An oral health care programme in secondary schools using the atraumatic restorative treatment (ART) technique for dental caries was started in 1993. Glass-ionomer was used as the restorative and sealant material. Sealants were placed using the "press finger' technique. Results after 1 year revealed a survival percentage for one-surface ART restorations of 93.4 whilst the complete and partial retention percentages for sealants were 60.3 and 13.4, respectively. No caries was observed in teeth restored using ART, and only 0.8% of surfaces diagnosed as having early enamel lesions at the start of the programme and sealed consequently had progressed into active dentinal lesions after 1 year. The sealant retention percentage and the survival percentage of ART restorations were influenced by an operator effect. The majority of restorations were carried out without administering local anaesthesia. The mean treatment time for one-surface ART restorations was 22.1 min (range per operator of 19.8-23.6 min), whilst the mean time for placing sealants was 9.4 min (range per operator of 8.2-10.8 min). Post-operative sensitivity was reported for 6% of the teeth restored. 95% of the students were satisfied with ART as a treatment modality. It is concluded that ART may in part be the answer to the unavailability of restorative care for many population groups globally.
1993年，一项在中学开展的口腔保健项目启动，该项目采用非创伤性修复治疗（ART）技术治疗龋齿。玻璃离子用作修复和封闭材料。使用“按压手指”技术放置封闭剂。1年后的结果显示，单面ART修复体的存留率为93.4%，而封闭剂的完全和部分保留率分别为60.3%和13.4%。使用ART修复的牙齿未观察到龋齿，在项目开始时被诊断为早期釉质病变并因此进行封闭的表面，1年后仅有0.8%进展为活动性牙本质病变。ART修复体的封闭剂保留率和存留率受操作者效应影响。大多数修复操作未使用局部麻醉。单面ART修复体的平均治疗时间为22.1分钟（每位操作者的范围为19.8 - 23.6分钟），而放置封闭剂的平均时间为9.4分钟（每位操作者的范围为8.2 - 10.8分钟）。据报告，6%接受修复的牙齿有术后敏感症状。95%的学生对ART作为一种治疗方式感到满意。结论是，ART可能部分解决了全球许多人群无法获得修复治疗的问题。
