Materials and methods: 20 human molars donated by UNIFAL teeth bank were prepared and, after being divided into two groups, ceramic or composite cylinders were luted to them with two resin-based cements (conventional and self-adhesive). Prepared teeth were sectioned vertically in both buccal-lingual and mesio-distal directions, to obtain 8 mm high, square-shaped “sticks” that were subject to microtensile bond strength test, the necessary force to tracture them was evaluated. Results were subject to two-way ANOVA and Tuckey test. Results: minimum and maximum forces to disrupt conventional cement were greater than the ones required for self-adhesive cement, as well as mean bond strength, regardless the restorative material. Tukey test showed that diferences were statistically significant, regardless the restorative material. Conclusion: the difference between microtensile bond strength values of resin cements tested was statistically significant; the restorative materials did not influence microtensile bond strength values, with no statistically significant differences.application/pdfAcesso Abertohttp://creativecommons.org/licenses/by-nc-nd/4.0/Resistência à TraçãoCimentos de ResinaODONTOLOGIA::MATERIAIS ODONTOLOGICOSDissertaçãoMoretti Neto, Rafael Tobias
