Objective. The objective of this retrospective study is double: (1) to assess the 1-4 years of outcome of endodontic treatment performed by postgraduate students in endodontics in the Dental Clinic of Bretonneau Hospital and (2) to examine outcome predictors. Method. 363 teeth in 296 patients were treated between 2007 and 2011. 183 patients (224 teeth) were lost during the followup. 113 patients were included in the study (recall: 38%), corresponding to 139 teeth of which 8 were extracted. 131 remaining teeth (36%) were examined clinically and radiographically. Apical periodontitis (AP) was absent (PAI = 1) or present (PAI ≥ 2). Outcome was classified as "healed," "healing," or "diseased". Results. The success rate was 92%. No failure was observed among the 23 initial endodontic treatments. Among the 108 retreated teeth, 80% were "healed" and 11% were "healing." An association was found between success rate and preoperative signs or symptoms (absent 95% versus present 83%), preoperative root filling density (inadequate 93% versus adequate 57%), but not between preoperative AP status and success. Conclusion. Outcomes in this retrospective study were similar to those previously reported. However, a larger sample size is needed to assess outcome predictors more precisely.
目的。这项回顾性研究有双重目的：（1）评估布雷托诺医院牙科诊所牙髓病学研究生进行的牙髓治疗1至4年的治疗结果，以及（2）检查治疗结果的预测因素。方法。2007年至2011年期间，对296例患者的363颗牙齿进行了治疗。随访期间有183例患者（224颗牙齿）失访。113例患者（召回率：38%）纳入研究，对应139颗牙齿，其中8颗被拔除。对剩余的131颗牙齿（36%）进行了临床和影像学检查。根尖周炎（AP）不存在（PAI = 1）或存在（PAI≥2）。治疗结果分为“愈合”、“正在愈合”或“患病”。结果。成功率为92%。23例初始牙髓治疗中未观察到失败病例。在108颗再次治疗的牙齿中，80%“愈合”，11%“正在愈合”。发现成功率与术前体征或症状（不存在为95%，存在为83%）、术前根管充填密度（不充分为93%，充分为57%）之间存在关联，但术前AP状态与成功率之间无关联。结论。这项回顾性研究的结果与先前报道的结果相似。然而，需要更大的样本量来更精确地评估治疗结果的预测因素。
