非创伤性充填龋坏乳牙效果观察

A Two-year Clinical Trial of Atraumatic Restorative Treatment in Primary Teeth

目的 :探讨非创伤性充填技术 (ART)修复乳牙龋的效果及儿童对ART的接受程度。方法 :选取患牙本质龋的乳牙共 30 5颗 ,试验组采用强度较高的玻璃离子 (dentsply)完成ART充填 15 4颗牙 ;对照组采用汞合金充填 15 1颗牙。治疗后半年、1年、2年各复查 1次。结果 :①试验组大部分患儿治疗中无不适感 ,93 0 2 %的患儿表示如果有龋坏牙愿意使用同样的方法治疗。②试验组两年的成功率 (84 7%、6 9 1% )与对照组 (77 2 %、6 6 3% )相比无显著性差异。③试验组两年的继发龋发生率 (6 85 %、9 2 % )低于对照组 (16 9%、2 1 5 % ) ,差异有显著性 (P <0 0 5 )。结论 :ART技术简单易学 ,对乳牙龋是一种有效的治疗方法。

Objective:The purpose of this clinical trial was to investigate the effects of atraumatic restorative treatment (ART) under field conditions, compare it to another treatment with amalgam, and survey the acceptability of this approach by patients.Methods:154 teeth were treated using ART, while other 151 teeth were treated using amalgam, and the therapeutic effects of each patient was evaluated after half of year, 1 year and 2 years.Results:Most of the children did not report discomfort during treatment, and 93 2% would like to select ART rather than other treatments. The one_year and two_year success rates of ART were 84 7% and 69 1%. Comparing with those of amalgam restorations (77 2% and 67 2%), there was no statistical difference (P>0 05). However, the two_year recurrent rate of secondary caries treated with ART approach (9 2%) was obviously lower than that with amalgam treatment (21 5%)(P<0 05).Conclusion:ART may be an appropriate and effective method for the treatment of primary teeth.\;
