三种根管充填糊剂对根管充填后疼痛反应的影响

目的观察氧化锌丁香油糊剂、氧化锌丁香油 碘仿糊剂、Cortisomo(l碧兰糊剂)充填根管后患者对疼痛的反应。方法选取在门诊行根管治疗的患者65例(患牙87颗),随机分成3组:A组使用氧化锌丁香油糊剂 牙胶尖充填;B组使用氧化锌丁香油 碘仿糊剂 牙胶尖充填;C组使用碧兰糊剂 牙胶尖行根管充填。随诊观察术后的疼痛反应情况。结果根充后疼痛的发生率C组低于B组,B组低于A组;C组与A、B组均有显著性差异(<0.05),但A组与B组的疼痛发生率无显著性差异(<0.05)。结论碧兰糊剂是一种理想的根管充填糊剂。

Influence on the Pain Occurrence After Root Canal Filling with Three Kinds of Materials

Objective To observe the pain occurrence after root canal filling with three different kinds of materials.Methods 87 teeth for root canal treatment were divided into group A,group B and group C randomly. Group A was filled with Eugenol(ZOE) gutta-percha,group B was filled with Eugenol(ZOE) indoform gutta- percha and group C was filled with Cortisomol sealer gutta-percha.Results In group A the rate of painlessness, moderate pain and severe pain was 33.33%,53.33%and 13.33%respectively,in group B it was 44.83%,44.83% and 10.34%respectively,while in group C it was 71.43%,25%and 3.58%respectively.There was no significant difference between the occurrence rate of pain in group A and group B,but significant difference was found be- tween the occurrence rate of pain in group C and group A,group B.Conclusion Cortisomol sealer is an ideal material for root canal filling.
