Özet
Objective: The aim of this study was to investigate the effect of cavity disinfectant application on the shear bond strength of current Computer Aided Design/Computer Aided Manufacturing (CAD/CAM) blocks to dentin. Methods: Samples of three CAD/CAM blocks, Celtra Duo, Vita Enamic, and Tetric CAD (2×3×3 mm) were obtained from each material under water cooling. Chlorhexidine digluconate (CHX) was applied to half of the samples, while the other half remained untreated. Variolink DC and Variolink LC resin cements were used to bond the blocks to the teeth. All samples underwent testing to measure shear bond strength. Fracture failure patterns were examined using a stereomicroscope. Statistical analysis was performed using a two-way analysis of variance (ANOVA). Results: Celtra Duo exhibited the highest bond strength, while composite block showed the lowest bond strength value (P<.05). The use of CHX resulted in a decrease in the SBS of the Tetric CAD in samples cemented with Variolink DC (P<.05), but there was no statistically significant difference observed in the bond strength of the Vita Enamic and Celtra Duo (P<.05). CHX application decreased the SBS in all blocks in the Variolink LC cemented samples (P<.05). Conclusion: The results of the study showed that cavity disinfectants had a mostly negative effect on the bonding of CAD/CAM blocks to dentin.
