Electromyographic analysis of bruxism in a patient with Rett syndrome

Rett syndrome (RTT) was neurological disorder which affects usually female. They have severe autism, loss of purposeful use hand, weight loss and epilepsy. Previous dental reports suggested that RTT patient frequently have bruxism, and they recommended biteplate therapy for tooth protection from bruxism. However, we did not find any physiological approach of bruxism in patient with RTT. Here we first report of bruxism status of RTT by using EMG analysis, biteplate therapy, and make evidence of it. The masseter muscle EMG activity was statistically significant reduced after template therapy. This data was scientifically evidence that template therapy was useful tool for protect form tooth wear caused bruxism with RTT patient.
