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.
