The purpose of this study was to identify associations between definite sleep bruxism, as defined by the American academy of sleep medicine, and chronic stress and sleep quality.
Sleep bruxism was determined by use of questionnaires, assessment of clinical symptoms, and recording of electromyographic and electrocardiographic data (recorded by the Bruxoff device). The study included 67 participants. Of these, 38 were identified as bruxers and 29 as non-bruxers. The 38 bruxers were further classified as 17 moderate and 21 intense bruxers. Self-reported stress and self-reported sleep quality were determined by use of the validated questionnaires "Trier Inventory for the Assessment of Chronic Stress" (TICS) and the "Pittsburgh Sleep Quality Index" (PSQI).
No statistically significant association was found between sleep bruxism and self-reported stress or sleep quality. However, a significant association between specific items of chronic stress and poor sleep quality was identified.
The results of this study indicate an association between subjective sleep quality and subjective chronic stress, irrespective of the presence or absence of sleep bruxism.
Chronic stress and sleep quality do not seem to be associated with sleep bruxism. (clinical trial no. NCT03039985).
本研究旨在确定美国睡眠医学学会定义的明确性磨牙症与慢性应激和睡眠质量之间的关联。
通过问卷、临床症状评估和肌电图及心电图数据记录（由 Bruxoff 设备记录）来确定磨牙症。该研究纳入了 67 名参与者。其中 38 名被确定为磨牙者，29 名被确定为非磨牙者。38 名磨牙者进一步分为 17 名中度磨牙者和 21 名重度磨牙者。使用经过验证的“慢性应激评估特里尔量表”（TICS）和“匹兹堡睡眠质量指数”（PSQI）来确定自我报告的压力和自我报告的睡眠质量。
磨牙症与自我报告的压力或睡眠质量之间未发现统计学上的显著关联。然而，慢性应激的特定项目与睡眠质量差之间存在显著关联。
本研究结果表明，主观睡眠质量与主观慢性应激之间存在关联，无论是否存在磨牙症。
慢性应激和睡眠质量似乎与磨牙症无关。（临床试验编号：NCT03039985）
