A possible relationship between sleep bruxism (SB) and several sleep disorders has been suggested in children, which could influence sleep quality and quality of life. This study aims to assess such correlations in a large sample of school children.
Parents of 741 consecutive children aged between 8 and 12 years filled the Sleep Disturbance Scale for Children (SDSC). It evaluated 45 items grouped in 8 components: duration of night-time sleep, sleep latency, bedtime problems, sleep quality, night awakenings, nocturnal symptoms, morning symptoms, and daytime sleepiness. An item evaluating parental-reported tooth grinding was also included. Correlation analysis was performed between parental-reported tooth grinding and all the other items.
A significant correlation between parental-reported tooth grinding and several sleep disorders concerning bedtime problems, night awakenings, nocturnal symptoms, and morning symptoms has been found. In general, correlation strength of significant pairs was low, ranging from 0.092 (sleep apnea) to 0.234 (movement while falling asleep).
Parental-reported tooth grinding in children is correlated, even if weakly, with some sleep disorders concerning the sphere of bedtime problems, night awakenings, nocturnal symptoms, breathing symptoms, and morning symptoms. Further studies are needed to confirm these findings, with particular regard to the consistency of correlation outcomes between the parental reports and the sleep laboratory measures.
有研究提示儿童睡眠磨牙症（SB）与多种睡眠障碍之间可能存在关联，这可能会影响睡眠质量和生活质量。本研究旨在对大量学龄儿童进行评估。
741 名 8 至 12 岁儿童的家长填写了儿童睡眠障碍量表（SDSC）。该量表评估了 45 个项目，分为 8 个部分：夜间睡眠时间、入睡潜伏期、就寝时间问题、睡眠质量、夜间觉醒、夜间症状、晨起症状和日间嗜睡。量表还评估了父母报告的磨牙情况。分析了父母报告的磨牙与所有其他项目之间的相关性。
父母报告的磨牙与几个与就寝时间问题、夜间觉醒、夜间症状和晨起症状有关的睡眠障碍之间存在显著相关性。一般来说，显著相关性的相关强度较弱，范围从 0.092（睡眠呼吸暂停）到 0.234（入睡时的运动）。
儿童父母报告的磨牙与一些涉及就寝时间问题、夜间觉醒、夜间症状、呼吸症状和晨起症状的睡眠障碍存在相关性，尽管相关性较弱。需要进一步的研究来证实这些发现，特别是要关注父母报告和睡眠实验室测量之间的相关性结果的一致性。
