In vitro study of endodontic post cementation protocols that use resin cements.

Statement Of Problem: Sodium hypochlorite (NaOCl) may alter resin bond strength by deproteination of demineralized dentin collagen.

Purpose: To analyze the effect of NaOCl treatment on bond adhesion and tensile strength of different post cementation protocols in vitro.

Material And Methods: The periconductual dentin of 120 single-rooted, caries-free, unrestored human teeth was etched with 37% orthophosphoric acid.
