A cross-sectional study was performed to assess the association between possible sleep bruxism (SB) and awake bruxism (AB) with sleep characteristics and chronotype (i.e. circadian cycle preference).
One-hundred-nineteen young adults filled out a self-reported questionnaire to assess SB and AB, a questionnaire about daily life aspects, as well as the Morningness-Eveningness Questionnaire (MEQ) to profile chronotype.
The frequency of self-reported SB and AB was 25.2% and 37.0%, respectively. Both SB and AB were significantly more frequent in females than males. Most participants had an intermediate chronotype profile (n = 85; 71.4%). Neither SB (p = 0.556) nor AB (p = 0.334) were associated with chronotype. Nightmares were more prevalent among individuals with possible SB (38.3%). Difficulty concentrating in daily activities was more frequently reported among individuals with AB (51.9%).
There was no association between possible SB and AB or the chronotype profiles among Italian dental students.
开展一项横断面研究，以评估可能的睡眠磨牙症（SB）和清醒磨牙症（AB）与睡眠特征及昼夜节律类型（即昼夜周期偏好）之间的关联。
119名年轻成年人填写了一份自我报告问卷，以评估SB和AB，一份关于日常生活方面的问卷，以及晨型-夜型问卷（MEQ）以描绘昼夜节律类型。
自我报告的SB和AB的频率分别为25.2%和37.0%。女性的SB和AB发生率均显著高于男性。大多数参与者具有中间型昼夜节律类型（n = 85；71.4%）。SB（p = 0.556）和AB（p = 0.334）均与昼夜节律类型无关。噩梦在可能患有SB的个体中更为普遍（38.3%）。在患有AB的个体中，日常活动难以集中注意力的情况报告更为频繁（51.9%）。
在意大利牙科学生中，可能的SB和AB与昼夜节律类型之间不存在关联。
