title: Properties of dual-cure, bulk-fill composite resin restorative materials.
abstract: The purpose of this study was to compare the properties of 2 new dual-cure, bulk-fill restorative composite resins to those of a hybrid composite resin material. Depth of cure, fracture toughness, porosity, microleakage, and volumetric shrinkage properties were examined. With the exception of fracture toughness, significant differences were found among materials. Compared to the incrementally placed hybrid composite, the dual-cure, bulk-fill restorative composites in self-cured mode had unlimited depth of cure, similar fracture toughness and porosity formation, and greater polymerization shrinkage and microleakage.
