Influence of β-AgVO3 nanomaterial incorporation on mechanical and microbiological properties of dental porcelain

To explore the effect of adding different percentages of nanostructured silver vanadate decorated with silver nanoparticles (β-AgVO3) to dental porcelains, evaluating the antimicrobial activity and the influence on the mechanical properties.Thirty-six specimens were made, for each concentration, control group, 0.5%, 1%, 2.5% and 5%, using two commercial brands: IPS InLine and Noritake Cerabien ZR. For the analysis of mechanical properties, the Vickers microhardness test and the roughness test were performed. For the antimicrobial analysis, the XTT and CFU assays were performed.There was a statistically significant difference between groups for mechanical and microbiological analyses.The modification of dental porcelains, with the incorporation of β-AgVO3, influenced the mechanical properties of the material and demonstrated antimicrobial activity at certain concentrations.
