Sleep Bruxism (BS) is defined as a stereotyped movement disorder that occurs during sleep, characterized by grinding and / or clenching tooth. It lies within the international classification of sleep disorders as a movement disorder associated with an exaggerated rhythmic masticatory muscle activity. We report an incidence of 15% to 22% in the general population. Formerly it was believed that the etiology of BS was related to occlusal alterations, but it is now thought that the main cause is more related to sleep disorders, central nervous system diseases, drugs, chronic pain, emotional distress, among other factors participate in origin. It has identified the presence of various systemic pathophysiological phenomena that occur during an episode of BS, among which are the arousal, changes in heart rate, sympathetic tone, blood pressure, among others, on which is this review.
