摘要: Abstract Objective The purpose of this study was evaluate, for the first time, impact incorporation nanostructured silver vanadate (β-AgVO3) in antibiofilm and mechanical properties dental acrylic resins (poly(methyl methacrylate), PMMA). Design β-AgVO3 synthesized characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy, microanalysis (SEM/EDS). Resins specimens were prepared with 0–10% wt.% SEM, XRD optical microscopy. antibiofim activity samples against Candida albicans Streptococcus mutans investigated XTT reduction test, colony-forming units (CFUs), confocal laser microscopy (CLSM). flexural strength, hardness, surface roughness containing compared pure PMMA matrix. Results 10% significantly reduced metabolic C. S. (p 0.05). However, strength decreased addition amounts greater than 1% Conclusions additions resin may have an on inhibition biofilm main microorganisms associated prostheses. viability clinical use should be evaluated function changed promoted some properties.
