silicon carbide papers with a brief rinsing in tap water between each grit. For each material, 36 specimens were randomly divided into six groups of six, and immersed in two solutions: distilled water (pH 6.8) and 0.01 mol⁄L lactic acid (pH 4) at 37 C for either 24
2013/3/31· Dentin occlusal surfaces were exposed and further polished on 400, 600 and 800-grit silicon-carbide paper. The surfaces were divided into two halves in the labial-lingual orientation. After etching, the adhesives were used either in double coats, or four coats on the halves of the same tooth followed by air evaporation for each layer and finally light curing.
