龋病在我国儿童中发病率极高，而充填率低。为了适应发展中国家的口腔治疗需要，ＷＨＯ提倡的非创伤性充填治疗（ＡＲＴ）技术，用简单手用器械及改进的玻璃离子材料作为充填材料。不再需要昂贵的设备，高水平的医生。但以往的研究多是恒牙。目的：为了探索ＡＲＴ修复乳牙龋坏的效果，为了比较手用器械与机钻的疗效进行了本研究。方法：该研究在四川省成都市地区选取３个学校由受过三年训练的中专口腔医生采用该技术对乳牙龋坏进行充填，在一个月内对１２４名６～８岁儿童作了２１１个充填，其中１４７颗牙为试验组用手用器械，另６４颗牙用机钻作对照组。半年以后复查。结果：试验组成功率为８９．８％，对照组９０．６％，差异无显著性。结论：对发展中的中国，ＡＲＴ不失为一种有前途的龋病充填治疗方法，是可以在农村及中小城镇广泛采用的有前景的防治措施。
Caries in children in our country a very high incidence, while the filling rate is low. In response to the need for dental treatment in developing countries, WHO advocates non-invasive ART techniques using simple hand instruments and improved glass ionomer materials as filling material. No longer need expensive equipment, high-level doctors. But the past research is mostly permanent teeth. OBJECTIVE: To explore the effect of ART in deciduous deciduous teeth caries, this study was conducted to compare the efficacy of hand instruments and machine-drilling. Methods: The study selected three schools in Chengdu, Sichuan Province. Three-year-old secondary dental school doctors used this technique to fill deciduous deciduous teeth. A total of 211 children aged 6-8 years Filling, of which 147 teeth for the test group with hand instruments, and the other 64 teeth machine control group. Review after six months. Results: The success rate of the experimental group was 89.8% and that of the control group was 90.6%, with no significant difference. Conclusion: ART is a promising method for dental caries filling in developing China and is a promising preventive and control measure that can be widely used in rural areas and small towns.
