title: A study of temporomandibular joint sounds; Part 1. Relationship with articular disc displacements.
abstract: The relationship between complaints about temporomandibular joint (TMJ) sounds and the prevalence of disc displacements was studied. The rate of incidence of TMJ sounds was 42% in the 50 subjects investigated. In the subjects with TMJ sounds, 19% were diagnosed as having articular disc displacements. In the 58% sound-free subjects, 14% were found to have disc displacements. Therefore, it seems that patients with TMJ sounds do not always have disc displacements, and that a sound-free state does not necessarily indicate a healthy TMJ.
