It is generally accepted that non-surgical endodontic therapy eliminates periapical inflammation or infection and allows teeth to be restored that previously might have been extracted. However, failure does occur in a small percentage of cases. When confronted with such cases the clinician should be prepared to initiate alternative procedures, including surgery, to enhance the rate of success. This, the first of two articles, describes refinements in endodontic surgical techniques and introduces the research that has been used to develop new materials and devices.
一般认为，非手术牙髓治疗可消除根尖周炎症或感染，并使先前可能需要拔除的牙齿得以修复。然而，仍有一小部分病例会出现治疗失败。面对此类病例，临床医生应准备好启动包括手术在内的替代程序，以提高成功率。这是两篇文章中的第一篇，描述了牙髓外科技术的改进，并介绍了用于开发新材料和器械的研究。
