摘要: 目的:观察硅酸二钙-半水硫酸钙不同掺伴比率复合物的根尖封闭性能。方法:选取66颗单根管前磨牙,随机分成6个实验组,A组C1.4Si、B组C1.4Si/CSH10、C组C1.4Si/CSH30、D组C2.0Si、E组C2.0Si/CSH10、F组C2.0Si/CSH30(每组10颗)和两个对照组(每组3颗),采用protaper镍钛器械预备根管,将实验糊剂注入根管内,采用染料渗入法评价根尖封闭性。结果:A与C组,D与F组复合物根尖封闭性有统计学差异(P<0.05)。结论:硅酸二钙-半水硫酸钙复合物中半水硫酸钙的含量越高,根尖封闭性能下降。

Abstract: Objective: To observe the apical sealing ability of β-Ca2SiO3/CSH composite materials. Methods: Sixty-six premolars with the sigle root canal were used in this study. The teeth were randomly divided into six test groups,10 in each group. A was C1.4Si, B was C1.4Si/CSH10, C was C1.4Si/CSH30, D was C2.0Si, E was C2.0Si/CSH10, F was C2.0Si/CSH30. In addition,there were positive and negative control groups, 3 in each group. Protaper was used to prepare the root canal and the composite was filled into the root canal. The method of the dye penetration was performed to evaluate the apical sealing ability. Results: There were significant differences of the apical sealing ability between A and C or D and F(P<0.05). Conclusion: The more CSH of β-Ca2SiO3/CSH complex was, the larger value of the apical microleakage was.
