摘要
目的 通过多导睡眠监测分析儿童夜磨牙症患者睡眠电生理及睡眠结构方面的改变,初步探讨夜磨牙症与睡眠电生理的关系.方法 分别选择12例严重夜磨牙症儿童患者（磨牙症组）及11名健康儿童（健康对照组）进行多导睡眠监测,并行统计学分析.结果 磨牙症组儿童非快速动眼睡眠Ⅱ期及Ⅳ期所占比例分别为（45.7±7.1）%和（19.2±4.9）%,而健康对照组分别为（52.9±5.8）%和（13.3±5.3）%,差异均有统计学意义（P＜0.05）.磨牙症组儿童的睡眠效率[（84.0±8.0）%]及睡眠潜伏期[（39.33±28.73）min]与健康对照组相比[分别为（94.0±3.7）%和（10.27±7.57）min]差异均有统计学意义（P＜0.01）.结论 夜磨牙症儿童存在睡眠结构紊乱.
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.
