Abstract
Regarding the mechanism of temporomandibular disorders (TMDs), TMD pain including muscle tenderness to palpation is considered to be caused by masticatory muscle fatigue induced with occlusal discrepancy. Temporomandibualr joint (TMJ) derangement is considered to be occurred due to mandibular displacement from muscular position to habitual position.
