Translucency of Nanoparticles Reinforced Denture Base Materials

Aims:To evaluate the effect of adding salinized zirconium oxide (ZrO2) and silicon oxide (SiO2) nanoparticles in two concentrations on the translucency of heat-cured denture base material.Materials and methods: Fifty discs (152.5mm)were prepared in accordioning to the manufacturer's instructions and divided into five groups, control without nanoparticles reinforcement, 1%ZrO2, 3%ZrO2, 1%SiO2 and 3%SiO2 NPs reinforcement.Translucency was measured using a colorimeter.Results: The result showed a highly significant (P 0.01) decrease in the translucency.The ZrO2 Np reinforced more reduced in translucency than the SiO2 Np reinforced group.The 3% by weight is more reduced than 1% by weight.Conclusions: Both nanoparticles reduced the translucency.
