older age groups. Comparison of tooth-wear data in groups with
different mandibular condylar shapes suggested that rapid anterior tooth
wear was associated with flattening or cavitation of the condyle, while
relatively rapid posterior tooth wear was more commonly associated with a
convex condylar shape.
