Sensory and motor integration during mandibular function.
The subject of pain is intimately related to that of mandibular function. It is now clear that certain types of temporomandibular disorders, particularly myofascial pain dysfunction, result, in part, from rhythmic muscle activity produced by parafunctional oral habits such as diurnal or nocturnal bruxism. Furthermore, in addition to phasic hyperactivity, evidence also suggests that masticatory muscles of patients with MPD are tonically hyperactive. The pain associated with such hyperactive musculature prompts many patients to seek professional help. This article provides an updated historical review of one important aspect of mandibular function and gives insight into the general "state of the art."
