This pilot investigation was concerned with the study of bruxing patterns during sleep of five young subjects each representing a dental treatment category showing a distinct level of tooth wear. Electroencephalogram (EEG), electrooculogram (EOG), and electromyogram (EMG) activity was recorded on two consecutive nights. All five sleep profiles were very similar to the established norms for their age group. It was observed that EMG disturbances which may be associated with bruxing occurred in all sleep stages but predominantly in Stage 2 and rapid eye movement (REM) sleep. There were no systematic differences in EMG disturbances related to different levels of dental treatment and tooth wear.
