树脂微拉伸粘结强度测试法的影响因素

目前常用微拉伸强度测试法对树脂的粘结强度进行评估。微拉伸强度测试法较传统的剪切强度测试有许多独特优点,然而该测试法会受到诸多因素的影响,使之不能准确反映树脂与牙体组织之间的粘结强度。这些影响因素主要包括离体牙储存方式、样本预备、不同的粘结系统以及固化方式等,已有学者对其进行了相关研究,该文就其研究成果作一综述。

Influencing factors of micro-tensile strength test

Micro-tensile strength test is commonly used to evaluate the resin bond strength.It has more unique advantages than the traditional shear test.However,whether it can accurately reflect the bond strength between tooth and resin will be affected by many factors such as storage methods,sample preparation,different bonding systems and curing methods.Some scholars have already studied these factors and this paper will review and summarize these factors.
