Abstract

This study examined the hypotheses that the use of a self-etching-adhesive improves the adhesion of EndoRez to dentin, and that both techniques are unaffected by the prolonged use of NaOCl when EDTA is used as the final rinse. A tensile bond testing design was employed with composite cylinders bonded to dentin using: (a) 17% EDTA-2 min/EndoRez; (b) 6.15% NaOCl-1 h/EDTA-2min/EndoRez; (c) EDTA-2 min/Clearfil Liner Bond 2V/EndoRez; and (d) NaOCl-1 h/EDTA-2min/Clearfil Liner Bond 2V/EndoRez. Fractographic analyses of debonded specimens were performed using SEM. Two-way ANOVA and Tukey test revealed higher tensile bond strengths with the self-etching-adhesive-modified EndoRez technique (p < 0.001). Sealer tags pulled away from dentinal tubules when EndoRez was used alone, whereas mixed failures occurred within sealer tags, hybrid layers, adhesive, and sealer in the self-etching-adhesive-modified EndoRez technique. Both techniques were unaffected by the prolonged use of NaOCl (p > 0.05) when EDTA was employed as the final rinse.
