Topical review: sleep bruxism and the role of peripheral sensory influences.

摘要: Sleep bruxism (SB) is an unusual orofacial movement described as a parafunction in dentistry and parasomnia sleep medicine. Since several peripheral influences could be involved sleep-wake regulation the genesis of rhythmic jaw movements, authors have reviewed relevant literature to facilitate understanding mechanisms possibly SB genesis. Various animal human studies indicate that during either wakefulness or anesthesia, sensory inputs (eg, from periodontium, mucosa, muscle) influence muscle activity. However, role these motor activity unclear. Interestingly, sleep, usually open due suppression; tooth contact most likely occurs association with arousal. Recent physiologic evidence supports between arousal SB; sequential change autonomic (cardiac) brain cortical activities precede SB-related This suggests central and/or nervous systems, rather than factors, dominant some factors may exert on through their interaction mechanisms. The intent this review integrate various concepts order better understand underlying SB.
