三种根管充填材料对疼痛发生情况的比较

Comparison of the Occurrence of Pain After Root Canal Filling with Three Different Materials

目的:比较三种根充糊剂充填根管后的疼痛发生情况。方法:278颗需要进行根管治疗的患牙分为活髓牙A组及死髓牙B组,A,B两组又分为A1、A2、A3及B1、B2、B3三个亚组,A组分别用Cortisomol糊剂+牙胶尖(A1),氧化锌丁香油糊剂+牙胶尖(A2),氧化锌丁香油糊剂+地塞米松+牙胶尖(A3)进行一次性根管充填;B组使用与A组相同材料进行常规治疗,暂封3-5 d后根管充填,观察术后2周内的疼痛出现情况。结果:在活髓牙组(A)中Cortisomol糊剂+牙胶尖(A1)同氧化锌丁香油糊剂+地塞米松+牙胶尖(A3)的疼痛发生率无显著性差异(P>0.05),而Cortisomol糊剂+牙胶尖(A1)与氧化锌丁香油糊剂+地塞米松+牙胶尖(A3)的疼痛发生率均显小于氧化锌丁香油糊剂+牙胶尖(P<0.05),在死髓牙组(B)中观察到同样的结果,即B1与B3间疼痛发生率无显著性差异(P>0.05),但均显著的小于B2的疼痛发生率(P<0.05)。结论:传统的根管充填糊剂中加入少量的地塞米松可减少根管治疗后疼痛,其效果等同于价格昂贵的Cortisomol糊剂。

Objective： To compare the occurrences of pain after root canal filling with three different kinds of materials. Methods： A total of 278 teeth for root canal treatment were divided into vital group （group A） and non-vital teeth （group B）. Each group was divided into three sub-groups according to different filling materials as Cortisomol sealer＋gutta-percha （A1 and B1）, Eugenol （ZOE） ＋gutta-percha （A2 and B2） and ZOE＋dexamethasone＋gutta-percha （A3 and B3） group respectively. Results： No significant difference between the occurrence rate of pain in A1 and in A3 （P〉0.05）, but both occurrence rates in A1 and A3 were lower than in A2 with significant difference （P〈0.05）. In B group, there was no significant difference between B1 and B3 （P〉 0.05）, but the occurrence rate of pain in B1 and B3 was lower than in B2 with significant difference （P〈0.05）. Conclusion： The material of ZOE＋gutta-percha＋dexamethasone that is cheaper than Cortosomal sealer and can also decrease the rate of pain occurrence after canal filling.
