A light-emitting diode (LED) unit was used for photoactivation and after 24h at 37 °C in absolute humidity, teeth were sectioned into slices of 1 mm divided by different root thirds (cervical, middle and apical) and submitted to the push-out bond strength test. Two-criteria ANOVA was used to determine the statistical significance between groups (p<0.05).</p> <p><strong>Results:</strong> No statistical difference in bond strength between group cemented as manufacturer’s instructions and group submitted to deproteinization was detected (p>0.05). As well as there was no statistical difference between the different root thirds evaluated (p>0.05).</p> <p><strong>Conclusions:</strong> The deproteinization protocol proposed was not able to improve the bond strength of self-adhesive cement to root dentin.</p>}, number={2}, journal={Giornale Italiano di Endodonzia}, author={Gaviolli, Emanuela and da Silva, Matheus Rubens and Graunke, Alexandra and Chisini, Luiz Alexandre and Van de Sande, Françoise Hélène and Varella de Carvalho, Rodrigo}, year={2020}, month={Oct.} }
