Abstract

Objective: This study aimed to clarify differences in assessment of sleep bruxism (SB) using electromyography (EMG) among analysis periods with/without excluding time zones after going to bed (GB) and before getting up (GU).

Methods: Masseteric EMG of 22 outpatients clinically diagnosed as SB was measured. Sleep onset (SO) and waking up (WU) were determined using a wearable motion monitor. Numbers of EMG episodes for nine periods were scored: GB-GU, SO-WU and other seven periods with exclusion of 15 min or more.

Results: Number of episodes/h for SO-WU highly correlated with those for the other eight analysis periods. The number for GB-GU was significantly larger than that for SO-WU, whereas those for other seven analysis periods were not significantly different from that for SO-WU.

Conclusion: The results suggest efficacy of excluding some adequate time zones after GB and before GU with a possibility of wakefulness in SB assessment.

在睡眠磨牙症评估中，在有/没有排除时区的分析期间，睡前和起床前的咬肌电波形数。

目的：本研究旨在厘清使用肌电图（EMG）评估睡眠磨牙症（SB）在有/没有排除时区的分析时段（睡前（GB）和起床前（GU））的差异。方法：对22例临床诊断为SB的门诊患者的咬肌肌电图进行测量。使用可穿戴运动监测仪测定睡眠开始时间（SO）和醒来时间（WU）。对9个时段的肌电图发作次数进行评分：GB-GU、SO-WU等7个时段，排除15分钟及以上。结果：SO-WU的发作次数/h与其他8个分析时段的发作次数/h高度相关。GB-GU的数量显著大于SO-WU，而其他7个分析时期的数量与SO-WU没有显著差异。结论：结果提示在GB后和GU前排除一些适当的时区对SB评估有唤醒的可能。

期刊介绍： CRANIO: The Journal of Craniomandibular & Sleep Practice is the oldest and largest journal in the world devoted to temporomandibular disorders, and now also includes articles on all aspects of sleep medicine. The Journal is multidisciplinary in its scope, with editorial board members from all areas of medicine and dentistry, including general dentists, oral surgeons, orthopaedists, radiologists, chiropractors, professors and behavioural scientists, physical therapists, acupuncturists, osteopathic and ear, nose and throat physicians. CRANIO publishes commendable works from outstanding researchers and clinicians in their respective fields. The multidisciplinary format allows individuals practicing with a TMD emphasis to stay abreast of related disciplines, as each issue presents multiple topics from overlapping areas of interest. CRANIO''s current readership (thousands) is comprised primarily of dentists; however, many physicians, physical therapists, chiropractors, osteopathic physicians and other related specialists subscribe and contribute to the Journal.
