124名一年级小学生乳牙龋坏充填半年观察报告

THE OBSERVATION OF PRIMARY TOOTH RESTERATION HALF A YEAR AFTER PLACEMENT TO 124 GRADE ONE STUDENTS IN PRIMARY SCHOOL.

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。

Dental caries prevalence is very high in our country,but the filled component is very low.WHO advocates a new treatment Atraumatic Restorative Treatment in 1994.The technique is based on removing decalcified tooth tissue using only hand instrument and restoring the cavity with an adhesive filling material.The technique does not require expensive equipment and electricity.Objective:This study compares the ART technique to conventional amalgam restoration in the management of dental caries.Methods:This trial was carried out to 124 children in three primary school.ART treated 147 restoration in trial group while 64 restorations were used by conventional amalgam in contrast group.Clinical evaluation was carried out half a year after placement.Results:The survival rate of ART restoration(89 8%) was closed to those for amalgam restoration(90 6%).Conclusions:ART technique is a feasible approach for the treatment of dental caries,which can make the control of dental caries available to all people irrespective of their economic and living condition.
