Abstract

Objective: To evaluate the effect of the Carisolv™ system on the dentin substrate of human and bovine (permanent and primary). Methodology: 8 human teeth and 8 bovine teeth were selected. They were divided according to treatment [35% phosphoric acid gel(PA) for 15s and Carisolv™ system(C)] and substrate type into [human and bovine primary teeth. human and bovine permanent teeth]. The teeth were ground that in SiC paper until dentin was reached. The C treatment was accomplished according to the manufacturer's instructions, followed by PA for 15s. The specimens were prepared for SEM analyses. Dentin tubules, intra and intertubular dentin were analyzed. Based on the results found It could be concluded C system produced expressive alteration on the bovine teeth (permanent and primary ones) and permanent human teeth. with tubular disclosing and decrease of the peri and intertubular dentin. Otherwise, the primary teeth just showed the tubules disclosing and slightly alteration of the peri and ínter tubular dentin.
