Little is known about the epidemiological characteristics of sleep and awake bruxism (SB and AB) in adolescents. The aims of the study were: to assess the prevalence rates of self-reported SB and AB in Israeli adolescents; to determine the associations between SB/AB and several demographical, exogenous and psychosocial factors in Israeli adolescents; and to investigate the possible concordance between SB and AB. The study made use of a questionnaire. The study population included 1000 students from different high schools in the centre of Israel. Prevalence of self-reported SB and AB in the Israeli adolescents studied was 9·2% and 19·2%, respectively. No gender difference was found regarding the prevalence of SB and AB. Multiple variable regression analysis revealed that the following predicting variables were related to SB: temporomandibular joint sounds (P = 0·002) and feeling stressed (P = 0·001). The following predicting variables were related to AB: age (P = 0·018), temporomandibular joint sounds (P = 0·002), oro-facial pain (P = 0·006), and feeling stressed (P = 0·002) or sad (P = 0·006). A significant association was found between SB and AB; that is, an individual reporting SB had a higher probability of reporting AB compared with an individual who did not report SB (odds ratio = 5·099). Chewing gum was the most common parafunction reported by adolescents. The results of this study demonstrate that self-reports of AB and SB are common in the Israeli adolescents population studied and are not related to gender. The significant correlation found between SB and AB may be a confounding bias that affects proper diagnosis of bruxism through self-reported questionnaires only.
关于青少年睡眠磨牙症和觉醒磨牙症（SB和AB）的流行病学特征，人们了解甚少。本研究的目的是：评估以色列青少年自我报告的SB和AB的患病率；确定以色列青少年中SB/AB与一些人口统计学、外部因素和心理社会因素之间的关联；并调查SB和AB之间可能的一致性。该研究采用了问卷调查。研究人群包括来自以色列中部不同高中的1000名学生。在所研究的以色列青少年中，自我报告的SB和AB的患病率分别为9.2%和19.2%。在SB和AB的患病率方面未发现性别差异。多变量回归分析显示，以下预测变量与SB相关：颞下颌关节弹响（P = 0.002）和感到压力（P = 0.001）。以下预测变量与AB相关：年龄（P = 0.018）、颞下颌关节弹响（P = 0.002）、口面部疼痛（P = 0.006）、感到压力（P = 0.002）或悲伤（P = 0.006）。在SB和AB之间发现了显著关联；也就是说，与未报告SB的个体相比，报告SB 的个体报告AB的可能性更高（优势比 = 5.099）。嚼口香糖是青少年报告的最常见的副功能。本研究结果表明，在所研究的以色列青少年人群中，AB和SB的自我报告很常见，且与性别无关。在SB和AB之间发现的显著相关性可能是一种混杂偏倚，仅通过自我报告问卷会影响磨牙症的正确诊断。
