Synthesis and Characterization of Zinc Oxide Nanoparticles-based Dental Cement

Abstract

Dental cement-based mixture of zinc oxide and eugenol is one of the commonly used dental cement. One of the major shortcomings that limit its application is dental cement zinc oxide and eugenol has detrimental mechanical properties. This study aims to carry out the synthesis and characterization of nano-based dental cement of zinc oxide mixed with eugenol with the hypothesis that zinc oxide nanoparticles will provide better mechanical properties. Physical and mechanical properties of cement-based dental cement oxide nanoparticles will be compared with dental cement zinc oxide microparticles.Mixing eugenol and ZnO nanoparticles were made by the composition of the powder 0.4 g, 0.45 g, 0.5 g, 0.55 g, 0.6 g and 0.2 mL of fluid. ZnO nanoparticles as a powder slowly mixed with liquid, so as to produce pasta. Methods of analysis include compressive strength, hardness and microstructure observation. From a series of studies and analysis, the surface morphology of the samples obtained by the nanoparticles-based dental cement is smoother and has a little fracture compared with microparticles-based dental cement. Likewise, the mechanical analysis of dental cement, ZnO nanoparticles can increase the compressive strength and hardness of thematerial. The conclusions are that the addition of nanoparticles can enhance physical and mechanical characteristics. Keywords: Dental cement, Zinc oxide eugenol, Physical and mechanical properties.
