Abstract

This study assessed the influence of diverse variables on the outcome of nonsurgical root canal treatment/retreatment. In general, 304 teeth from 218 patients were treated/retreated and the outcome evaluated by the periapical index (PAI). Teeth with apical periodontitis lesions that have not completely healed were classified as success or failure based on lenient and rigid criteria, respectively. Findings were evaluated using a logistic regression analysis. The overall success rates were 74% and 82% using the PAI-rigid and lenient success criteria, respectively. Specifically for treatment, the success rates were 73% (rigid) and 82% (lenient), while for retreatment they were 78% (rigid) and 83% (lenient). The treatment outcome was negatively affected by overextension, presence of preoperative lesion, lesion size >10 mm, and higher number of treatment visits (with no intracanal medication). Regarding retreatment, the chance of success was greater for teeth with adequate coronal restorations.

影响非手术根管治疗和再治疗效果的因素：一项回顾性研究。

这项研究评估了各种变量对非手术根管治疗/再治疗结果的影响。总共对 218 名患者的 304 颗牙齿进行了治疗/再治疗，并通过根尖周指数（PAI）对治疗结果进行了评估。牙根尖牙周炎病变尚未完全愈合的牙齿根据宽松和严格标准分别被划分为成功和失败。研究结果通过逻辑回归分析进行评估。采用 PAI-严格和宽松成功标准的总体成功率分别为 74% 和 82%。具体到治疗，成功率分别为 73%（严格）和 82%（宽松），而再治疗的成功率分别为 78%（严格）和 83%（宽松）。过伸、术前存在病变、病变大小大于 10 毫米、治疗次数较多（未使用牙槽骨内药物）都会对治疗结果产生负面影响。关于再治疗，有足够冠状修复体的牙齿成功的几率更大。

期刊介绍： The Australian Endodontic Journal provides a forum for communication in the different fields that encompass endodontics for all specialists and dentists with an interest in the morphology, physiology, and pathology of the human tooth, in particular the dental pulp, root and peri-radicular tissues. The Journal features regular clinical updates, research reports and case reports from authors worldwide, and also publishes meeting abstracts, society news and historical endodontic glimpses. The Australian Endodontic Journal is a publication for dentists in general and specialist practice devoted solely to endodontics. It aims to promote communication in the different fields that encompass endodontics for those dentists who have a special interest in endodontics.
