摘要 目的评价Metapex糊剂2种封药方法用于磨牙感染根管治疗的临床效果。方法慢性根尖周炎或牙髓坏死的下颌第一磨牙患者68例68颗患牙按就诊顺序随机分为2组。首诊时开髓、清洗,髓腔封Metapex糊剂;再诊时根管预备后封药。试验组选择小于根管预备完成锉锥度和号数的牙胶尖,将Metapex糊剂重复导入并蘸糊剂插入根管内封药;对照组注入式填充Metapex糊剂封药。观察2种方法封药的根管消毒效果。结果封Metapex糊剂1周后,试验组有效率为85.3%,对照组为79.4%,2组无重度疼痛发生。2组的临床疗效、疼痛发生率、疼痛和不适及持续时间差异无统计学意义。结论根管预备后牙胶尖蘸Metapex糊剂封药方法,使用方便,消毒效果可靠,具有临床可行性。
