| 摘 要： | 目的比较MTA糊剂、Vitapex糊剂、氧化锌丁香油糊剂根充后对根管侧壁和根尖区的微渗漏情况,评价MTA糊剂的封闭性能。方法收集离体牙常规根管预备后随机分为三组,分别使用三种糊剂充填后染色,按一定时间取出,片切,并测量染液渗入根管侧壁和根尖孔的长度。结果 MTA组染液渗入根管侧壁和根尖孔的长度数值于1周、2周、4周时均少于Vitapex组和氧化锌丁香油组（P〈0.05）。结论 MTA糊剂的根管封闭性均优于Vitapex糊剂和氧化锌丁香油糊剂,有望作为新的根管封闭剂使用。

| Abstract: | Objective To compare the effect of MTA paste, Vitapex paste and zinc oxide-eugenol paste on apical microleakage after root canal filling, and evaluate the sealing ability of the MTA paste. Methods Extracted teeth were randomly divided into three groups (group A, group B, group C) after treated with routine root canal preparation technique, each with 30 cases. The teeth in the three groups were filled with MTA paste, Vitapex paste and zinc oxide-eugenol paste, respectively, and then dyed and sliced to measur... |
