Bruxism movements that occur with seizure disorders (e.g. epilepsy). This usually involves a dental examination, and possibly electroencephalography if a seizure disorder is suspected. Polysomnography shows increased masseter and temporalis muscular activity during sleep. Polysomnography may involve electroencephalography, electromyography, electrocardiography, air flow monitoring and audio–video recording. It may be useful to help exclude other sleep disorders; however, due to the expense of the use of a sleep lab, polysomnography is mostly of relevance to research rather than routine clinical diagnosis of bruxism. Tooth wear may be brought to the person's attention during routine dental examination. With awake bruxism, most people will

The decreolization theory for the emergence of habitual "be" in AAE is the most likely and most supported of the theories of its origin. It involves the decreolization process of Caribbean English creole, with the loss of "does (be)", which itself is a decreolization of a previous creole habitual marker and its
