颜色对树脂粘结剂抗张强度及粘结强度影响的研究

Effects of colour on diametral tensile strength and bonding strength of resin cement

目的:研究颜色的不同对树脂粘结剂径向抗张强度及其与瓷粘结强度的影响。方法:分别制作不同颜色树脂粘结剂的径向抗张强度试件及粘结试件,测其径向抗张强度和剪切强度,统计分析所得数据。结果:不同颜色树脂粘结剂的径向抗张强度间及粘结后剪切强度间无显著性差异。结论:充分固化后Panavia F树脂粘结剂颜色的不同对其径向抗张强度和粘结强度无显著性影响。

Objective To study the effects of colour on diametral tensile strength and bonding strength of resin . Methods The specimens for diametral tensile strength test and bonding strength test were made and divided according to deferent color .Then the specimens were tested on a universal testing machine. Data were analyzed with ANOVA （P〈.05）. Results There was no significance among all color groups on either diametral tensile strength or bonding strength. Conclusion Color had no obvious effects on diametral tensile strength and bonding strength of Panavia F resin cement cured totally.
