Abstract
The aim of this study was to assess the relation between the number of free radicals generated and the polymerization depth in two different commercial brands of resin composites with different colors and translucence. Electron paramagnetic resonance quantified the radical populations through relative intensity (I r) of free radicals generated, and radical decay was monitored. Sample translucence and the classical polymerization depth were measured. The analysis indicated that resin with more color pigments (MA4, I r = 0.73 a.u) or more opacity components (ODA2, I r = 0.84 a.u) generated smaller populations of free radicals and have the lower polymerization depth than clearer (M, I r = 1.20 a.u and MA2, I r = 1.02) or more translucent (OEA2, I r = 1.00 a.u) composites for the same light-curing time. It seems that irradiation doses have to be adequate to more colored and less translucent resins.
