Sleep-related bruxism on polysomnography

This figure shows a 30-second epoch of a PSG with prominent sleep-related bruxism (dashed box). The clear arousal sequence of sleep-related bruxism can be seen in the EEG leads of the PSG.

PSG: polysomnography; EEG: electroencephalography; EOG: electrooculography; EMG: electromyography; ECG: electrocardiography.
