Occlusion as it relates to TMJ. A study of the literature

References in this report are to papers that basically point toward similar findings. They have helped in the search for the etiology of TMJ dysfunction. We have tried to point out that there is no research that shows that restorative dentistry or orthodontics are etiological factors in TMJ dysfunction. The old bug-a-boo about what causes TMJ--why it is more prevalent in women, etc.--is still under intensive study. Again, we should use a cautious approach to TMJ, be positive, be informed, and proceed with the right method, that is, a valid diagnosis before treatment.
