    Author(s): Mostafa Ehsan Al-Douri* and Mohammed Mouyad Sadoon

    Aim: Examine the influence of Zinc Oxide (ZnO) nanoparticles on the flexural strength hardness and surface roughness of 3D printed denture base resin. Materials and methods: The study was conducted by adding ZnO nanoparticles in concentrations of 2%, 3% and 4% to 3D printed denture base resin and assessing the influence of the addition on some mechanical and physical characteristics of the resin, including flexural strength, hardness and surface roughness. The findings were evaluated using descriptive statistics (standard deviations and means), Analysis of Variance (ANOVA) and duncan's multiple range tests using the SPSS software. Results: The results showed statistically significant increases in flexural strength values for nanoparticles employed at all concentrations, with the highest flexural strength seen .. Read More»
