Resumen:
The photopolymerizable resins have greater color stability than resins chemical activation, but it is recognized that show some changes to polymerize andgetting old.The aim of this study was to observe the effect of aging simulated two optical properties of the resins, color and translucency, studying the reflectance mode in newly polymerized resins and after simulated getting old postcure.Two types of resins, Microhybrid and Nanoparticles, in the colors Translucent, A2 y B2 Enamel and A3 Dentin were used. The tests were performed on 80 specimensresins, polymerized by Halogen and LED lamps. The reflectance of the freshly polymerised resins and after thermocycling treatment in pigmenting substances tocause a simulated aging was studied. Measurements were made in a ?spectral Luminanciómetro? (Spectra Scan System Model PR 715, Photo Research), with ageometrically calibrated reflectance standard.
