摘　　要：目的了解北京市老年人群的龋病患病情况,为制定口腔卫生保健政策提供参考。方法采用多阶段分层等容量随机抽样方法,抽取北京市65～74岁城乡常住人口792人,男女各半,参照《第三次全国口腔健康流行病学抽样调查方案》检查龋齿情况,计算龋均和患龋率。结果北京市792名受检者恒牙患龋率为66.03%,龋均为2.37;根龋的患龋率为26.39%,龋均为0.46;龋齿充填率为23.88%,其中根龋充填率为5.81%,根龋充填率在城乡的差异有统计学意义(χ2=16.87,P<0.01)。结论北京市老年人根龋的患龋率和龋均呈现上升趋势,充填率低,应合理配置城乡口腔医疗资源,采取综合防治措施。Objective To study the prevalence of dental caries among senior citizens in Beijing,thus to provide reference data on oral health guidance.Methods An equal-sized stratified multi-stage randomly sampling design was used to draw a sample of 792 in both urban and rural areas in Beijing,aged from 65 to 74,with the same number in gender.The caries on the crowns and the roots of permanent teeth were assessed according to The Guideline for the 3rd National Oral Health Survey.The prevalence rate and the decayed filled tooth index（DFT）were calculated.Results The mean DFT is about 2.37,caries prevalence rate on permanent tooth is 66.03%;The mean DFT on root caries is about 0.46,root caries prevalence rate is 26.39%.Only 23.88% caries and 5.81% root caries were filled.There is no significant statistical difference between rural and urban area,but indexes and rates of female are much higher than those of male.Conclusion The date suggested both a high level of root caries and a low level of filled rate in Beijing.Especially in rural areas,more efforts should be putted on this problem.
