有瘘型慢性根尖周炎Vitapex根管封药的临床观察

Clinical observation of vitapex paste as root canal medicaments against chronic apical periodontitis

目的观察对比Vitapex糊剂和樟脑酚的根管封药效果。方法218颗有瘘型慢性根尖周炎的患牙经过根管预备后分为实验组（Vitapex糊剂封药组）和对照组（樟脑酚封药组），对封药后患牙疗效及对根管治疗期间急症疼痛的发生率进行比较。结果实验组有效率97．25％，对照组有效率89．91％，两组疗效有显著性差异垆〈0．05）实验组和对照组急症疼痛发生率分别为4．59％,16．51％，两组比较有显著性差异（P〈0．05）。结论Vitapex糊剂根管内封药能有效控制感染和预防根管治疗期间疼痛的发生。

Objective To compare the clinical effect of Vitapex paste （calcium hydroxide based paste） and Camphorated Para-monochlorophenol （ CP ） when used as root canal medicaments. Method 218 patients with chronic apical periodontitis were randomly divided into Vitapex paste group as experimental group and the CP group as control group. The therapeutic effect and incidence rate of endodontic interappointment pain（ EIP ）between them were compared after filled as root canal medicaments. Result The effective ratio of Vitapex paste group and CP group were 97.25% and 89.91%, respectively. The incidence of EIP of Vitapex paste group and CP group were 4.59% and 16. 51%, respectively. The difference between them was statistically significant （chi-square, P 〈 0.01）. Conclusion This study showed that Vitapex paste can prevent the infection and incidence of EIP in the root canal of chronic apical periodontitis efficiently better than CP.
