Study of quantitative sleeping electroencephalography (EEG) in bruxism cases

Abstract

Bruxism is a behavioral disorder characterized by daytime or nighttime tooth grinding. Many etiological factors have been suggested for sleep bruxism. Among these, elevated mental and physical alertness have been proposed to characterize subjects with this disorder. This study aims to explore whether there is any relationship between bruxism and the sleep periods and sleep-state EEG data of the patients with bruxism. Twelve individuals with sleep bruxism (7 female and 5 male) and 8 normal individuals (5 female and 3 male) of a similar age group were monitored to this end. EEG records of all subjects were obtained. K-complex amplitude values were 96.08 ± 0.46 ?V for the subjects with bruxism and 126.00 ± 0.42 ?V for the control group. These values were statistically significant (P < 0.05). © Universitätsverlag Ulm GmbH 2005.
