The aim of this study was to verify the correlation of self-reported sleep and awake bruxism with demographic characteristics, oral behaviors, anxiety, temporomandibular disorder (TMD) signs and symptoms, sleep quality, and orthodontic treatment history in dental students. A total of 104 students of Dentistry located in Paraná (South Brazilian State) answered the following self-administered questionnaires: Oral Behavior Checklist, State Anxiety Inventory, TMD signs and symptoms questionnaire, and the Pittsburgh Sleep Quality Index. Associations between possible awake bruxism (AB) and sleep bruxism (SB) with sleep quality, anxiety, and TMD were analyzed by Poisson Regression with robust variance. The significance level adopted was 5%. The frequency of AB and SB was 76% and 55.8%, respectively. A statistically higher frequency of AB was observed in students who had the following conditions: use of psychotropic medication, physical activity practitioners, moderate or high level of anxiety, more oral behaviors, sleep disorders, and sleep bruxism. Sleep bruxism was diagnosed more frequently in students who presented moderate or high levels of anxiety, oral behaviors, and sleep disorders. The frequency of TMD reported was higher in students with SB, as well as in those with AB. In conclusion, lifestyle, moderate and high anxiety levels, and sleep disorders are associated with a higher prevalence of AB and SB. Furthermore, AB and SB are associated with a higher frequency of TMD reporting.
本研究的目的是验证牙科学生自我报告的睡眠磨牙症和清醒磨牙症与人口统计学特征、口腔行为、焦虑、颞下颌关节紊乱症（TMD）体征和症状、睡眠质量以及正畸治疗史之间的相关性。共有104名位于巴拉那州（巴西南部州）的牙科学生回答了以下自行填写的问卷：口腔行为检查表、状态焦虑量表、TMD体征和症状问卷以及匹兹堡睡眠质量指数。采用稳健方差的泊松回归分析了可能的清醒磨牙症（AB）和睡眠磨牙症（SB）与睡眠质量、焦虑和TMD之间的关联。采用的显著性水平为5%。AB和SB的发生率分别为76%和55.8%。在有以下情况的学生中观察到AB的发生率在统计学上更高：使用精神药物、体育活动从业者、中度或高度焦虑、更多口腔行为、睡眠障碍和睡眠磨牙症。在表现出中度或高度焦虑、口腔行为和睡眠障碍的学生中，睡眠磨牙症的诊断更为频繁。报告的TMD发生率在有SB的学生以及有AB的学生中更高。总之，生活方式、中度和高度焦虑水平以及睡眠障碍与AB和SB的较高患病率相关。此外，AB和SB与更高的TMD报告频率相关。
