Abstract
Objective: To evaluate the effect of different artificial aging on roughness, hardness and weight loss of "bulk-fill" composites, as well as the characterization on the surface after the aging procedures. Material and Methods: Sixty three cylindrical specimens of 6 mm in diameter and 1mm thickness will be made for each composite: Filtek " Z350 XT, GrandioSO, Admira Fusion x-tra ®, Filtek …
