Even though bruxism has been shown to be associated with several psychological factors, few studies have been performed on its relationships with anger and frustration.
This study aimed to determine the association between self-reported awake and sleep bruxism and anger and frustration.
In this longitudinal observational study, 55 healthy adult participants with "possible" bruxism reported their experienced level of bruxism and several psychosocial factors and lifestyle factors for 28 consecutive days using a personal logbook. The logbook consisted of a daily diary and a weekly questionnaire composed of Dutch versions of validated questionnaires. The primary outcome data were analysed using multiple regression models.
An increase in SB of 1 unit (on a scale ranging from 1 to 10) was associated with an increase in the anger-scale of 0.03 units, and the frustration-scale of 0.04 units. However, the random intercepts were 0.22 for anger and 0.19 for frustration, meaning that there were major differences between individuals. For awake bruxism (AB), the effects were an increase of 0.04 for anger with a random intercept of 0.21 and an increase of 0.03 for frustration with a random intercept of 0.06. The effects of anger and frustration on both SB and AB were not statistically significant.
The association between anger and frustration and self-reported bruxism is small on group level. In individual cases, anger and frustration and self-reported bruxism may be co-existent.
尽管磨牙症已被证明与多种心理因素有关，但关于其与愤怒和挫折感之间关系的研究却很少。
本研究旨在确定自我报告的清醒和睡眠磨牙症与愤怒和挫折感之间的关联。
在这项纵向观察性研究中，55名有“可能”磨牙症的健康成年参与者使用个人日志连续28天报告他们经历的磨牙症水平以及一些社会心理因素和生活方式因素。该日志包括一本每日日记和一份每周问卷，问卷由经过验证的荷兰语版本问卷组成。主要结局数据使用多元回归模型进行分析。
睡眠磨牙症（SB）增加1个单位（范围为1至10）与愤怒量表增加0.03个单位以及挫折感量表增加0.04个单位相关。然而，愤怒的随机截距为0.22，挫折感的随机截距为0.19，这意味着个体之间存在重大差异。对于清醒磨牙症（AB），愤怒的影响是增加0.04，随机截距为0.21，挫折感的影响是增加0.03，随机截距为0.06。愤怒和挫折感对SB和AB的影响均无统计学意义。
在群体水平上，愤怒和挫折感与自我报告的磨牙症之间的关联很小。在个别情况下，愤怒、挫折感和自我报告的磨牙症可能同时存在。
