Abstract
Objectives: To evaluate the effect of different artificial aging on the fluorescence of resin composites. Material and Methods: Forty-five cylindrical specimens (6mm in diameter and 1mm thick) will be made of each composite resin: microparticulate (Durafill), microhybrid (Empress Direct) and nanoparticle (Filtek Z350). A baseline measurement of fluorescence by direct method using the fluo…
