Caries management measures of different intensities would be implemented according to caries risk level (Schematic diagram of the online intervention process of the experimental group.Functions of patients' mobile terminal. After collecting clinical examination data and questionnaire data of control group. Caries risk was also graded for participants in the control group, and then hierarchical management was conducted. In addition to offline preventive clinical operations (topical fluoridation, pit and fissure sealing) with the same frequency as the experimental group, the researchers also conducted regular interventions for children in the control group in classroom, including oral health education, diet instruction, teaching children how to choose and use fluoridated toothpaste, education on brushing methods, and encouraging children with caries to seek medical treatment in time. The interval of interventions was every 3 months for those at high risk, every 6 months for those at intermediate risk, and every 12 months for those at low risk.
