Nocturnal bruxism and temporomandibular disorders.
This chapter has discussed the important aspects of nocturnal bruxism and its relation to disorders of the masticatory system and headaches. Bruxism is believed to be a stress-related sleep disorder, occurring in both men and women, in children, and in adults. In most patients, bruxism results only in minor tooth wear; however, it can become extremely severe with damage occurring in essentially every part of the masticatory apparatus. Nocturnal bruxism should not be overlooked as an etiologic factor in muscular headaches. Short-term acute therapy may involve physical therapy, nocturnal electromyographic biofeedback, and medication to relieve anxiety and improve sleep. Long-term management usually includes some form of stress reduction, change in lifestyle, and an occlusal splint or nightguard to protect the teeth and masticatory system.
