After restoration, the dentin/resin interface was tested by microtensile bond strength and failure mode was analyzed by Scanning Electron Microscopy. Data were analyzed by ANOVA followed by Tukey.<span class="Apple-converted-space">&nbsp;</span></p><p><strong>Results:</strong> G1 had higher bond strength than the rest of the groups. There were no statistically significant differences among G2, G3, and G4 (p&gt;0.05).<span class="Apple-converted-space">&nbsp;</span></p><p><strong>Conclusions:</strong> The adverse effect of NaOCl on bond strength persisted even after 14 days after exposure.</p> ER -
