摘　　要：目的 评价Cariostat龋易感检测技术用于评估3岁无龋儿童患病风险的准确性和有效性,为临床提供参考.方法 以北京市海淀区2所幼儿园2013年9月入园的所有3岁儿童为研究对象,家长签署知情同意书的儿童都接受了龋病患病状况检查和Cariostat龋易感性检测.对无龋儿童纵向追踪2年,观察儿童龋病的发病情况.比较高（龋态值为2.0、2.5、3.0）、中（龋态值为1.5）、低（龋态值为0、0.5、0.0）龋态值组3岁无龋儿童2年患龋率和龋病患病程度间的差异,评价Cariostat龋易感性检测技术用于患龋风险评价的有效性和准确性.结果 2013年2所幼儿园864名3岁儿童中无龋儿童共426名（49.3%）,426名无龋儿童中共312名（73.2%）儿童完成2年的纵向观察,结果显示2年患龋率为46.5%（145/312）.高龋态值组无龋儿童2年患龋率为88.9%（88/99）;低龋态值组无龋儿童2年患龋率为17.5%（21/120）.以3岁时无龋儿童的龋态值为评估指标,预测儿童未来2年患龋的灵敏度为60.7%,特异度为93.4%.结论 Cariostat龋易感性检测技术用于3岁无龋儿童可有效预测儿童的患龋风险,该检测技术可用于儿童口腔健康综合管理.Objective To evaluate the caries status of a cohort of 3-year-old caries-free children from 2 kindergartens in Beijing in a period of 2 years by using Cariostat caries activity test and to assess the sensitivity and specificity of Cariostat score as a caries risk indicator for caries-free children. Methods Totally 4263-year-old caries-free children from 2 kindergartens in Beijing were recruited in the present study. Informed consents were obtained from the children＆#39;s parents. Dental plaque samples of the children were collected and the Cariostat caries activity tests were conducted at baseline and once a year for 2 years. After two years, the caries status of the cohort children were re-evaluated and the caries incidences amongst children with high （2.0, 2.5, 3.0）, medium （1.5） and low （1.0, 0.5, 0.0） levels of Cariostat scores were compared and analyzed. Results Totally 8643-year-old children from 2 kindergartens were screened before the study startedand 426 （49.3%） children were caries free. After 2-year follow-up, 312 out of 426 （73.2%） remained in the study. The overall caries incident rate was 46.5% （145/312）. The caries incident rate of children with high level of Cariostat scores was 88.9% （88/99）, while the caries incident rates ofchildren with medium and low levels of Cariostat scores was 38.7% （36/93） and 17.5% （21/120）, respectively. The sensitivity and specificity of the Cariostat test in assessing the caries risk of 3-year-old caries-free children in a period of 2 years were 60.7% and 93.4%, respectively. Conclusions Cariostat caries activity test can be used as an indicator to predict the caries risk of 3-year-old caries-free children. Comprehensive caries management could be conducted for children in kindergartens based on the caries risk assessment results of caries experience and the Cariostat score.
