title: The effect of six polishing systems on the surface roughness of two packable resin-based composites.
abstract: OBJECTIVE
  To evaluate the surface roughness of two packable composites after finishing and polishing with six different systems.
  
  
  METHODS
  Solitaire and Alert composite samples were prepared and polished with Poli I and Poli II aluminum oxide pastes, Ultralap diamond paste, Enhance finishing points, Politip rubber polishers, fine and extra fine diamond burs, and 30-blade tungsten carbide burs according to the manufacturers' instructions. The polished surfaces were then evaluated with a profilometer and a scanning electron microscope.
  
  
  RESULTS
  Solitaire composite resin presented the smoothest surfaces when polished with Poli I and II aluminum oxide pastes, Ultralap diamond paste, Politip finishing points and 30-blade tungsten carbide burs. The smoothest surfaces for Alert composite were evident with the 30-blade tungsten carbide burs.
