To construct an online caries management platform and evaluate its efficacy in children's caries prevention based on caries risk.
The study participants were second-grade pupils. The caries risk assessment tool (CAT) was used to grade caries risk for all participants, who were randomly divided into the experimental (114 pupils) and control (111 pupils) groups. The experimental group used the Internet for caries management, while the control group was managed by traditional lecturing in classroom. The caries status of each surface of the first permanent molars was recorded. The basic information and oral health knowledge, attitude, and behaviors of participants were collected by questionnaire. One year later, outcome data were collected. Pearson's chi-squared test was used to analyze the caries risk assessment items and oral health behaviors. The Mann-Whitney -test was used to analyze the decayed-missing-filled surfaces (DMFS) index, plaque index, and scores of oral health knowledge and attitude. < 0.05 was considered statistically significant. This study was available on the website of Chinese Clinical Trials Register (No: MR-44-22-012947).
After 1 year, the oral health knowledge score was improved by 20.58% ( < 0.001) in the experimental group and 6.02% in the control group. The plaque index was improved by 49.60% ( < 0.001) in the experimental group and 21.01% in the control group. The DMFS index increased in both groups but there were no significant differences ( = 0.608). The experimental group had a better improvement effect in caries risk assessment items than the control group, including "whether the frequency of eating sugary snacks or drinks between meals is more than 3 times/day" ( = 0.033) and the use of fluoridated toothpaste ( = 0.020). The experimental group was better than the control group in reported oral health behaviors, including frequency of eating sweets before sleep ( = 0.032), brushing time ( = 0.001), and the filled rate (proportion of FS in DMFS) of first permanent molars ( = 0.003).
The online caries management platform showed more advantages than traditional lecturing in improving oral health knowledge and behaviors (oral hygiene practice, sugar consumption behavior, and medical treatment behavior). This platform provides a reliable implementation path for the occurrence and continuous improvement of oral health-related behaviors.
构建在线龋病管理平台，并基于龋病风险评估，评价其在儿童龋病预防中的效果。
研究对象为二年级小学生。采用龋病风险评估工具（Caries Assessment Tool，CAT）对所有参与者进行龋病风险分级，然后将其随机分为实验组（114 人）和对照组（111 人）。实验组通过互联网进行龋病管理，对照组则采用传统课堂讲授方式。记录每位参与者第一恒磨牙各面的龋病状况。通过问卷调查收集参与者的基本信息和口腔健康知识、态度和行为。1 年后收集结局数据。采用 Pearson 卡方检验分析龋病风险评估项目和口腔健康行为，采用 Mann-Whitney U 检验分析龋失补牙面（decayed-missing-filled surfaces，DMFS）指数、菌斑指数和口腔健康知识与态度得分。 < 0.05 为差异有统计学意义。本研究已在临床试验注册网站（注册号：MR-44-22-012947）注册。
1 年后，实验组口腔健康知识得分提高了 20.58%（ < 0.001），对照组提高了 6.02%。实验组菌斑指数提高了 49.60%（ < 0.001），对照组提高了 21.01%。两组 DMFS 指数均增加，但差异无统计学意义（ = 0.608）。实验组在评估项目中对龋病风险的改善效果优于对照组，包括“是否每日 3 次或以上在正餐之间进食含糖零食或饮料”（ = 0.033）和使用含氟牙膏（ = 0.020）。实验组在口腔健康行为方面优于对照组，包括睡前吃甜食的频率（ = 0.032）、刷牙时间（ = 0.001）和第一恒磨牙充填率（FS 在 DMFS 中的比例）（ = 0.003）。
在线龋病管理平台在提高口腔健康知识和行为（口腔卫生实践、糖消费行为和医疗行为）方面优于传统课堂讲授。该平台为口腔健康相关行为的发生和持续改善提供了可靠的实施路径。
