Abstract：
BACKGROUND: Sleep hygiene measures and meditation may reduce stress and improve sleep quality, but their effect on the occurrence of sleep bruxism in children has not yet been investigated.
OBJECTIVE: To explore the effects of sleep hygiene measures combined with mindfulness meditation (relaxation audio) in the management of probable sleep bruxism (SB) in children.
METHODS: This clinical trial (no. NCT04501237) randomized 36 children with 3-8 years of age. Probable SB detection was performed according to the criteria established by the International Consensus on The Assessment of Bruxism-2018. Intervention group was instructed to practice sleep hygiene measures and mindfulness meditation (i.e., the use of a digital app to broadcast audio relaxation) each night before bedtime for 5 weeks; control group did not receive guidance for therapies. Parents completed a bruxism diary for 5 weeks, and the outcome was the number of SB episodes-day reported in the week (ranging from 0 to 7) in each period. A multilevel mixed-effects Poisson regression model was performed.
RESULTS: A total of 32 children (mean age: 6.1 years) completed the study. The children who received the therapies related to sleep hygiene measures and mindfulness meditation had a reduction in the SB incidence rate ratio (IRR) of 46% (IRR = 0.54 [Confidence Interval 95%, 0.45-0.65]) during a 5-week observation period. The sensitivity analyses did not show relevant changes in the measure of the effect.
CONCLUSIONS: Sleep hygiene measures combined with mindfulness meditation reduced the SB in children.

摘要：
背景：睡眠卫生措施和冥想可以减轻压力并提高睡眠质量，但是它们对儿童睡眠磨牙症发生的影响尚未得到研究。
目的：探讨睡眠卫生措施结合正念冥想（放松音频）在治疗儿童可能的睡眠磨牙症（SB）中的作用。
方法：本临床试验（编号：NCT04501237）随机分配36名3-8岁儿童。可能的SB检测是根据“2018年布鲁塞尔病评估国际共识”确立的标准进行的。干预组被指示练习睡眠卫生措施和正念冥想(即，使用数字应用程序播放音频放松)每晚睡前5周；对照组没有接受治疗指导。父母完成了5周的磨牙症日记，结果是每个时期内每周报告的SB发作次数（范围从0到7）。建立多级混合效应泊松回归模型。
结果：共有32名儿童（平均年龄：6.1岁）完成了研究。接受与睡眠卫生措施和正念冥想相关的疗法的儿童的SB发生率（IRR）降低了46％（IRR=0.54[置信区间95％，0.45-0.65]）在5周的观察期内。敏感性分析未显示效果度量的相关变化。
结论：睡眠卫生措施与正念冥想相结合可降低儿童的SB。
