Objective: This study aimed to evaluate the effectiveness of a caries-risk preventive 3 3 program using different strategies in young children. After a 2-year longitudinal study, a comparative study was conducted to evaluate the effect based on risk assessment. Methods: A total of 322 children (3 years old) from four kindergartens in the Dongcheng and Xicheng districts of Beijing were randomly selected and divided into two groups: experimental (n = 155) and control (n = 167). Oral examinations, the Cariostat test, and a questionnaire survey were conducted. The criteria for diagnosing dental caries were based on the International Caries Detection and Assessment System (ICDAS II, 2002). The caries risk was assessed based on the caries risk assessment tool (CAT) recommended by the American Academy of Pediatric Dentistry and combined with the results of the Cariostat test and survey. The children in the experimental and control groups were subdivided into high-, medium-, and low-risk level subgroups. On the basis of receiving regular oral examinations and participated in Beijing free fluoride foam project. The frequencies of fluoride foam use and oral health education were increased for the children in the experimental group, particularly those from the medium- and high-risk subgroups. The two groups were re-examined 1 and 2 years after the interventions to analyze the differences in the development of new cavitation caries and evaluate the effects of the preventive measures. Results: At baseline, no differences in caries were observed between the experimental and control groups. Two years after the longitudinal study, the new cavitation caries rates, dmf3-6s, and dmf4-6s among children in the high-risk subgroup within the experimental group were significantly lower than those in the control group (p < 0.05). At age 5, the surface caries in the high-risk children (dmf3–4s and dmf5–6s) in the experimental group were lower than those in the control group (p < 0.05). Furthermore, the probability of mild caries (d12) transforming into no caries (D0) at 5 years of age was 60.1% in the experimental group and 46.1% in the control group (p < 0.05). Conclusion: Two years of comprehensive caries management reduced the occurrence of new caries in children with a high risk of caries and inhibited the formation of cavity caries to a certain extent. Effective caries prevention and treatment measures can promote the remineralization of early caries.

研究目的：本研究旨在评估针对幼儿的不同策略龋病风险预防方案的有效性。在开展为期2年的纵向研究后，本研究进一步基于风险评估开展对比研究以评价干预效果。
研究方法：本研究从北京市东城区与西城区的4所幼儿园中，随机选取322名3岁儿童，将其分为实验组（n=155）与对照组（n=167）。所有受试儿童均接受口腔检查、龋活性试验（Cariostat test）及问卷调查。龋病诊断标准采用国际龋病检测与评估系统（International Caries Detection and Assessment System，ICDAS II，2002）。龋病风险评估采用美国儿童牙科学会（American Academy of Pediatric Dentistry）推荐的龋病风险评估工具（Caries Risk Assessment Tool，CAT），结合龋活性试验与问卷调查结果进行综合评定。将实验组与对照组儿童进一步划分为高、中、低三个风险亚组。两组儿童均定期接受口腔检查，并参与北京市免费氟化泡沫项目，其中实验组儿童（尤其是中、高风险亚组儿童）的氟化泡沫使用频率与口腔健康教育频次均有所提升。分别于干预后1年与2年对两组儿童进行复查，分析新发龋洞的发生差异，评估预防措施的干预效果。
研究结果：基线时，实验组与对照组儿童的龋病基线情况无显著差异。纵向研究开展2年后，实验组高风险亚组儿童的新发龋洞率、dmf3-6s与dmf4-6s均显著低于对照组（p<0.05）。当儿童年满5岁时，实验组高风险儿童的牙面龋损情况（dmf3–4s与dmf5–6s）均显著优于对照组（p<0.05）。此外，实验组5岁儿童中轻度龋损（d12）转为无龋状态（D0）的概率为60.1%，对照组为46.1%（p<0.05）。
研究结论：为期2年的综合龋病管理可降低高龋风险儿童的新发龋病发生率，在一定程度上抑制龋洞形成。有效的龋病防治措施可促进早期龋损的再矿化。
