Cortisomol根管糊剂根充术后反应临床观察.docVIP

Cortisomol根管糊剂根充术后反应临床观察[摘要]目的:观察Cortisomol根管糊剂根充术后反应并与临床最常用的氧化锌丁香油酚糊剂(ZOE)相比较。方法:门诊就诊的根充术适应证患者180例随机分为实验组(Cortisomol组)112例(126颗)和对照组(ZOE组)68例(72颗)。常规根管预备、根管消毒后,分别用Cortisomol糊剂和氧化锌丁香油酚糊剂进行根管充填术,观察术后的反应。结果:实验组治疗后31.7%患牙未出现疼痛,累计80.2%患牙2天内完全止痛,累计97.6%患牙4天内完全止痛;对照组治疗后12.5%患牙未出现疼痛,累计43.1%患牙2天内完全止痛,累计80.6%患牙4天内完全止痛。根充后疼痛发生率和持续时间实验组明显低于对照组。结论:Cortisomol是一种较为理想的根管充填剂。 [关键词]Cortisomol;根管充填材料;根管治疗术 [中图分类号]R783 [文献标识码]A [文章编号]1008-6455(2010)01-0102-02 Observation of root canal filling with Cortisomol CHANG Shi-min,ZHANG Fang-ming (Department of Stomatology,Beijing Friendship Hospital affiliate to Capital Medical University,Beijing 100050,China) Abstract:Objective To observe the curative effects of root canal therapy with two kinds of materias,cortisomol and ZOE.MethodsThe experiment group (Cortisomol group) including 126 teeth of 112 patients and the control group(ZOE group)including 72 teeth of 68 patients were assigned randomly. After general canal preparation, the experiment group was filled with Cortisomal and the control group was filled with ZOE. Results In 31.7% of the teeth of experiment group, pain did not appear.About 80.2% of the teeth of experiment group thoroughly ceased aching within two days, and 97.6% within four days. The occurence rate of pain in the experiment group was lower than that of the control group. The time of pain in the experiment group was shorter than that of the control group.ConclusionThe Cortisomol is a relatively ideal material for root canal therapy.
