: To assess the association between self-reported awake bruxism (AB) and the chronotype profile among Brazilian, Portuguese, and Italian dental students.: A cross-sectional study involving 205 dental students was developed. Self-reported AB as well as information on sleep characteristics were collected from a questionnaire. The Morningness-Eveningness Questionnaire (MEQ) was used to measure the chronotype profile. Descriptive statistical analysis, the chi-square test, and univariate analysis were used to evaluate the factors associated with AB.: The prevalence of AB in all groups was 33.7%. The intermediate chronotype profile was the most prevalent (60.4%), and only 16.7% of the participants had the morning profile. The univariate analysis showed that older dental students (OR = 2.640, 95% CI 1.388-5.021) and those with the eveningness chronotype profile (OR = 3.370, 95% CI 1.302-8.725) are associated with AB.: Students over the age of 22 and those with the eveningness chronotype profile were prone to AB.
: 评估巴西、葡萄牙和意大利牙科学员自述觉醒性磨牙症（AB）与昼夜时型特征之间的相关性：开展了一项涉及 205 名牙科学员的横断面研究。从问卷中收集了自述 AB 以及睡眠特征信息。使用 Morningness-Eveningness Questionnaire（MEQ）来衡量昼夜时型特征。采用描述性统计分析、卡方检验和单变量分析来评估与 AB 相关的因素。: 所有组别的 AB 患病率均为 33.7%。中间型昼夜时型特征最为普遍（60.4%），仅有 16.7%的参与者具有早晨型特征。单变量分析显示，年龄较大的牙科学员（OR=2.640，95%CI 1.388-5.021）和具有夜间型昼夜时型特征的学员（OR=3.370，95%CI 1.302-8.725）与 AB 相关。: 年龄在 22 岁以上的学员和具有夜间型昼夜时型特征的学员更易发生 AB。
