Physical Properties of a New Sonically Placed Composite Resin Restorative Material
Abstract
A new nanohybrid composite activated by sonic energy (SonicFill, Kerr) has beenrecently introduced as a single-step, bulk-fill restorative material. The purpose of thisstudy was to compare the physical properties of SonicFill to various other representativecomposite restorative materials. The following physical properties were examined:depth of cure, volumetric shrinkage, flexural strength/modulus, fracture toughness, andpercent porosity. A mean and standard deviation were determined per group. A 1-wayANOVA/Tukey test was performed per property (alpha=0.05). Percent porosity wasevaluated with a Kruskal-Wallis/Mann-Whitney test (alpha=0.005). Significantdifferences were found between groups (p<0.001) per test type. Compared to the othercomposite restorative materials, SonicFill showed low shrinkage and percent porosity,high strength/flexural modulus and fracture toughness. However, depth of cure was lessthan manufacturers claim of 5mm.
