title: Effect of Scotchbond dependent on cavity cleaning, cavity diameter and cavosurface angle.
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.
