摘　　要：目的评价GuttaFlow2垂直加压充填根管桩道预备前后在单根管离体牙中的根尖封闭性。方法选取100颗离体牙随机分为8组。A1、A2组:GuttaFlow2垂直加压充填(n=15);B1、B2组:热牙胶连续波垂直加压充填(n=15);C1、C2组:冷牙胶侧方加压充填(n=15);D组为阳性对照(n=5);E组为阴性对照(n=5),A1、B1、C1组不进行桩道预备,A2、B2、C2组进行桩道预备。采用透明牙技术评价桩道预备前后根尖封闭情况。结果不进行桩道预备,A1、B1、C1三组间比较差异均有显著性(P<0.05);进行桩道预备,A2、B2、C2三组间比较差异均有显著性(P<0.05);相同充填方法的各组间,A1、A2比较,差异无统计学意义(P>0.05),B1与B2、C1与C2比较,差异有统计学意义(P<0.05)。结论GuttaFlow2垂直加压充填的根尖封闭性优于热牙胶连续波垂直加压充填和冷牙胶侧方加压充填,GuttaFlow2垂直加压充填桩道预备前后的根尖封闭性差异无统计学意义,GuttaFlow2垂直加压充填具有良好的根管充填效果。Objective To evaluate the apical sealing ability before and after post space preparation with GuttaFlow2 vertical conden⁃sation obturation in isolated teeth with single canal.Methods One hundred isolated teeth were selected and randomly divided into 8 groups.Group A1 and A2:GuttaFlow2 vertical condensation obturation(n=15);Groups B1 and B2:continuous wave of vertical con⁃densation obturation(n=15);Group C1 and C2:cold lateral condensation obturation(n=15);Group D:the positive controls(n=5);Group E:the negative controls(n=5).Post space was not prepared in groups A1,B1 and C1,but prepared in groups A2,B2 and C2.The apical sealing before and after post space preparation was evaluated by transparent dental technology.Results Without post space preparation,the differences between A1,B1 and C1 three groups were all significant(P<0.05).With post space prepara⁃tion,the differences between A2,B2 and C2 three groups were significant(P<0.05).Among groups with the same filling method,there was no statistically significant difference between A1 and A2(P>0.05),but there was statistically significant difference between B1 and B2,C1 and C2(P<0.05).Conclusion The apical sealing ability of GuttaFlow2 vertical condensation obturation is better than the continuous wave of vertical condensation obturation and the cold lateral condensation obturation.There is no difference in apical sealing ability before and after post space preparation with GuttaFlow2 vertical condensation obturation.GuttaFlow2 vertical condensation obturation has good root canal obturation effect.
