为了确定在根管治疗过程中是否需要开放治疗以及开放引流的次数,作者对5000例根管治疗的病例进行了分析。本文所有病例的治疗方法如下:第一次就诊时清洗根管以次氯酸盐溶液冲洗根管。初诊前根管已开放的牙齿行根管清洗后仍保持开放,一周后复诊时即可封闭根管,如果牙齿在封闭后再发生疼病或肿胀,应再开放一周重新封闭或封闭后作牙槽骨壁钻孔引流或根尖切除。对伴有发热或出现肿胀而又引流不畅的急性牙槽脓肿者给予抗菌素。如果 To determine whether open treatment and open drainage are required during root canal therapy, the authors analyzed 5000 cases of endodontic treatment. The treatment of all cases in this article is as follows: Wash root canal on first visit Flush root canal with hypochlorite solution. Before the first visit, the root canal has been opened. The root canal is still open after root canal cleaning. The root canal can be closed after the first visit. If the tooth is closed again and then the pain or swelling occurs, it should be reopened for a week or closed again Slot drilling drainage or apical resection. Antibiotics were given to acute alveolar abscess associated with fever or swelling and poor drainage. in case
