| Abstract | ||
| Aims: To investigate the effects of the incorporation of hydroxyapatite nanoparticles (HA NPs) with size (20 nm) at two concentrations (0.5% and 1%) on the thermal conductivity of heat-cured acrylic resin. Materials and methods: The total number of specimens was thirty which was divided into ten specimens (control, 0.5 % HA NPs, and 1 % HA NPs), the thermal conductivity was performed using Lee's disc apparatus. The statistical analysis was done by using the SPSS program including descriptive statistics, ANOVA, and Duncan's test at p ≤ 0.05. Results: The results demonstrated that there was a significant increase in the thermal conductivity for the PMMA-HA nanocomposite at HA nanoparticles (0.5%) and (1%) when compared to the control. Conclusions: the use of hydroxyapatite nanoparticles as dental fillers at 0.5% and 1% by weight increased the thermal conductivity of PMMA denture base material. | ||
