Abstract:
Objective To analyze the sleep electrophysiological changes and the sleep structure changes in children with bruxism by use of the polysomnography. Methods Twelve children with severe bruxism and 11 children who had no systemic diseases or sleep disorders were selected for polysomnography.Results The proportion of nonrapid eye movements sleep(NREMS) Ⅱ and NREMS Ⅳ stages in bruxism group were (45.7 ± 7.1)% and (19.2 ± 4.9)%, while the control group were (52.9 ± 5.8)% and (13.3 ±5.3)% respectively. The sleep efficiency and the latency of sleep were (84.0 ± 8.0)% and (39.33 ± 28.73) min in bruxism group, and(94.0 ± 3.7)% and (10.27 ± 7.57) min in the control group respectively. The difference was statistically significant Conclusions The sleep structure is inordinate in bruxism children.
