摘要
目的:比较Trifecta热牙胶充填技术和冷牙胶侧方加压充填技术用于根管充填的治疗效果。方法:121例牙髓病、根尖周病患者随机分为2组。实验组68例共68颗患牙用Trifecta热牙胶充填技术进行根管充填,对照组53例共70颗患牙行冷牙胶侧方加压充填。观察术后疼痛发生情况、根充恰填率及成功率。结果:实验组的术后疼痛发生率明显低于对照组(实验组4.4%,对照组18.6%,P<0.01),两组术后疼痛指数差别无统计学意义;实验组的根充恰填率高于对照组(实验组89.7%,对照组77.1%,P<0.05);实验组的成功率明显高于对照组(实验组98.5%,对照组90.0%,P<0.05)。结论:Trifecta三维热牙胶充填技术较冷侧方加压充填技术能显著提高根管治疗的成功率,具有良好的根管三维充填效果。
Objective： To compare the therapeutic efficacy of the warm gutta-percha Trifecta technique and the cold later condensation technique. Methods： 121 patients were divided randomly into two groups. Experimental group used the warm gutta-percha Trifecta technique, while the control group used the cold lateral condensation technique. The symptoms and incidence of the postoperative pain, the proper filling rate and the success rate were observed. Results： In experimental group incidence of postoperative pain was significantly decreased and there were no differences on the pain symptoms in two groups. In experimental group proper filling rate and success rate were higher than those in the control group. Conclution： The warm gutta-percha Trifecta technique is better than the cold lateral condensation technique.
