Abstract
The aim of this study was to evaluate of adding fluorapatite nanoparticles on compressive strength of dental amalgams. An amalgam alloy powder (World-Cap?) was added and mixed with 1 wt%, 2 wt% and 4 wt% of fluorapatite nanoparticles, respectively. The original alloy powder was used as a control. Alloy powders were examined using X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy dispersive X-ray analysis (EDXA). The results of compressive strength tests showed that for the amalgam with 1 wt% and 2 wt% fluorapatite nanoparticles, the compressive strength is comparable with control sample and fluorapatite particles did not affect the compressive strength of amalgam alloy. For the amalgam with 4 wt% nanoparticles, the compressive strength was lower than the control sample?s. The results indicated that the fluorapatite nanoparticles can be added to amalgam alloy in less than 2 wt% and induce more biocompatibility and bioactivity to amalgam restorations
