目的 :比较Vitapex糊剂单独使用及与牙胶尖联合使用充填根管后的临床疗效。方法 :A组单独使用Vitapex糊剂 ,B组使用Vitapex糊剂加牙胶尖 ,C组使用传统氧化锌丁香油糊剂加牙胶尖进行根充 ,与治疗前及随访 1年后拍摄根尖周片对比。结果 :三组成功率分别为 96 .70 %、98.90 %、89.0 1%。其中A、B组无显著差异 (P >0 .0 5 ) ,A、C组与B、C组差异均显著 (P <0 .0 5 )。结论 :Vitapex糊剂是一种新型、简便的根充材料 ,单独或与牙胶尖联合使用均能起到较好的疗效 。

AIM:To compare the clinical effect of treatment of chronic apical periodontitis with vitapex paste alone or combined with gutta-percha. METHODS: 212 patients with 273 infected teeth were randomly divided into three groups. Group A were treated with vitapex paste alone. Group B were treated with vitapex paste plus gutta-percha. Group C were treated with traditional zinic exide olive oil paste plus gutta-percha. Periapical radiograph was taken before and after 1 year. RESULTS: After one year, success rates of three groups were 96.70%, 98.90%, 89.01% respectively. Difference between Group A and C, Group B and C were significant( P <0.05). CONCLUSION: The vitapex paste is a new and simple filling material and shows better clinical treatment effect using alone or combined with gutta-percha. It is suitable for widespread adoption in root canal treatment.
