| 摘 要： | 目的:比较纤维桩和预成金属桩使用不同粘接系统时根管各部的剪切粘接强度。方法:自制相同尺寸的碳纤维桩、预成金属桩,分别与全酸蚀系统ONE-STEP/C&B CEMENT或自粘接系统Rely X Unicem在人上颌中切牙根管内(n=6),用Synergie综合测试仪对各根管段行剪切粘接实验,行裂区方差分析。结果:剪切粘接强度分别为:纤维桩全酸蚀组:(11.14±1.26)MPa,纤维桩自粘接组:(5.04±0.94)MPa,金属桩全酸蚀组:(13.62±1.16)MPa,金属桩自粘接组:(7.80±1.36)MPa。预成金属桩剪切粘接强度优于碳纤维桩(P<0.000 1),全酸蚀系统优于自粘接系统(P<0.000 1)。根管各段由冠方向根方剪切粘接强度逐渐减弱。结论:预成桩修复的剪切粘接强度受桩材质、粘接系统及根管不同部位等因素的影响。

| Abstract: | Objective: To investigate the shear bond strength between different prefabricated posts and root canals using different adhesive systems.Methods: C-posts and KF-posts were placed into canals of manxillary central incisors using one step-plus/C&B cement(OSP/CB) and Rely X Unicem(RXU) adhesive systems respectively(n=6).The push-out test was performed on different sections of the roots by Synergie tester.The data were analyzed with split-plot ANOVA.Results: The average push-out strengths of C-post with OSP/CB,... |
