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
Bruxism there is only one randomized control trial which has reported that Botox reduces the myofascial pain symptoms. This scientific study was based on thirty people with bruxism who received Botox injections into the muscles of mastication and a control group of people with bruxism who received placebo injections. Normally multiple trials with larger cohorts are required to make any firm statement about the efficacy of a treatment. In 2013, a further randomized control trial investigating Botox in bruxism started. There is also little information available about the safety and long term followup of this treatment for bruxism.
