青岛市城阳区初中学生牙酸蚀患病情况调查

THE PREVALENCE OF TOOTH EROSION AMONG JUNIOR HIGH SCHOOL STUDENTS IN CHENGYANG DISTRICT OF QINGDAO,CHINA

目的调查青岛市城阳区初中学生牙酸蚀的患病情况及其相关影响因素,为该地区牙酸蚀的预防提供参考。方法选取青岛市城阳区2所初中学生共807人,根据Van Rijikom改良标准,采用牙酸蚀患病情况调查表调查牙酸蚀发病率,问卷调查牙酸蚀的相关因素。结果青岛市城阳区初中学生牙酸蚀的患病率为56.01%,城区组患病率(64.10%)高于农村组(47.89%),差异有显著性(χ~2=21.537,P<0.05);男性患病率(57.95%)与女性(54.02%)比较差异无显著性(P>0.05)。父母受教育程度高(中专及其以上)的学生牙酸蚀患病率高于受教育程度低(高中及其以下)者,学生喝酸性饮料频率高(每天≥1次)者牙酸蚀患病率高于频率低(每天<1次)者(χ~2=14.806~45.786,P<0.05)。结论青岛市城阳区初中学生牙酸蚀的患病率处于较高水平,其发生与酸性饮料的饮用密切相关。预防牙酸蚀应当减少酸性饮料的饮用频率。

Objective To investigate the prevalence of and influencing factors for tooth erosion among junior high school students in Chengyang District of Qingdao,China,and to provide a basis for the prevention of tooth erosion in the area. Methods A total of 807 students from two junior high schools in Chengyang District of Qingdao were enrolled as subjects.Based on the modified Van Rijikom criteria,the incidence of tooth erosion was investigated by the questionnaire regarding the development of tooth erosion;the influencing factors for tooth erosion were evaluated by questionnaire. Results The incidence of tooth erosion was56.01% among those junior high school students in Chengyang District of Qingdao.Students in the urban area had significantly higher incidence of tooth erosion than those in the rural area（64.10% vs 47.89%,χ^2=21.537,P〈0.05）.There was no significant difference in the incidence of tooth erosion between males and females（57.95% vs 54.02%,P〉0.05）.The students whose parents had a high educational level（secondary school or above）had a significantly higher incidence of tooth erosion than those whose parents had a low educational level（senior high school or below）.The students who drunk acidic beverage at a high frequency（no less than once per day）had a significantly higher incidence of tooth erosion than those who drunk acidic beverage at a low frequency（less than once per day）（χ^2=14.806-45.786,P〈0.05）. Conclusion The junior high school students in Chengyang District of Qingdao have a high incidence of tooth erosion.The development of tooth erosion is closely related to acidic beverage consumption.Reducing the consumption of acidic beverage is recommended for the prevention of tooth erosion.
