摘　　要：目的探究低温等离子处理对纤维桩黏结强度的影响。方法将32个纤维桩试样随机分为对照组和等离子体照射组。对照组不作特殊处理,等离子体照射组进行低温等离子体处理。使用力学机器对试样进行拉伸测试,比较2组的黏结强度。结果等离子体照射组平均剪切强度明显高于对照组,差异有统计学意义(P<0.05)。结论低温等离子体处理可以提高纤维桩的黏结强度。Objective To investigate the effect of low temperature plasma treatment on the bond strength of fiber posts.Methods Thirty-two fiber posts samples were randomly divided into control group and plasma irradiation group.The control group was not subjected to special treatment,and the plasma irradiation group was subjected to low-temperature plasma treatment.Other processes were the same between the two groups in this study.Then,the bond strength of each specimen was tested with a biomechanical machine.Results The average shearing strength of the plasma irradiation group was significantly higher than that of the control group,and the difference was statistically significant（P〈0.05）.Conclusion Low-temperature plasma treatment can improve the bond strength of fiber posts.
