Tooth wear has been investigated in numerous countries, and the prevalence has varied. However, the data on tooth wear in China are scarce. The aim of this study was to describe the prevalence of tooth wear and to investigate the relative indicators associated with tooth wear in 12- and 15-year-old adolescents in Wuhan City, Hubei Province, Central China.
A cross-sectional descriptive study was undertaken among 720 adolescents in Hubei Province, Central China. The age groups in this study were 12- and 15-year-old, and each group consisted of 360 participants in which females and males represented 50 % each. A modified version of the Basic Erosive Wear Examination (BEWE) tooth wear index was used for the buccal, cervical, occlusal/incisal and lingual surfaces of all of the teeth in the 720 adolescents. All of the participants were asked to answer a questionnaire consisting of questions about their current and historical dietary habits and oral hygiene.
The prevalence of tooth wear was 18.6 and 89.4 % in 12- and 15-year-old adolescents, respectively. The prevalence rates of dentin exposure were 1.9 and 5.6 %, respectively. A significantly higher prevalence of tooth wear and dentin exposure in 15-year-old adolescents was found than in 12-year-old adolescents (p < 0.001 and p = 0.011). Several factors such as drinking soft drinks and fruit juices immediately after sports, taking aspirin, reflux, unilateral chewing, tooth brushing once daily or less often, duration of brushing less than 2 min and swimming in the summer were found to be associated with tooth wear.
Tooth wear in 12- and 15-year-old adolescents in Central China is a significant problem and should receive greater attention. The prevalence of tooth wear increases with age and associated with socio-behavioral risk factors.
牙齿磨损在许多国家都有研究，患病率各不相同。然而，中国关于牙齿磨损的数据很少。本研究的目的是描述中国中部湖北省武汉市12岁和15岁青少年牙齿磨损的患病率，并调查与牙齿磨损相关的相关指标。
对中国中部湖北省的720名青少年进行了一项横断面描述性研究。本研究的年龄组为12岁和15岁，每组由360名参与者组成，其中女性和男性各占50%。使用改良版的基本侵蚀性磨损检查（BEWE）牙齿磨损指数对720名青少年所有牙齿的颊面、颈部、咬合面/切缘和舌面进行评估。所有参与者都被要求回答一份问卷，问卷内容包括他们当前和过去的饮食习惯及口腔卫生情况。
12岁和15岁青少年的牙齿磨损患病率分别为18.6%和89.4%。牙本质暴露的患病率分别为1.9%和5.6%。发现15岁青少年的牙齿磨损和牙本质暴露患病率显著高于12岁青少年（p<0.001和p=0.011）。发现一些因素与牙齿磨损有关，如运动后立即饮用软饮料和果汁、服用阿司匹林、反流、单侧咀嚼、每天刷牙一次或更少、刷牙时间少于2分钟以及夏季游泳。
中国中部12岁和15岁青少年的牙齿磨损是一个严重问题，应得到更多关注。牙齿磨损的患病率随年龄增长而增加，并与社会行为风险因素有关。
