To evaluate the epidemiological characteristics of erosive tooth wear in primary school students aged 6-12 in Jinzhou, including: prevalence, severity, extent, intraoral distribution and associated risk factors.
The data collection consists of two parts: the first part is the clinical examination of the participants. All erupted teeth were clinically assessed by three calibrated examiners, and classified according to the basic erosive wear examination (BEWE); The second part is a questionnaire about demographic information, parafunctional movement and lifestyle, completed by the parents or their guardians.
A total of 1,469 children were included in this experiment; erosive tooth wear (ETW) prevalence (BEWE ≥ 1) was 54.9%. According to cumulative BEWE index, the proportion of different ETW severity (high, medium, low, none) was 6.8%, 16.3%, 27.0% and 49.9%, respectively. In an analysis of risk factors, family factor, age, gender, extracurricular study time, oral hygiene habit, bruxism, unilateral mastication and acid diet was associated with the prevalence of ETW.
This study shows that ETW has a high prevalence in students aged 6-12, and more common in deciduous molars and deciduous canine. Abrasion, attrition and erosion play an important role in ETW.
评估锦州市 6-12 岁小学生酸蚀牙磨损的流行病学特征，包括：流行率、严重程度、范围、口腔内分布以及相关危险因素。
数据收集包括两部分：第一部分是参与者的临床检查。由三名经过校准的检查者对所有萌出的牙齿进行临床评估，并根据基本酸蚀磨损检查（BEWE）进行分类；第二部分是关于人口统计学信息、口腔不良习惯运动和生活方式的问卷调查，由父母或其监护人完成。
共有 1469 名儿童参与了这项实验；酸蚀牙磨损（ETW）的流行率（BEWE≥1）为 54.9%。根据累积 BEWE 指数，不同 ETW 严重程度（高、中、低、无）的比例分别为 6.8%、16.3%、27.0%和 49.9%。在危险因素分析中，家庭因素、年龄、性别、课外学习时间、口腔卫生习惯、磨牙症、单侧咀嚼和酸性饮食与 ETW 的流行率相关。
本研究表明，6-12 岁学生中 ETW 的流行率较高，且在乳磨牙和乳尖牙中更为常见。磨耗、磨损和酸蚀在 ETW 中起重要作用。
