东北地区老年人群患龋状况的抽样调查报告

目的了解东北地区老年人群的患龋状况，为制定防治方案提供基线资料。方法采用多阶段分层等容量随机抽样的方法，按照世界卫生组织《口腔健康调查基本方法》（第4版）的原则，对东北三省2 364名65～74岁老年人的冠龋和根龋情况进行检查，应用SPSS 12.0统计软件对三省患龋情况进行分析。结果1）东北地区65～74岁老年人的患龋率为67.5%，龋均为2.68，因龋充填牙构成比为10.82%；2）东北地区65～74岁老年人的冠龋患龋率为66.4%，龋均为2.55，因龋充填牙构成比为11.37%；3）东北地区65～74岁老年人的根龋患龋率为48.4%，龋均为1.64，因龋充填牙构成比为1.8%。结论东北三省老年人群患龋率高，治疗率低。开展针对老年人的社区口腔卫生服务是提高老年人口腔健康状况的前提。
