OBJECTIVE
To explore the effect of adding different percentages of nanostructured silver vanadate decorated with silver nanoparticles (β-AgVO) to dental porcelains, evaluating the antimicrobial activity and the influence on the mechanical properties.
METHODS
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.
RESULTS
There was a statistically significant difference between groups for mechanical and microbiological analyses.
SIGNIFICANCE
The modification of dental porcelains, with the incorporation of β-AgVO, influenced the mechanical properties of the material and demonstrated antimicrobial activity at certain concentrations.
目的
探索在牙科瓷中添加不同比例纳米结构银钒酸负载纳米银（β-AgVO）对其抗菌活性和机械性能的影响。
方法
使用两种商业品牌（IPS InLine 和 Noritake Cerabien ZR）制作了 36 个样本，每个浓度均设置了对照组和 0.5%、1%、2.5%、5%共 5 个实验组。对机械性能进行了维氏硬度试验和粗糙度试验，对微生物进行了 XTT 和 CFU 分析。
结果
机械性能和微生物分析结果显示组间存在统计学差异。
结论
通过向牙科瓷中添加β-AgVO 对其进行修饰，影响了材料的机械性能，并在一定浓度下表现出抗菌活性。
