深圳市某区中、小学生患龋病的现况分析

Epidemiology study on prevalence of dental caries among some pupils and middle school students in Shenzhen

目的了解深圳市某区中小学生龋病流行状况,为进一步开展牙病防治工作提供依据。方法2003-2007年每年对深圳市松岗第一小学和松岗中学全校学生进行口腔龋病检查并记录,分析两所学校学生的龋患率、龋齿发生率及龋均,并对两所学校学生的龋齿患病情况进行动态比较分析。结果小学生的历年龋病发生率和患病率均高于中学生;小学生的龋病发生率和患病率呈下降趋势,松岗中学的龋病发生率随时间发展呈下降趋势,龋患率较为平稳。结论应将小学生作为龋病防治的重点人群,同时加强中学阶段牙病防治的健康教育工作。

Objective To study the prevalence of dental caries among students of primary and secondary school in some district of Shenzhen city, and to provide evidence for further oral health care. Methods Oral examinations were conducted for students in Songgang first primary school and Songgang middle school from 2003 to 2007, prevalence rate, activity rate and the average of decayed teeth were analyzed and compared between two sehools. Results The prevalence rate,incidence rate of decayed teeth in pupils were lower than that in middle school students each year（ P 〈 0. 0001 ）, The prevalence rate,incidence rate of decayed teeth in pupils were decreasing byyear（2CMH =38. 587 ,P 〈 0. 0001;X2CMH =90. 138,P 〈 0. 0001 ） . In middle school students, the prevalence rate was decreasmg（x2CMH = 11. 848, P = 0.0185 ）, while the incidence rate was relatively stable 2 （X2CMH = 5. 569, P = 0. 2337 ）. Conclusion We should pupils as emphasis for dental caries prevention, while strengthen the healtheare education among middle school students for dental caries prevention.
