Abstract
Purpose: The objective of the study was to assess the antimicrobial activity of acrylic denture base containing nanosilver and nanogold to; S. aureus, E. coli and C. albicans. Methods: Three concentrations of silver and gold nanoparticles (0.01 %, 0.1%, 1% of polymer weight) were added to MMA monomer, cured samples of modified PMMA were evaluated for their antimicrobial activity to three micro-organisms using Broth Microdilution Assay. Results: Both nanosilver and nanogold showed antimicrobial activity to the tested micro-organisms. Conclusion: Addition of nanogold and nanosilver to acrylic bases could improve their antimicrobial activity.
