本研究对144例患者的190颗根管治疗牙进行了10年生存率的回顾性研究。在1987年和1988年的培训期间，学生们进行了治疗。年龄、性别、下颌、根管数量对根管治疗的成功没有影响。在根管治疗前有根尖病变的牙齿存活的可能性明显较短。根管充填在根尖前0 ~ 1mm和1 ~ 2mm处效果最好。比较修复的类型，假体治疗的牙齿保留桩和冠似乎是有利的。研究表明，即使由学生进行根管治疗，10年后的生存率为85.1% (Kaplan-Meier)，是一种持久的保守治疗。
In this retrospective study the survival rate of 190 root-canal-treated teeth of 144 patients after 10-yr minimum was evaluated. Students during their training in 1987 and 1988 had performed the treatments. Age, gender, jaw, or quantity of root canals had no influence to the success of a root-canal treatment. Teeth with an apical lesion before the endodontic treatment showed a significantly shorter likelihood of survival. The best results could be found in root-canal fillings ending 0 to 1 mm and 1 to 2 mm before the apex. Comparing types of restoration, prosthetic-treated teeth with retention post and crown seem to be favorable. The study showed that root-canal treatment even conducted by students has a survival rate of 85.1% (Kaplan-Meier) after 10 yr and is a long-lasting, conservative therapy.
