In Part I which appeared two issues previously, the authors discussed the variations in treatment methods of nonsurgical endodontic therapy and in the determination of success and failure. They then reported on the materials and methods used and the radiographic criteria for success and failure in their clinical study of 458 root canals treated by the gutta-percha-eucapercha method. In Part II which appeared in the last issue, the one-year follow-up results were presented. Some of these results differ from previous investigations. For example, better success was found in (1) necrotic cases with areas of pathosis than in necrotic cases without "areas and in (2) overfilled cases than in underfilled cases. In Part III the authors discuss the possible reasons for these and other findings and give some implications for clinical practice.
在前两期发表的第一部分中，作者讨论了非手术牙髓治疗方法的差异以及成功与失败的判定标准。然后，他们报告了在一项对458颗采用牙胶-桉叶油牙胶法治疗的根管进行的临床研究中所使用的材料和方法，以及成功与失败的影像学标准。在上一期发表的第二部分中，呈现了一年的随访结果。其中一些结果与之前的研究不同。例如，发现（1）有病变区域的坏死病例比无病变区域的坏死病例成功率更高，以及（2）超充病例比欠充病例成功率更高。在第三部分中，作者讨论了这些及其他研究结果的可能原因，并给出了对临床实践的一些启示。
