Objective: To understand the influencing factors of dental caries in children aged 1-3 years in Baotou City, and to construct a prediction model to identify high-risk groups of children, so as to provide a basis for the development of targeted caries prevention and intervention strategies, and reduce the incidence of dental caries in children. Methods: From December 2021 to November 2023, children aged 1-3 years from 18 Junior classes of kindergarten were randomly selected as observation objects. All children underwent oral examinations and the number of deciduous teeth with enamel development defects was counted. In addition, a questionnaire survey was conducted, which was composed of general demographic information and related factors. The related factors of children's dental caries were screened, the prediction model was established, and the discrimination and calibration ability of the model were evaluated. Results: Sleeping with bottles or nipples, eating desserts and candy, enamel development defects, and late age of starting brushing were risk factors for dental caries in children aged 1-3 years in Baotou city; high frequency of helping children brush their teeth, regular oral examination, high education of parents and calcium supplementation during pregnancy were the protective factors of dental caries in children aged 1-3 years in Baotou (P＜0.05). The prediction model of dental caries in children aged 1-3 years in Baotou was established, the ROC curve analysis showed that the AUC of the model was 0.919, the sensitivity was 75.7%, and the specificity was 70.9%. The prediction model had high calibration ability. Conclusion: The dental caries of children aged 1-3 years in Baotou City may be related to many factors, such as parents' educational background, calcium supplementation during pregnancy, and age of starting to brush teeth. The dental caries prediction model can provide a reference tool for the management of caries in children in this area.
