Abstract

The effect on bond strength of smear layer removal (40% polyacrylic acid or 10% phosphoric acid) versus smear layer conditioning for dentin bonding agents requiring conditioning was compared. Results indicated no difference in shear bond strength for groups in which the smear layer was conditioned or removed with phosphoric acid. Smear layer removal with polyacrylic acid resulted in lower bond strengths between DBAs and dentin than either phosphoric acid removal or conditioning (P less than 0.01). Scanning electron photomicrographs of dentin treated with each dentin bonding agent revealed various surface morphologies.

摘要

比较了对于需要进行预处理的牙本质粘结剂，去除玷污层（40%聚丙烯酸或10%磷酸）与预处理玷污层对粘结强度的影响。结果表明，用磷酸预处理或去除玷污层的组之间的剪切粘结强度没有差异。用聚丙烯酸去除玷污层导致牙本质粘结剂与牙本质之间的粘结强度低于用磷酸去除或预处理玷污层的情况（P小于0.01）。用每种牙本质粘结剂处理后的牙本质扫描电子显微照片显示出各种表面形态。
