Bruxism is a parafunctional habit of stomatognathic system characterized by the act of grinding or clenching the teeth, which can occur during sleep, called night bruxism. It is more common in children, uncommon in adults and reduced occurrence in the elderly. Have a multifactorial etiology and the International Classification of Sleep Disorders, associate bruxism with parasomnias, and characterized him by varying degrees of excitement, like bedwetting, speech during sleep, restless sleep and sleepwalking. During the primary dentition, bruxism is presented as a physiological feature associated with the development of facial bones, however from the moment it emerges mixed dentition, the transition to permanent dentition, this phenomenon should start to become less evident. When the night bruxism persists in it can be considered pathological, creating severe damage that can even lead to temporomandibular joint disorders. Night bruxism in children may have repercussions, particularly in the form of tooth wear, daytime wear physical and behavioral changes, so it is extremely important to early detection of bruxism in children by physicians. To remove the parafunctional habit is require multidisciplinary treatment. The visit of a child in to the University Clinic raised the question of existence of night bruxism in children with mixed dentition associated with parasomnias. This thesis aims to draw attention to the importance of early detection of bruxism as parasomnia. Was used a questionnaire conducted among parents about the nocturnal behaviors of children and assessed the extent to which bruxism is present in children with mixed dentition.
