摘　　要：目的：评价Vitapex治疗成年患者根尖闭合不全伴慢性根尖周炎或牙髓坏死患牙的效果。方法选择成年患者根尖闭合不全患牙44颗，其中26颗前牙，18颗前磨牙，所有患牙随机分为试验组和对照组，其中试验组22颗，对照组22颗，所有患牙常规根管预备消毒后，试验组使用Vitapex糊剂进行根尖诱导成形，对照组使用氢氧化钙糊剂，均在根尖部有硬组织形成后行根管充填。两组均定期复查，观察临床症状及拍摄X线片。结果经过6个月～2年随访，27颗患牙获得根尖闭合，其中试验组17颗，成功率77．3％，对照组10颗，成功率45．5％，两组差异有统计学意义（ P＜0．05）。结论 Vitapex治疗成年患者根尖闭合不全的患牙有良好的疗效。Objective To evaluate the clinical effects of Vitapex to treat the open apices teeth with chronic apical pe-riodontitis or pulp necrosis in adult patients.Methods A total of 44 teeth were collected, including 28 anterior teeth and 16 premolars.The teeth were divided into 2 groups randomly, with 22 cases each in experimental group and control group respectively.The root canal of all cases were prepared and sterilized, then Vitapex was applied to experimental groups while calcium hydroxide paste was applied to control group.All the root canals were filled when the apical barrier could be detected.The cases were recalled regularly, and given the clinical and radiographic evaluation.Results The apical barrier were attained in 27 cases after a 6 month ~2 years recall, and 17 cases among which were observed in ex-perimental group, with an efficacy rate of 77.3%, while the other 10 cases were in control group, with an efficacy rate of 45.5%.There was a significant difference between the 2 groups （P〈0.05）.Conclusion Vitapex has good effects to treat teeth with open apices in adult patients.
