迄今为止,对急性根尖脓肿的病例,一般被认为是一次根管治疗的禁忌症。本文目的旨在评价一次根管活疗急性根尖脓肿的疗效。病例来源于芝加哥大学牙科急诊的19位病人。这些病人均被诊断为根尖脓肿(粘膜下脓肿)。只选择单根管或双根管的患牙。通过X 线片和临床试验确定患可。采用阻滞麻醉以免注射针通过或进入脓肿区。用外科手术刀切开脓肿下份,切口长约1～1.5cm,以刮匙或止血钳插入切口以便贯通脓肿的各个部分。之后,置入无菌橡皮烟式引流条。置橡皮障以隔离患牙,暴露常规根管进路。常用5.25%次氯酸钠冲洗至根管制备完成。然后用无菌纸尖吸干,用粗于根管的标准牙胶尖蘸氯仿充填至根尖1mm 内,抽出后再蘸封闭剂(kerr sealer)换入根管,加热垂直加压充填。洞口用暂时充填材料密封,
To date, cases of acute apical abscess are generally considered to be a contraindication to endodontic treatment. The purpose of this article is to evaluate the efficacy of primary root canal therapy of acute apical abscess. The cases were from 19 patients at the University of Chicago dental emergency. These patients were diagnosed as apical abscess (submucosal abscess). Only choose a single root canal or double root canal teeth. By X-ray film and clinical trials to identify patients. Block anesthesia in order to avoid injection needle or enter the abscess area. With surgical scalpel incision under the abscess, incision length of about 1 ~ 1.5cm, with a curette or hemostat inserted into the incision in order to penetrate the abscess of the various parts. After that, put a sterile rubber smoke-type drainage rod. Set the rubber dam to isolate the affected tooth and expose the conventional root canal approach. Commonly used 5.25% sodium hypochlorite rinse to the root canal preparation is completed. Then use a sterile tip of the paper to dry, with a thick root of the standard toothpaste dipped in chloroform into the apical root tip 1mm, and then dipped blocking agent (kerr sealer) into the root canal, heated vertical pressure filling. Hole with a temporary filling material sealed,
