The prevalence of bruxism in the preschool population varies according to different investigations. The aim of this study was to investigate the prevalence of sleep bruxism and its relationship with social and orofacial factors in children aged 3 to 5 years. Three hundred forty-three preschool children were divided into two groups, one with nocturnal bruxism, as reported by parents, and another without this disorder. Questionnaires were distributed to the parents to determine the children's family social status and parafunctional habits at the time of the study. The clinical inspection confirmed the presence of certain parafunctional habits and the children's occlusal characteristics. The data obtained were analysed using descriptive statistics such as frequency chi-square tests to identify the influence of qualitative variables. Of the total sample, 28.9% of preschoolers presented sleep bruxism. The highest prevalence was observed in boys (61.6%) at the age of 5 years (41.4%). Characteristics associated with this pathology were lip incompetence, open bite, crossbite, and overbite, with < 0.05. Sleep bruxism in preschool children has a higher prevalence in boys and is more frequently expressed from 5 years of age. Open bite, overbite, and crossbite should be considered factors associated with parafunction.
根据不同调查，学龄前儿童磨牙症的患病率有所不同。本研究的目的是调查3至5岁儿童睡眠磨牙症的患病率及其与社会因素和口面部因素的关系。343名学龄前儿童被分为两组，一组是家长报告有夜间磨牙症的儿童，另一组是无此病症的儿童。在研究期间，向家长发放问卷以确定孩子的家庭社会地位和副功能习惯。临床检查确认了某些副功能习惯的存在以及儿童的咬合特征。使用描述性统计方法（如频率卡方检验）对获得的数据进行分析，以确定定性变量的影响。在总样本中，28.9%的学龄前儿童存在睡眠磨牙症。在5岁的男孩中患病率最高（61.6%）（41.4%）。与这种病症相关的特征是唇功能不全、开（牙合）、反（牙合）和深覆（牙合），P<0.05。学龄前儿童睡眠磨牙症在男孩中患病率较高，且在5岁起更频繁出现。开（牙合）、深覆（牙合）和反（牙合）应被视为与副功能相关的因素。
