Description
Summary:Purpose To investigate the potential of adding silver‐nanoparticle‐containing amorphous calcium phosphate microparticles as bioactive fillers into commercially available nonbioactive dental resin cement. Materials and Methods Experimental cement was formulated by adding 7.5% silver‐nanoparticle‐containing amorphous calcium phosphate microparticles to Multilink Automix resin cement (Ivoclar Vivadent). The experimental cement was evaluated for shear bond strength (N = 11 per group) and demineralization/remineralization (N = 16 per group), with BioCem® Universal BioActive cement (NuSmile) as the positive control and Multilink Automix cement as the negative control. One‐way analysis of variance and post hoc tests were used to assess the significance of differences among or between the groups Results The addition of silver‐nanoparticle‐containing amorphous calcium phosphate microparticles at the level of 7.5% by weight into Multilink Automix did not have a statistically significant effect on the shear bond strength (p > 0.05), but statistically significantly increased the depth of remineralization on both dentin and enamel (p = 0.01 and p < 0.001, respectively) when compared to Multilink Automix alone. The experimental cement prepared in the present study was comparable to BioCem® on the depths of remineralization on both dentin and enamel (p = 0.59 and p = 0.99, respectively). Conclusion When incorporated into nonbioactive commercial dental resin cements as bioactive fillers at the level of 7.5% by weight, silver‐nanoparticle‐containing amorphous calcium phosphate microparticles could provide remineralization potential without affecting the shear bond strength.
