In addition, the elemental composition (EC) of dentin after removal of the collagen fibrils was analyzed. Materials and Methods: Forty third molars received two cavities and were divided into four groups according to dentin treatment: CTRL\u2014no pre\u2010treatment; Na10\u201410% NaOCl for 30 s; Ca10\u201410% CaOCl for 30 s, and Ca15\u201415% CaOCl for 30 s. The cavities were filled using an acetone\u2010based adhesive system and a resin composite; they were then subjected to thermal cycling for 5,000 cycles, immersed in methylene blue for 4 h and sectioned into 1\u2010mm thick slabs. Two examiners evaluated two slices per tooth using a stereomicroscope and assigned the degree of infiltration (scores 0\u20133). The data were analyzed using the Kruskal\u2013Wallis (<jats:italic>\u03b1<\/jats:italic>\u2009=\u20090.05). Four teeth received surface treatment according to the groups and were submitted to SEM and EDS to carry at the EC. Results: There was no significant difference between the experimental groups (<jats:italic>P<\/jats:italic>\u2009=\u20090.533). CaOCl alters the morphology and surface composition of the dentin, resulting in an increase in the amount of calcium in the interface. Conclusions: When used prior to an acetone\u2010based adhesive system, CaOCl did not produce any differences in microleakage when compared to the CTRL group or to the Na10 group. <jats:italic>Microsc.
