三种根管糊剂用于一次性根管治疗术后的评价

目的：对AH Plus，Vitapex及Cortisomol糊剂在一次性根管治疗术后，对疼痛及远期疗效评价。方法：180颗患牙随机分为三组，分别以AH Plus,Vitapex和Cortisomol糊剂配合牙胶尖充填根管，对术后1周、3、6、12个月的疼痛及远期疗效进行评估。结果：术后1周随访，AH Plus、Cortisomol糊剂与Vitapex疼痛发生率有显著性差异，前两者之间无显著性差异；经3、6、12个月复查，在根尖周炎病例的治疗中，Vitapex与AH Plus和Cortisomol糊剂远期愈合率有显著性差异，后两者之间无显著性差异。结论：AH Plus和Cortisomol糊剂对一次性根管治疗术后疼痛的缓解有较好的效果，而Vitapex糊剂在促进根尖周组织的愈合方面，更具有优越性。

The postoperative pain relief and long-time outcome of three root filling pastes after one-visit root canal ther- apy.

Objective：The purpose of this study was to compare the postoperative pain relief and long-time outcome of AH Plus, Vitapex,and Cortisomol pastes after one-visit root canal therapy. Method： A total of 180 selected teeth were randomly allocated into the three paste groups. The pain intensity was recorded according to the response evaluation stan- dard one week after treatment. The long-time outcome was recorded according to the curative effect evaluation standard 3, 6 and 12 months after treatment. Result： （1）The difference of pain intensity between AH Plus and Cortisomol paste group was not significant, while the pain intensity in Vitapex paste group was significantly different from the former two groups （P 〈 0.05）. （2）The long-time outcome in the three groups showed no statistical difference. The Vitapex paste group showed better effect in periapical periodontitis cases than the other two groups （P 〈0.05）. Conelution. The AH Plus and Cortisomol paste are more effective to release the postoperative pain. However, Vitapex paste showed better effect in periapical periodontitis cases.
