Erosive tooth wear (ETW) has become a crucial oral health problem over the decades in China.
To explore the prevalence and risk indicators of ETW among adolescents in Guangzhou, south China.
A cross-sectional survey of 720 participants was conducted in Guangzhou, using an equal-sized, stratified, multistage random sampling approach. The participants were from two different age groups (12- and 15-year-olds), 360 per group. The ratio of males to females was 1:1 in each group. ETW was recorded utilising the basic erosive wear examination (BEWE) index as the dependent variable. Independent variables included age, gender, region, socioeconomic status, dietary factors, oral health measures and others.
The prevalence rates (weighted) of ETW and dentin exposure (DE) were 56.1% and 26.2% among adolescents in Guangzhou, with mean teeth (weighted) of 1.8 ± 2.5 and 0.6 ± 1.5, respectively. No matter the prevalence or the mean teeth, the 15-year-olds were higher than the 12-year-olds; the mean teeth of ETW of males was higher than that of females; the mean teeth of ETW and DE of the adolescents of low socioeconomic status were higher than those of high socioeconomic status. Medium to high risk levels were found for 10.1%. In the multiple regression model, age, gender and taking acidic foods/drinks before sleep were associated with ETW.
Moderate ETW in the permanent dentition was common among adolescents in Guangzhou. However, the teeth involved were low. Dietary factors and demographics were the main risk indicators.
几十年来，在中国，侵蚀性牙齿磨损（ETW）已成为一个重要的口腔健康问题。
探索中国广州青少年 ETW 的流行率和风险指标。
采用等大小、分层、多阶段随机抽样方法，在中国广州对 720 名参与者进行了横断面调查。参与者分为两个不同年龄组（12 岁和 15 岁），每组 360 人。每组男女比例为 1:1。采用基本侵蚀性磨损检查（BEWE）指数作为因变量记录 ETW。自变量包括年龄、性别、地区、社会经济状况、饮食因素、口腔健康措施等。
广州青少年 ETW 和牙本质暴露（DE）的患病率（加权）分别为 56.1%和 26.2%，平均牙齿（加权）分别为 1.8±2.5 和 0.6±1.5。无论患病率还是平均牙齿，15 岁组均高于 12 岁组；男性 ETW 的平均牙齿高于女性；社会经济地位较低的青少年 ETW 和 DE 的平均牙齿高于社会经济地位较高的青少年。发现中到高风险水平为 10.1%。在多元回归模型中，年龄、性别和睡前吃酸性食物/饮料与 ETW 相关。
广州青少年恒牙有中度 ETW ，但涉及的牙齿较少。饮食因素和人口统计学是主要的风险指标。
