Abstract
This study assessed the antifungal effect of modified denture acrylic resin containing Au, Pt and Ag
nanoparticles (NPs) respectively and evaluated their physical aspects to produce a antimicrobial
nanocomposite material. Each colloidal NPs suspension was preliminary combined to the denture powder
in different doses (0, 10, 50, 100 and 200 ppm) then mixed with monomer. The antifungal (C. albicans)
effect was assessed using a fluorescence activated cell sorting, thermal analysis and color stability test
were conducted to characterize those nanocomposites. As compared to control (0 ppm), the significant
reductions of viable cell adherence on the nanocomposite were shown at the dose of 200 ppm in all
NPs and 100 ppm in AgNPs. Addition of NPs to PMMA resulted in successful co-polymerization phase
with stable thermal property, however, lack of color stability should be improved.
