Physical Properties of Dual-Cured Composite Resin Restorative Materials

Abstract

The purpose of this study was to compare the properties of new dual-cure, bulk-fill restorative composites (Injectafil DC, Apex; HyperFIL, Parkell) to a hybrid composite material (Filtek Z250, 3M/ESPE). Depth of cure, fracture toughness, porosity, microleakage, and volumetric shrinkage were examined. Except for fracture toughness, significant differences were found between groups per property. Compared to the incrementally placed composite (Filtek Z250), the new dual-cure, bulk-fill restorative composites (HyperFIL, Injectafil) in self-cure mode had unlimited depth of cure, similar fracture toughness and porosity formation, but greater polymerization shrinkage and microleakage.
