Abstract:
Researches in pathologic entities and syndromes that describe temporomandibular joint (TMJ) or TMJ-related pain and dysfunction, have been hampered by confusion and conflict over the pathogenesis of myofascial and joint pain, the character and causes of joint noises, and the lack of scientific methods. Investigators have more recently correlated clinical diagnosis and arthrographic and surgical findings to demonstrate "internal derangements" of the TMJ. It is thought that the structural and functional changes characteristic of internal derangements constitute the principal pathologic entity of the TMJ. Cephalometric data from a group of 34 subjects with documented functional changes in the TMJ were compared with those of a group of 35 subjects from a control sample. The results were as follows: 1. Comparison of a group which shows Class I relationship, there was a tendency to show clockwise rotation of mandible and linguoversion of upper and lower anterior teeth in the experimental sample. 2. Excluding the vertical relationship, there was a tendency to show low values of the lingual surface slope of the upper central incisor and high values of the interincisor angle in the experimental sample.
