两种根管封闭剂临床应用效果分析

目的：观察两种根管封闭剂在根充中的临床效果。方法：随机抽取分别用于香油氧化锌糊剂和氯仿牙胶糊剂为根管封闭剂，根充后所摄的X线牙片各50例进行观察。结果：氯仿牙胶糊剂为根管封闭剂时，根适填率稍高于丁香油氧化锌糊剂。前超填率高，后欠填率大。结论：两种封闭剂均有较好的临床结果。

Analyses on the clinic curative effect of two endodontic sealers

Objective:To observe the clinic effect of two endodontic sealers in root filling treatment.Methods:100 dental films of teeth after root filling were randomly selected to observe their effects.Half of them were sealed by chloro-percha paste(CPP) while the other half were sealed by Zine Oxide eugenol paste(ZOE).Results:There was a slightly higher rate of proper-filling in CPP than that in ZOE.But it was easier to overfill in CPP,while in ZOE,the deficient-filling rate is higher.Conclusion:Effects of two sealers are good.
