Abstract
Degree of surface roughness of five different composite materials
for cavity fillings (Adaptic, Aura fill, Command, Heliosit and Silux) was
assessed after mechanical finishing. Various grinders (diamond and carbide burs, and soflex disks) were used in polishing the composite filling surfaces. Polishing was carried out 10 minutes and 14 days after the material polymerization. The ground surface was then observed by a scanning electron microscope and the surface roughness expressed in microm. Better surface polish and lower degree of roughness were observed when polishing was performed 14 days after polymerization. Best results were obtained in specimens polished by soflex disks and diamond burs.
