摘要: Abstract The aim of this work was to evaluate the effect addition sodium montmorillonite (Na+Mt) on flexural strength, modulus, degree conversion, steady state shear viscosity and complex Bis-GMA (2,2-bis-[4-(methacryloxypropoxy)-phenyl] propane)/TEGDMA (ethane-1,2-diylbis(oxy)) bis (ethane-2,1-diyl) bis(2-methylacrylate) resin. Two types clay polymer nanocomposites (CPN) were prepared, first one by using as received second adding previously dispersed in water (Na+Mt/H2O). Sodium added at different contents: 0.1, 0.2, 0.3, 0.4 parts per hundred resin (phr) Bis-GMA/TEGDMA for each type CPN. A resin, without montmorillonite, used control. Two-way ANOVA Tukey's test applied statistical analysis. Comparisons performed a significance level α = 0.05. Statistical analysis revealed that or water, had no strength (p = .886), modulus (p = .809) conversion (p = .742). Nevertheless, content significantly influenced (p = .004) (p
