Abstract: Objective To survey the oral health status of 12 years old in Shaanxi province,and provide a base line for oral health service. Methods According to the third national oral health survey criteria,the oral status of 788 children in Shaanxi province were examined.SPSS 13.0 software was used for statistical analysis. Results The prevalence of caries and DFT were 21.2% and 0.33 respectively.The prevalences had no significant differences between male and female,urban and rural area;High levels of DFT were recorded in countryside and in the female,when compared to the urban and the male opponents.The survey found that the filling rate of caries was only 5.4%,in urban and female were higher than rural and male(P<0.05).The detection rate of dental calculus and gingival bleeding were 21.2% and 71.2%,respectively.There were significant differences of Gingival bleeding prevalence between rural and urban area(P<0.01),but no significant difference between male and female(P<0.05).dental calculus prevalence between rural and urban area male and female had no significant difference(P>0.05). Conclusion Oral health status in Shaanxi province should be paid more attention to.More effective measures should be taken to control the prevalence of dental caries,increase filling rate,improve oral health status,and strengthen the oral health education.

摘要： 目的 了解陕西省12岁儿童口腔健康状况,为陕西省开展儿童口腔卫生保健工作提供基线资料。方法 按照第三次全国口腔健康流行病学调查要求,采用多阶段、分层、等容量、随机抽样的方法,抽取陕西省城乡6个地区788名12岁儿童进行口腔健康状况调查。调查内容包括:龋病及牙周健康状况。资料整理采用Epi Data软件进行录入,SPSS 13.0统计软件进行相关统计学分析。结果 患龋率和龋均分别为:21.2%、0.33;龋均在男女之间差异有统计学意义(P<0.05)。龋齿充填构成比仅为5.4%,且城市高于农村,女性高于男性(P<0.05)。牙龈出血的检出率为21.2%,城市高于农村地区(P<0.01),男女之间差异无统计学意义(P>0.05);牙石的检出率为71.2%。结论 陕西省12岁儿童龋齿充填率低,牙周卫生状况较差,应采取有效的预防措施,控制龋病发生。提高龋齿充填率,改善牙周状况,加强口腔卫生宣教,提高口腔健康状况。
