Risk factors for sleep bruxism

Although the pathophysiology of sleep bruxism (SB) is unknown, it is considered a multifactorial disorder characterized by the rhythmic activation of masticatory muscles that results in grinding and/or clenching of the teeth and bracing and/or thrusting of the mandible during sleep. It is believed to be centrally mediated. Its effect on quality of life is related to the dental and orofacial problems it creates, which result in tooth wear, masticatory muscle tenderness and pain, headache, and temporomandibular disorders (TMDs).
