Abstract
The objective of this study was to investigate the impact on thermal conductivity, thermal diffusivity, tensile strength and tear strength in the soft denture lining material by applying Calcium Carbonate Nanoparticles (CaCO3 NPs) to soft lining materials. CaCO3 NPs were applied to the heat cured soft lining material with 1.5% and 2% concentration by weight. Ninety specimens have been prepared according to formed tests. The thermal conductivity and thermal diffusivity of soft liner/CaCO3 NPs composites were measured, the strength of the tensile bond and the tear strength were also measured and the results show that thermal conductivity and thermal diffusivity in the experimental specimens were significantly increased compared to control specimens. The tensile bond strength between the soft liner material and denture base of the acrylic and the tearing strength showed a significant increase. Therefore, the addition of CaCO3 NPS can provide an increased thermal conductivity, thermal diffusivity as well as tensile bonding strength and tear strength for soft liner material.
