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 examineddepth of cure, volumetric shrinkage, flexural strengthmodulus, fracture toughness, andpercent porosity. A mean and standard deviation were determined per group. A 1-wayANOVATukey test was performed per property alpha0.05. Percent porosity wasevaluated with a Kruskal-WallisMann-Whitney test alpha0.005. Significantdifferences were found between groups p0.001 per test type. Compared to the othercomposite restorative materials, SonicFill showed low shrinkage and percent porosity,high strengthflexural modulus and fracture toughness. However, depth of cure was lessthan manufacturers claim of 5mm.
