Degenerative changes in the temporomandibular joint in two Australian aboriginal populations
1Department of Dentistry, University of Adelaide, Australia.
Abstract:
The frequency and severity of degenerative changes in the temporomandibular joints in two Australian Aboriginal populations with different patterns of tooth wear, craniofacial morphology, and temporomandibular joint morphology were examined. The incidence of degenerative changes differed between groups and between sexes and increased with age, ranging from zero in the youngest groups to 65% in the oldest, most severely affected group. Degenerative changes of the fossa were more frequent than condylar changes. Significant associations between degenerative changes and both the pattern of tooth wear and aspects of facial morphology were also evident.

Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...
