A Study of Temporomandibular Joint Sounds; Part 1. Relationship with Afficular 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 … Show more

“…23 Some studies associated joint hypermobility to TMJ symptoms 24,25 and clicking to ligament alteration. 11,26 Nevertheless, not only ligaments are important to articular stability but muscles too. 14 Therefore, the highest vibratory energy at the end of the opening and beginning of the closing cycles in our patients may be related to articular laxity.…”

“…Estudos epidemiológicos mostram que os sons articulares estão presentes em 34 a 65% da população em geral (GROSS;GALE, 1983;GAY;BERTOLAMI, 1988). A ausência de sons articulares não exclui a possibilidade da DTM e tem sido observado nos casos de deslocamento do disco sem redução e em articulações com extensas áreas de remodelamento articular (ERIKSSON et al, 1985), sugerindo que muitos pacientes não têm sons articulares na presença de deslocamento do disco, o que implica uma alta prevalência falso-negativa do exame clínico (MOTOYOSHI et al, 1994;PURI et al, 2006).…”

“…Entre as causas e alterações estruturais que podem causar algum tipo de som articular, as mais freqüentes são os deslocamentos de disco articular para anterior, alterações estruturais de superfície articular e hipermobilidade do complexo côndilo-disco, além dos processos degenerativos, que provocaram as crepitações 7,9,15,16,19,22,24 . O relacionamento entre os deslocamentos de disco articular e a sintomatologia dolorosa da ATM ainda não está bem elucidado.…”
