• 摘要：目的 利用自主研发的AI智能便携式数智设备，筛查重庆偏远山区小学生的口腔健康状况，评估该地区儿童龋病流行现状，探讨儿童口腔健康与筛查策略。方法 整群抽取重庆市丰都县仙女湖镇中心小学106名7~13岁在读儿童作为研究对象。使用AI便携设备对受试儿童进行全面的口腔健康检查。报告患龋率、患龋颗数、患龋牙面数，计算国际龋病检测和评估系统II（ICDAS II）、龋失补指数（dmft）、菌斑指数（PLI）得分，进行牙面和牙位分组分析。结果 该小学总体患龋率为93.40%，PLI得分为2.30±0.64，dmft为6.45±4.38，牙面、牙位患成洞龋的比例均高于早期龋，牙颌面的患龋率最高。低龄儿童(7~9岁)的dmft显著高于高龄组(10~13岁)(P=0.002)。结论 重庆市偏远山区学龄儿童患龋率极高，口腔健康状况极其严峻，应使用AI便携设备扩大筛查范围，加强筛查频率，做好低龄儿童龋病防治工作。

  Abstract: Objective To use a self-developed AI intelligent portable digital device to screen the oral health status of primary school students in remote mountainous areas of Chongqing, assess the prevalence of dental caries among children in the region, and explore childrens oral health and screening strategies. Methods A total of 106 children aged 7-13 from the Xianren Lake Central Primary School in Fengdu County, Chongqing, were selected as study subjects through cluster sampling. The AI portable device was used to conduct a comprehensive oral health examination of the participants. The prevalence of caries, number of decayed teeth, and number of affected tooth surfaces were reported; International Caries Detection and Assessment System Ⅱ (ICDAS Ⅱ), decayed, missing and filled teeth (dmft), and Plaque index (PLI) scores were calculated; and tooth surface and tooth position subgroup analyses was conducted. Results The overall caries prevalence rate in the school was 93.40%. The PLI score was 2.30 ± 0.64, and the dmft index was 6.45±4.38. The proportion of cavitated caries was higher than that of early-stage caries in both tooth surfaces and tooth positions, with the occlusal surfaces having the highest caries prevalence. The dmft index was significantly higher in younger children (7–9 years) compared to older children (10–13 years) (P = 0.002). Conclusion The caries prevalence rate among school-aged children in remote mountainous areas of Chongqing is extremely high, indicating a severe oral health status. AI-powered portable devices should be utilized to expand the scope of screening, increase screening frequency, and enhance caries prevention and treatment efforts for younger children.
