Temporomandibular joint dysfunction syndrome and myofascial pain dysfunction syndrome: a critical review

Abstract

Temporomandibular joint (TMJ) dysfunction syndrome and myofascial pain dysfunction (MPD) syndrome have been primarily viewed as dental problems and have only recently received close attention by psychologists. The literature reviewed in the present paper reveals that a substantial portion of the population is affected by these disorders. There is, however, a great deal of confusion that exists in relation to the aetiology and treatment of these syndromes. In an attempt to clarify the current understanding of these disorders, the present review first presents a discussion of the symptoms which comprise each of these syndromes and the proposed physiological mechanisms associated with each symptom. Next, the aetiological theories for each of these syndromes are reviewed and critically evaluated. Treatments which have been derived from the theoretical models are then discussed. Finally, methodological considerations involving classification, assessment and treatment issues are presented and future research needs are outlined.

Dores dentárias de origem muscular em indivíduos com distúrbios crâniomandibulares e controles: estudo comparativo

“…O aumento de tensão, de fadiga e de dores musculares, que pode contribuir para o aparecimento de pontos desencadeantes e dores referidas, pode ter origem psicofisiológica. Corroborando esse ponto de vista, um estudo 1 reforça a opinião atual de que DCM tem etiologia multifatorial, de que a maioria dos problemas de dor crônica é considerada de natureza musculoesquelética e de que vários estudos consideraram o impacto do estresse em DCM e principalmente na dor e na sensibilidade dos músculos masticatórios 17 . Uma causa iatrogênica comum de SDDM ocorre quando os pacientes mantêm a boca aberta por longos períodos após procedimentos dentários 12 .…”

Effectiveness of acupuncture for temporomandibular disorders and associated symptoms

“…From 15 to 30 years of age, most frequent causes are of muscle origin and, as from 40 years of age of joint origin. Females are more affected than males, in a proportion of five females for each male [4][5][6][7][8][9] . Approximately 3.6 to 7% of the population have sufficiently severe TMD to look for medical assistence 1 .…”

Patient’s satisfaction and muscles activity after management of temporomandibular disorders patients using computer-aided design/computer-aided manufacturing versus conventional occlusal splints (randomized clinical trial)

“…[5] Conventional occlusal appliances are commonly used in the treatment of patients with TMD and have been reported to improve signs and symptoms in these patients. [6,7] Conventional methods of splint manufacture are highly technique sensitive and often lead to poor splint fit, over contour, and hence poor patient compliance. They also require extensive chair-side time for adjustments to achieve passive fit and an appropriate occlusal scheme.…”
