根管治疗法包括三大步骤:1.根管的扩大,清洗。2。根管消毒。3.根管充填。若其中任何一个环节处置不当,则降低治愈率或减慢治疗的速度。尤其是根管的扩大,清洗是根管治疗的基础。通过扩大,清洗才能将根管内的病变的,感染的硬和软组织彻底地清除,根管通畅也才能使药物,充填料确实地达到根尖和根尖周围组织。但是根管的解剖形态极为复杂,副根管,侧枝根又较多,呈交叉或网状。单纯的机械扩大,清洗法是难以达到目的。因而临床上常采用机械、化学方法并用。近年来使用的化学清洗剂不仅能
Root canal therapy includes three major steps: 1. Root canal expansion, cleaning. 2. Root canal disinfection. 3. Root canal filling. If any one of these links is not handled properly, reduce the cure rate or slow down the treatment. In particular, the expansion of the root canal, cleaning is the basis of root canal therapy. By expanding, cleaning in order to root canal lesions, infected with hard and soft tissue thoroughly removed, root canal patency in order to enable drugs, filling material to achieve the root tip and periapical tissue. However, the anatomy of the root canal is extremely complex, the root canal, lateral root and more, was cross or mesh. Purely mechanical expansion, cleaning method is difficult to achieve the goal. Therefore, clinically used mechanical, chemical methods and use. In recent years, the use of chemical cleaning agent not only
