Microbe infection is not only the key pathogenic factor of primary endodontic infectious diseases, but also the arch-crimina of endodontic treatment fail. Therefore, the endodontic treatment success is based on the debridement of infectious root canal, elimination of bacteria, and the prevention of endodontic reinfection. It is beset with difficulties to control the endodontic infection in clinic because of the bacterial variety, anatomic complexity of root canal, and limitation of the root canal therapeutic methods. In order to get the ideal prognosis of the root canal treatment, in the procedure of the therapy, it should be the tight isolation of tooth, reasonable choose of the root canal preparation technique, rational use of root canal preparation instrument, effective irrigation of root canal, proper root canal dressing, and the 3-dimensional obturation of root canal.
微生物感染不仅是原发性牙髓感染性疾病的关键致病因素，也是牙髓治疗失败的罪魁祸首。因此，牙髓治疗的成功基于感染根管的清创、细菌的清除以及牙髓再感染的预防。由于细菌种类繁多、根管解剖结构复杂以及根管治疗方法的局限性，临床上控制牙髓感染困难重重。为了获得根管治疗的理想预后，在治疗过程中，应严格隔离患牙，合理选择根管预备技术，合理使用根管预备器械，有效冲洗根管，适当进行根管封药，以及对根管进行三维充填。
