Examining exposure reciprocity in a resin based composite using high irradiance levels and real-time degree of conversion values

Nov 23, 2017 by in Dental Materials Comments Off on Examining exposure reciprocity in a resin based composite using high irradiance levels and real-time degree of conversion values

Abstract Objective Exposure reciprocity suggests that, as long as the same radiant exposure is delivered, different combinations of irradiance and exposure time will achieve the same degree of resin polymerization….
