12岁人群恒牙龋病抽样调查分析研究

A Sampling Survey and Analysis of the Permanent Teeth Caries Development Status Quo Among Population Aged 12 Years in Beijing Chaoyang District in 2010

目的了解北京市朝阳区12岁人群恒牙龋齿患病情况及采取的防治措施,为朝阳区口腔疾病防治工作提供信息支持。方法采用分层、整群随机抽样的方法,抽取12岁常住人口361人。按照《北京市2010年口腔健康流行病学调查方案》中临床检查牙列状况的检查方法和标准,检查全口恒牙牙冠龋病情况,计算出患龋率、龋均、龋齿充填率及窝沟封闭率。结果(1)12岁人群患龋率为28.81%、龋均为0.48、龋齿充填率为45.09%,第一恒磨牙窝沟封闭率为44.88%。农业户口与非农业户口龋均差异有统计学意义(P<0.01);男生与女生患龋率及龋均差异有统计学意义(P<0.05,P<0.01)。(2)与2005年第3次全国口腔健康流行病学调查全国地区资料的比较,两者患龋率差异及龋均差异无统计学意义(P>0.05,P>0.05)。两者龋齿充填率差异及窝沟封闭率差异有统计学意义(P<0.01,P<0.01)。结论朝阳区12岁人群恒牙龋齿发病率较低,窝沟封闭能有效地预防龋齿的发生。

Objective To understand the permanent teeth caries development status quo and preventive and treatment strategies a mong population aged 12 years in Beijing Chaoyang District, thus to provide scientific basis for oral disease prevention and treatment poli cies in the district. Methods The method of stratification and random cluster sampling was used. A sample of 361 resident population aged 12 years were drawn. The caries on the crowns of permanent teeth were assessed according to the Guideline for the 2010 Beijing Oral Health Survey, thereafter the caries rate, decayed, missing and filling teeth（DMFT） of permanent teeth, caries filling rate and pit and fis sure sealing rate were calculated. Results （1）The caries rate, permanent teeth DMFT, caries filling rate and pit and fissure sealing rate among population aged 12 years were 28.81% ,0.48, 45.09% and 44.88% respectively. There was significant difference in permanent teeth DMFT between population of agriculture registered permanent residence and those of non agricultural registered permanent resi dence （P 〈 O. 05 ,P 〈 O. O1 ）. There were significant differences both in caries rate and permanent teeth DMFT between male population and female population （ P 〈 O. 05 ,P 〈 0. O1 ）.（2） Compared with the results of 3rd National Oral Health Survey in 2005, there was no sig nificant difference both in caries rate and permanent teeth DMFT（P 〉 O. 05 ,P 〉 0.05 ） , but caries filling rate and pit and fissure sealing rate are higher （P 〈 0.01 ,P 〈 0.01 ）. Conclusion The morbidity of permanent teeth caries among population aged 12 years in Beijing Chaoyang District is low and pit and fissure sealant can effectively prevent the development of permanent teeth caries.
