非创伤性技术充填乳牙两年的效果比较

A2-year clinic trial of atraumatic restorative treatmet in primary teeth

目的 :探索非创伤性充填 (ART)方法修复乳牙龋坏的效果。方法 :选取患牙本质龋的乳牙共 45 4颗 ,分为 3组 ,ART充填 15 4颗 ,15 1颗牙作为对照进行汞合金充填 ,14 9颗采用牙钻备洞 ,玻璃离子充填。 1年及2年后复查。结果 :大部分儿童使用ART治疗无不适感 ,93 .0 2 %的学生表示如果有龋坏牙 ,愿意使用同样的方法进行治疗。ART组第 1、2年的成功率 (84.7%、69.1% )与汞合金对照组 (77.1%、66.2 % )、牙钻玻璃离子组 (87.5 % ,74.9% )无显著性差异。使用玻璃离子材料的ART组及牙钻组两年继发龋发生率 (6.85 %、9.2 %与 6.3 5 %、8.62 % )低于汞合金对照组 (16.9%、2 1.5 % ) ,差异有显著性。结论 :ART技术简单易学 ,效果较好 。

objective: To study the effects of atraumatic restorative treatment(ART) in primary teeth. Methods: 154 primary teeth in 84 children were treated with ART, 149 in 83 with drill + glass ionomer filing and 151 in 81 with amalgam filing. 6～24 month follow up was conducted. Results: Most of the children did not report discomfort during ART treatment and 93.2% were willing to receive ART restorations again. 1 and 2 years after ART the success rate was 84.7% and 69.1%, after drill + glass ionomer restorations that was 87.5%, 74.9%, and after amalgam restorations that was 77.1%, 66.2%, respectively( P >0.05). Secondary caries were 6.85% and 9.20% in the group of ART, 6.35% and 8.62% in drill +glass ionomer restoration, 16.9% and 21.50% in amalgam restorations, respectively( P <0.01). Conclusion: The ART approach used for the treatment of primary tooth decay and for prevention of secondary caries is effective and acceptable.
