Abstract
This study aims to evaluate the resistance to staining and surface roughness of composites processed by CAD/CAM. One hundred and twenty specimens will be fabricated, 30 (n=10) in composite resin (Filtek Z350, 3M ESPE), 30 (n=10) in ceramic (IPS emax Press) and 60 (n=20) in hybrid ceramic - CAD/CAM (Lava Ultimate, 3M ESPE). Color (on white background) and translucency (on white and black b…
