Group 1 received universal dental adhesive application in a self-etch mode followed by a build-up with RC. Group 2 received saliva as a contaminant, Group 3 received blood as a contaminant, Group 4 received a 1:1 blood-saliva mixture as a contaminant. Specimens from Groups 2, 3, and 4 were submerged into their respective contaminants for 15 seconds and dried prior to the adhesive application, followed by the protocol for Group 1. All specimens were stored in distilled water for 24 hours. Subsequently, the bonded specimens were subjected to \u03bcSBS testing using a universal testing machine. Failure mode of the debonded RMGIC surfaces was examined using scanning electron microscopy.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The \u03bcSBS from groups 1\u20134 were 10.76 \u00b1 3.03 MPa, 9.36 \u00b1 2.54 MPa, 6.55 \u00b1 1.67 MPa and 8.42 \u00b1 2.79 MPa, respectively. Contamination by blood and blood-saliva significantly decreased the \u03bcSBS (p&lt;0.001, p=0.029). Saliva contamination alone had no statistically significant effect on the \u03bcSBS (p=0.524).
