Abstract
|
|
|
The articular discs from temporomandibular joints of thirty men and women whose ages ranged between 20 and 70 years have been used in this study.
The articular discs of the temporomandibular joints of human postmortem material was examined individually by means of microscopic techniques.
The following changes were seen:
1. With advancing age some of fibroblast was developed into chondroid cells. Which later may differentiate into true chondrocytes.
2. In young individuals the elastic fibers found only in relatively small numbers. With advancing age elastic fibers was increased in number.
3. With advancing age the arrangement of fibrous tissue are irregular and loosely separated.
4. In the discs, as well as in the fibrous tissue covering the articular surfaces, this cellular changes seems to be dependent upon mechanical influences.
