摘要： 目的评价AHplus和GuttaFlow根管封闭剂的根尖和冠方长期封闭性能。方法收集人离体恒前牙80颗，根面处理后用手用镍钛锉预备后随机分为4个实验组即为：AHplus+牙胶尖侧压根管充填，7 d后（A组）、90 d后（C组）观察；以Guttaflow+主尖根管充填，7 d后（B组）、90 d后（D组）观察（每组20颗）。根充后用印度墨汁染色、脱矿、脱水、制成透明，在体视显微镜下测量染料从冠方和根尖渗入根管的长度。结果 4组根尖部的染料渗入长度为（0.67±0.67）、(0.51±0.76)、（3.07±1.09）、（2.10±0.59）mm，冠部微渗漏为（0.42±0.46）、（0.53±0.46）、（2.62±0.98）、（2.41±0.68）mm，A组与其他3组根尖部和冠部的染料渗入长度差异有统计学意义。结论 GuttaFlow+单尖法短期和长期冠部和根尖的封闭性很好，优于AHplus封闭剂。

Abstract: Objective To compare the apical and coronal sealing ability of three kinds of root canal filling materials. Methods 80 single rooted human anterior teeth were prepared and divided into four experimental groups(n=20) to evaluate the leakage 7 days and 90 days later. Group A and C used lateral compaction guttapercha with AHplus. Group B and D were filled with GuttaFlow+single cone. Results The apical leakages of four groups were (0.67±0.67), (0.51±0.76), (3.07±1.09), (2.10±0.59)mm respectively,the coronal leakages of four groups were (0.42±0.46), (0.53±0.46), (2.62±0.98), (2.41±0.68)mm respectively. 〖JP2〗Significant differences were found between group A and group B, group C and group D in both apical and coronal leakage length. Conclusion The apical and coronal sealing abilities of GuttaFlow+single cone technique are greater than AHplus, so GattaFlow system can be applied in clinic.
