Thermopolymerized Acrylic Resin Immersed or Incorporated with Silver Nanoparticle: Microbiological, Cytotoxic and Mechanical Effect

Associated with the use of removable prostheses, the development of candidiasis, called prosthetic stomatitis, is frequently observed. In view of the application of silver nanoparticles (AgNP) in dentistry that may offer antimicrobial effect, the aim of this study was to evaluate the effect of adding AgNP with different concentrations during thermopolymerization or immersion of acrylic in this substance in the properties antifungal, mechanical and cytotoxic. The groups were divided: addition of 1% silver nanoparticle solution (G1), addition of 2.5% silver nanoparticle solution (G2), addition of 5% silver nanoparticle solution (G3), immersed for 10 min in aqueous silver nanoparticle solution (G4), immersed for 24 hours in aqueous silver nanoparticle solution (G5). In the cytotoxicity assay, at all evaluation times, all groups showed cytotoxic effect (p
