所有根管治疗的牙齿，提取超过1年的时间在一个忙碌组的做法进行了评估失败的原因。 收集的116颗牙齿分为修复，牙周和牙髓起源的主要失败类别。 在这些牙齿中，59.4%是修复失败，主要是由于牙冠断裂。 有牙冠的牙齿比没有牙冠的牙齿寿命更长。 定期失败占研究的32%。 只有8.6%的失败是由于根管原因，但这些失败变得更明显比其他类别。 故障的分类，并分析了结果。
All endodontically treated teeth that were extracted over a 1-yr period in a busy group practice were evaluated for cause of failure. The 116 teeth collected were classified into major failure categories of prosthetic, periodontic, and endodontic origin. Of the teeth, 59.4% were prosthetic failures which were due primarily to crown fracture. Teeth that had been crowned had greater longevity than uncrowned teeth. Periodontal failures constituted 32% of the study. Only 8.6% of the failures were due to endodontic causes, but these failures became evident more quickly than those in the other categories. A classification of failures is presented, and the results are analyzed.
