Effect of a sodium hypochlorite gel on dentin bonding

摘要

It has been suggested that the hybrid layer (HL) does not play any important role I the mechanism of adhesion to dentin. To substantiate this hypothetical insignificance of the HL, sodium hypochlorite (NaOCl) has been used to remove collagen from etched dentin prior to bonding. Objectives: The present study was conducted to determine the effect of a commercial 10/100 NaOCl gel on the dentin shear bond strengths And HL ultra-morphology of two simplified dentin adhesives. The null hypothesis tested was that treatment of etched dentin collagen with NaOCl would not compromise dentin bonding.
