Objective: To compare shear bond strength and the remaining adhesive index (RAI) of two types of primers: hydrophilic (Transbond™ MIP) and hydrophobic (Transbond™ XT Light Cure Adhesive y Rely-a-bond®) on bovine teeth enamel exposed to contamination (saliva and water) and without contamination. Materials and Methods: 99 permanent bovine incisors were used and divided into nine study groups, three groups for each primer: Group 1 , 2 and 3 with Transbond™ MIP; Group 4, 5 and 6 with Transbond™ XT Light Cure Adhesive; Group 7, 8 and 9 with Rely-a-Bond® and every primer was evaluated without contamination, and then contaminated with saliva and water. The measurements of shear strength bond were performed on the universal test machine INSTRON® at a rate of 0.5 mm per minute, RAI was evaluated in all samples. Results: The measurement of shear bond strenght in the non contaminated groups was similar to the Transbond™ XT Light Cure Adhesive and Transbond™ MIP primers, but significantly lower for the Rely-a-bond® primer (p<0.05). In the contaminated samples, the Transbond™ MIP primer had higher shear bond strength than the hydrophobic primers. Significant statistically differences were found in all groups (p<0.001). RIA was evaluated and it was found that the majority of groups had results of grade 0 and 1. Conclusions: Water and saliva contamination decreased shear bond strenght using hydrophobic primers. On the other hand, the hydrophilic primer was not affected by the water and saliva contamination.
