Purpose: To examine the bond quality of a luting cement after the incorporation of an antibacterial molecule into the primer. Methods: Eight non-carious human third molars were randomly divided in two equal groups. Cylindrical composite blocks were luted with Panavia F (Group I) and Panavia Prototype (Group II). Seating pressure was applied during the entire three-minute polymerization period of the resin cement to minimize fluid interferences from the underlying dentin. After being stored in distilled water for 24 hours, 0.9 x 0.9 mm sticks were produced from these luted specimens for microtensile bond testing and SEM examination. Results: No statistical difference in the bond strength between the control Group and the experimental Group was detected (p>0.05). From SEM analysis, between the two groups, no significant differences were found. Conclusions and clinical significance: The addition of an antibacterial monomer (MDPB) to the existing Panavia F luting cementation system does not negatively affect final bond quality and might extend the application of the cement.

Abstract

Purpose: To examine the bond quality of a luting cement after the incorporation of an antibacterial molecule into the primer. Methods: Eight non-carious human third molars were randomly divided in two equal groups. Cylindrical composite blocks were luted with Panavia F (Group I) and Panavia Prototype (Group II). Seating pressure was applied during the entire three-minute polymerization period of the resin cement to minimize fluid interferences from the underlying dentin. After being stored in distilled water for 24 hours, 0.9 x 0.9 mm sticks were produced from these luted specimens for microtensile bond testing and SEM examination. Results: No statistical difference in the bond strength between the control Group and the experimental Group was detected (p>0.05). From SEM analysis, between the two groups, no significant differences were found. Conclusions and clinical significance: The addition of an antibacterial monomer (MDPB) to the existing Panavia F luting cementation system does not negatively affect final bond quality and might extend the application of the cement.
