研究目的：睡眠磨牙症是一种在睡眠中伴有磨牙的下颌不自主运动。儿童睡眠磨牙症的患病率很高，可能导致频繁觉醒并改变日间功能。我们调查了睡眠结构，胃食管反流的发病率，白天的认知行为功能在一组儿童与睡眠磨牙症。设计患者：这项前瞻性试点研究包括10名儿童。多导睡眠图数据与pH探针分析进行了比较与10个年龄和性别匹配的控制。每例患者完成了牙科评估，夜间多导睡眠图，和认知行为测试（考夫曼简明智力测试和Achenbach儿童行为检查表）。结果：10名儿童中有8名有临床意义的磨牙症和2名患者有最近的牙齿脱落。除了磨牙症组的觉醒指数较高（36.7比20.7，p <0.007）外，患者和对照组的睡眠结构没有差异。夜间磨牙症在第2阶段和快速眼动睡眠中更常见，66%的病例伴有觉醒。磨牙症与胃食管反流或智力无关。然而，40%的患者在Achenbach儿童行为量表上的分数升高，表明存在显著的注意力和行为问题，唤醒指数与Achenbach儿童行为量表中的几个行为问题量表之间存在中度相关性结论：磨牙症儿童有较高的唤醒指数，这可能与注意力-行为问题的发生率增加有关。未来的研究调查儿童睡眠磨牙症将需要集中在行为问题，可能是普遍存在于这一人群。
Study Objectives: Sleep bruxism is an involuntary mandibular movement with tooth grinding during sleep. The prevalence of sleep bruxism in children is high and may lead to frequent arousals with altered daytime functioning. We investigated the sleep architecture, the incidence of gastroesophageal reflux, and the daytime cognitive behavioral functioning in a group of children with sleep bruxism.Design-Patients: This prospective pilot study included 10 children. Polysomnographic data with pH-probe analysis was compared with 10 age-and sex-matched controls. Each patient completed a dental evaluation, a nighttime polysomnogram, and cognitive behavioral tests (Kaufman Brief Intelligence Test and Achenbach Child Behavior Checklist).Results: Eight of 10 children had clinically significant bruxism and the 2 remaining patients had recent teeth exfoliation. There was no difference on sleep architecture between patients and controls, except for a higher arousal index for the bruxism group (36.7 vs 20.7, p < .007). Sleep bruxism occurred more frequently in stage 2 and rapid eye movement sleep, with arousals in 66% of the cases. There was no relationship of bruxism to gastroesophageal reflux or intelligence. However, 40% of the patients had elevated scores on the Achenbach Child Behavior Checklist, indicating significant attention and behavior problems, and there were moderate correlations between the arousal index and several of the behavior-problem scales from the Achenbach Child Behavior Checklist (0.5 to 0.6).Conclusions: The data suggest that children with bruxism have a higher arousal index, which may be associated with an increased incidence of attention-behavior problems. Future studies investigating pediatric sleep bruxism will need to focus on behavior issues that may be prevalent in this population.
