Cortisomol糊剂充填根管的近期疗效

目的比较Cortisomol糊剂加牙胶尖、氧化锌丁香油糊剂加牙胶尖充填根管后反应和近期疗效.方法625个需进行根管治疗术的患牙随机分为4组;2组分别采用Cortisomol糊剂加牙胶尖(Cortisomol 1组)和氧化锌丁香油糊剂加牙胶尖(氧化锌1组)一次法充填根管.另2组经引流2 d 后分别用Cortisomol糊剂加牙胶尖(Cortisomol 2组)和氧化锌丁香油糊剂加牙胶尖(氧化锌2组)充填根管.观察术后1周内疼痛发生情况以及术后3个月、6个月疗效.结果Cortisomol 1组术后疼痛发生率较氧化锌1组低,Cortisomol 2组疼痛发率较氧化锌2组低,有显著性差异(P<0.05),Cortisomol 1组较Cortisomol 2组疼痛发生率高,无显著性差异(P>0.05),氧化锌1组疼痛发生率较氧化锌2组高,有显著性差异(P<0.05);术后3个月、6个月复查,Cortisomol糊剂组疗效高于氧化锌糊剂组,但无显著性差异(P>0.05). 结论Cortisomol糊剂充填根管可以有效减少一次法根管充填后疼痛发生,与氧化锌糊剂比较,近期疗效无明显差异.

Short period therapeutic effect of Cortisomol in root canal filling

AIM:To compare the occurrence of pain and the therapeutic effects of Cortisomol plus gutta percha and Zinc oxide eugenol paste plus gutta percha in root canal filling.METHODS:625 teeth were divided into 4 groups:Cortisomol sealer plus gutta-percha (Cortisomol 1) and Zinc oxide eugenol paste plus gutta percha (Zinc oxide 1) were used respectively in 2 groups of one time method; while Cortisomol sealer plus gutta-percha (Cortisomol 2) and Zinc oxide eugend paste plus gutta-percha (Zine oxide 2) were used in 2 days drainage in the other 2 groups. The occurrence of pain within 1 week after treatment was recorded and tle therapeutic effects were evaluated by follow up of 3 to 6 months.RESULTS:The occurrence rate of pain after root canal therapy using cortisomol 1 was lower than that of the group using Zine oxide 1 with significant difference (P<0.05);while,the occurrence of pain in the group using Cortisomol 2 was lower than tle group of using Zinc oxide 2 with significant difference (P<0.05).But rate of pain of Cortisomol 1 was higher than that of Cortisomot 2 without significant difference (P>0.05).Rate of pain of Zinc oxide 1 was higher than that of Zinc oxide 2 with significant difference (P<0.05). After 3 months and 6 months,efficiency rate of Cortisomol 1 and Cortisomol 2 were higher than that of Zine oxide 1 and Zine oxide 2 without significant difference (P>0.05).CONCLUSION:Root canal treatment applying Cortisomol sealer plus gutta-percha can decrease the rate of pain occurrence after root canal filling and the therapectic of Cortisomol sealer was not significant in short period.
