Data on bond strength of resin cement systems to CAD/CAM resin composite after aging

CAD/CAM resin composite crowns are inexpensive toothcolored prostheses that have been widely used. However, bonding between CAD/CAM resin composites and resin cements could be difficult since the resin composite is highly cross-linked. There is limited existing data on the resin cements' bond strength with different monomers to CAD/CAM resin composites. In this study, CAD/CAM resin composite was bonded to an SUS rod with three different resin cements following treatment of the bonding surface using the manufacturer's recommended primer. After storing the specimens in water at 37 degrees C for 24 h, half of them were tested immediately and half were thermocycled for 10,00 0 cycles in water for a dwell time of 20 s at 5 and 55 degrees C. The means of the tensile bond strength and standard deviations were determined for each resin cement and testing condition. The data were compared using two-way ANOVA and Bonferroni's multiple comparison tests at 95% confidence level. (C) 2021 The Authors. Published by Elsevier Inc.
