Abstract

The purpose of this study was to compare the tensile bond strengths (TBSs) and failure mode of 4-META/MMA-TBB resin to 60 degrees C-heated and unheated bovine dentin, especially to investigate the influence of ferric chloride contained in citric acid pre-conditioning. In addition, the effect of HEMA priming for heated dentin was also evaluated. The TBSs to heated dentin were significantly lower than those to unheated dentin. Adhesive failures were observed in most specimens of the heated and HEMA-non primed group. HEMA application to heated dentin significantly increased the TBSs in each acid conditioning, which were also significantly higher than those of the unheated and ferric chloride-contained citric acid-conditioned group. It was clarified that heating dentin decreased the bond strength without HEMA priming even if the dentin surfaces were acid conditioned with 10-3, while HEMA priming after acid conditioning recovered the bond strength.

摘要

本研究的目的是比较4-META/MMA-TBB树脂与60℃加热和未加热的牛牙本质的拉伸粘结强度（TBSs）及失效模式，尤其要研究柠檬酸预处理中所含氯化铁的影响。此外，还评估了HEMA对加热牙本质的预处理效果。加热牙本质的TBSs显著低于未加热牙本质的TBSs。在加热且未用HEMA预处理的组的大多数标本中观察到粘结失败。对加热牙本质应用HEMA在每种酸预处理中均显著提高了TBSs，且这些TBSs也显著高于未加热且含氯化铁的柠檬酸预处理组。结果表明，即使牙本质表面用10⁻³酸预处理，加热牙本质在未用HEMA预处理时也会降低粘结强度，而酸预处理后进行HEMA预处理可恢复粘结强度。
