Abstract

The effect of Scotchbond on the wall-to-wall polymerization contraction of a visible light activated microfilled resin was investigated in cavities prepared in extracted human teeth. The cavities were cleaned either with water spray or a saturated acidic solution of EDTA, the latter giving significantly better results. The cavities were prepared with cavosurface angles between 90 degrees and 160 degrees. A highly significant improvement of marginal adaptation was found with increasing cavosurface angle.

摘要

在拔除的人牙制备的窝洞中，研究了Scotchbond对可见光固化微填料树脂壁间聚合收缩的影响。窝洞分别用水喷雾或EDTA饱和酸性溶液清洁，后者效果明显更好。制备的窝洞洞壁角在90度至160度之间。发现随着洞壁角增大，边缘适应性有极显著改善。
