  The quality of composite polymerization has been of great concern for researchers. Curing of nanocomposites under long distance (8 mm) and extended light exposure through conventional (halogen and LED) and argon laser lamps is unclear in the literature. This study evaluated the influence of curing modes and filler particle size on hardness and degree of conversion of dental composites photo activated at an 8 mm distance. Light sources (LED 1100 mW/cm2-Bluephase; LED 700 mWcm2-Ultra-lume; halogen lamp 450 mW/cm2-XL3000; and argon-laser 500 mW/cm2-AccuCure), curing times (20 and 60 s), microhybrid (Filtek-Z250) and nanofilled (Filtek-Supreme) resins were investigated. Eighty samples (n=5) were made using Teflon molds. Hardness and degree of conversion were obtained for bottom/top surfaces of 2-mm increments. Data were submitted to ANOVA.. View More»
