Sleep bruxism has previously been viewed as a dysfunctional movement or pathological condition, whereas it is now accepted as a centrally controlled condition with various systemic risk factors. It has been postulated that sleep bruxism may have a protective role during sleep, for example in relation to airway maintenance or in stimulating saliva flow. A diagnosis of sleep bruxism may be made via patient report and clinical interview, clinical examination, intraoral appliances or recording of muscle activity. Bruxism in itself does not require treatment: management is only indicated where problems arise as a result of bruxism. Oral appliances primarily aim to protect the dentition from damage caused by clenching/grinding, although they may reduce muscle activity. Irreversible occlusal adjustments have no basis in evidence in the management of bruxism. Behavioural strategies include biofeedback, relaxation and improvement of slee...Continue Reading
