Resumo: The replacement of metallic infrastructure by dental ceramics brings good aesthetics and greater biocompatibility of fixed prostheses. The material of choice is zirconia (ZrO2) because of its excellent mechanicals properties. Conventional cementing techniques are not effective for this type of infrastructure, and 10-methacryloyloxy-decyl-dihydrogenphosphate (10-MDP) should be used as a bonding agent. The present study aims to characterize 10-MDP with zirconia using micro-Raman spectroscopy. For this, (1) micro-Raman spectroscopy was used to find the vibrational peak of ZrO2 binding with 10-MDP and calcium, not yet demonstrated in the literature. (2) The micro-shear bond strength of the dual resin zirconia cement with the presence of 10-MDP in the composition of the primer and the self-adhesive resin cement. (3) If the presence of 10-MDP without ceramic primer changes the degree of conversion of the conventional dual resin cement to a zirconia. In this study the 1545cm-1 and 1562cm-1 peaks were found to refer to zirconia binding with 10-MDP and the 3391cm-1 and 3442cm-1 peaks relative to the 10-MDP calcium binding. The presence of 10-MDP in both the ceramic primer and the self-adhesive resin cement improved a micro-shear bond strength of the resin cement. The high concentration of 10-MDP was not buffered by ZrO2 and reduced the degree of conversion of the resin cement to the experimental primers, but not with the low concentration of 10-MDP. We can conclude that the non-destructive method of micro-Raman spectroscopy was able to characterize a chemical union of 10-MDP with a zirconia, and that such monomer should be used in low concentrations in primers for zirconia to avoid reducing the polymerization of the cement residue.
