To determine the prevalence of tooth wear and its associated factors in schoolchildren aged 10-18, focusing on sex-based effect modification.
A cross-sectional study was conducted, with clinical assessments performed by two qualified examiners using the Basic Erosive Wear Examination (BEWE). Parents completed a questionnaire regarding potential risk factors. Data were analysed using stepwise logistic regression models.
The final analysis included 550 participants. Mild erosive tooth wear (BEWE = 1) was present in over one-third of participants, and 11.8% showed severe wear (BEWE = 3). Among questionnaire respondents (n = 417), 26.4% had high cumulative BEWE scores. In females, clenching (OR = 2.3) and dairy intake (OR = 0.4) were significantly associated with tooth wear. In males, significant factors included reflux (OR = 7.4), soft drink consumption (OR = 4.2), and dairy intake (OR = 0.2).
Over one-third of schoolchildren exhibited tooth wear. Dairy product consumption had a protective effect, and age was associated with increased severity. Sex acted as an effect modifier: teeth clenching was a risk factor for females, whereas reflux, salad dressing, and soft drink consumption were risk factors for males.
确定10至18岁学龄儿童牙齿磨损的患病率及其相关因素，重点关注基于性别的效应修饰。
进行了一项横断面研究，由两名合格的检查人员使用基本侵蚀性磨损检查（BEWE）进行临床评估。家长完成了一份关于潜在风险因素的问卷。使用逐步逻辑回归模型分析数据。
最终分析纳入550名参与者。超过三分之一的参与者存在轻度侵蚀性牙齿磨损（BEWE = 1），11.8%表现为重度磨损（BEWE = 3）。在问卷受访者（n = 417）中，26.4%的人累积BEWE得分较高。在女性中，紧咬牙（OR = 2.3）和乳制品摄入（OR = 0.4）与牙齿磨损显著相关。在男性中，显著因素包括反流（OR = 7.4）、软饮料消费（OR = 4.2）和乳制品摄入（OR = 0.2）。
超过三分之一的学龄儿童存在牙齿磨损。食用乳制品具有保护作用，年龄与严重程度增加相关。性别起到效应修饰作用：紧咬牙是女性的一个风险因素，而反流、沙拉酱和软饮料消费是男性的风险因素。
