目的了解2014年成都市中小学生龋齿情况。方法由经培训具有执业医师资格的口腔专业人员按《2014年全国体质与健康调研工作手册》对25所市级监测点校9 901人的龋齿情况进行检测。结果乳牙龋患率合计为34.5%,其中男生为34.8%,女生为34.2%,乡村学生乳牙龋患率大于同性别的城市学生。恒牙龋患率合计为13.5%,其中男生为11.4%,女生为15.7%,城市学生的恒牙龋患率大于同性别乡村学生,女生的恒牙龋患率大于同区域男生。龋补率总体较低,城市学生的乳牙龋补率和恒牙龋补率最高分别为12.4%和12.5%,乡村学生最高分别为1.2%和2.7%。结论学生龋齿的患病率高、危害大、影响长远,建议采取加强口腔卫生宣教、合理使用氟化物、开展窝沟封闭、完善相关的保障制度等综合措施,切实减少学生龋齿发生。
Objective To understand the dental caries status of primary and secondary school students in Chengdu in 2014. Methods Toothpaste of 9 901 people from 25 municipal-level monitoring schools was tested by oral professionals with trained qualifications according to the 2014 National Manual for Physical Fitness and Health Survey. Results The total caries prevalence rate was 34.5%, with 34.8% for boys and 34.2% for girls. The prevalence of deciduous teeth in rural students was higher than that of urban students of the same gender. The total caries prevalence in permanent teeth was 13.5%, including 11.4% for boys and 15.7% for girls. The prevalence of permanent dental caries in urban students was higher than that of same-sex rural students. The prevalence of permanent dental caries among girls was higher than that of boys in the same region. The caries replacement rate was generally low. The highest rates of deciduous teeth caries and permanent teeth caries in urban students were 12.4% and 12.5% respectively, while the highest among rural students was 1.2% and 2.7% respectively. Conclusions The prevalence of dental caries in students is high, harmful and long term. It is suggested that comprehensive measures be taken to strengthen education on oral hygiene, rational use of fluoride, enclosure of pit and fissure, improvement of relevant guarantee system and so on, so as to reduce the incidence of dental caries in students.
