重庆市4~17岁孤儿口腔健康现状调查分析

目的 了解重庆市4~17岁孤儿口腔健康现状及其流行趋势，为制定孤儿口腔保健计划提供依据。方法 根据第三次全国口腔健康流行病学抽样调查方案，抽取重庆市江北区某儿童福利院孤儿为调查对象，对该福利院317名孤儿进行口腔健康检查，记录龋齿、牙龈出血和牙结石情况。采用SPSS 17.0软件对数据进行统计分析。结果 重庆市岁孤儿乳牙和恒牙的患龋率及龋均分别为50.00%、1.94±2.81和39.53%、0.90±1.38，男女之间差异无统计学意义（P>0.05）。恒牙患龋率 12岁及以下年龄组与12岁以上年龄组间有统计学差异（P<0.05）。第一恒磨牙患龋率为35.25%，女性高于男性（P<0.05）。龋齿充填率及第一恒磨牙窝沟封闭率均为0.00%。牙龈出血检出率为78.22%，牙结石检出率为67.66%。结论 重庆市4~17岁孤儿口腔健康现状不佳，牙科服务利用率极低，在今后的工作中，应将这部分人群纳入口腔健康预防保健的重点人群之列。

Methods According to the third national oral health investigation of epidemiology, the dental caries, gingival bleeding and calculus was examined among 317 orphan living in Chongqing, by cluster sampling. The statistical software SPSS 17.0 was used for the data analysis. Results In primary and permanent teeth, the prevalence of dental caries and mean DMFT (dmft) were found to be 50.00%, 1.94±2.81 and 39.53%, 0.90±1.38. There were no significant difference between female and male (P>0.05). But there was significant difference of the prevalence of per-manent tooth caries between the age group under 12 (include 12) and above 12 (P<0.05). It was also found that 35.25% of the orphan children and adolescents had caries in the first permanent molar, and there was significant difference between female and male (P<0.05). Neither of the caries teeth above was treated nor the healthy teeth were sealed. The prevalence rate of gingival bleeding was 78.22%, and the calculus rate was 67.66%. Conclusion The oral status of the orphan is poor, and this community has experienced a low utilization of preventive or therapeutic oral health services. In the future work, orphans should be considered asapriority group when makeplansfor oral health care.
