Bulk-fill composites have recently been introduced to the market and are receiving attention mainly because they can allow 4 mm increments without negative effects on polymerization, boasting very good characteristics of adaptation to cavities and a good degree of conversion (DC). Furthermore, their polymerization shrinkage appears to be lower than conventional composites, such as to … Continue reading Preheating of new Bulk-fill composite materials: polymerization shrinkage and conversion degree
