ABSTRACT
Objectives: to see the effect of CPP-ACP containing fluoride on enamel on the shear bond strength of composite resins. Methods: 10 samples of post-extraction premolars were divided into two groups which was soaked in CPP-ACPF and artificial saliva. Both groups were given repeated treatments for seven days and stored in an incubator at 37°C. On the eighth day, all samples were affixed with composite resin and tested for shear bond strength using a Universal Testing Machine with a 0.5mm/min speed. The average shear bond strength value in the control group was 9.57 MPa, and in the treatment group, 6.61 MPa. The One-Way ANOVA test showed no significant effect of adding CPP-ACP containing fluoride to enamel on the shear bond strength of the composite resin (p>0.05). Conclusion: Giving CPP-ACP containing fluoride to enamel does not affect the shear bond strength of the composite resin.
