The Effects of Magnesium Oxide Nanoparticles Addition on Flexural Strength of Cold-cured Acrylic Resin material

Aims: This study investigates the effects of addition magnesium oxide Nanoparticles(MgO NPs) with size (50 nm) on flexural strength cold˗cured acrylic resin. Materials and methods: Forty specimens were made, which divided into four groups (10 for each group) control group (pure without addition), containing 1.25% MgO NPs, 2.5%MgO a 5%MgO test was performed using universal testing machine, FTIR (BRUKER LASER CLASS 1). The statistical analysis done by SPSS program including descriptive statistics, ANOVA, Duncan΄s at p ≤ 0.05. Results: Maximum mean belong to NPs,the minimum belongs 5% NPs. Conclusion: NPs affected cold-cured resin, it improved low concentration but decreased higher concentratios.
