Effect of Three Different Polishing Techniques on Surface Roughness and Bacterial Adhesion of Two Composite Resin

Abstract

Background and Aim: Resin composites are widely used in restorations. The adhesion of bacterial plaque to restorations depends on the surface properties and the composition of materials. As the Streptococcus Mutans has a major role in primary and secondary caries, the purpose of this in-vitro study was to examine the effect of different surface treating techniques on surface roughness and the amount of bacterial plaque adhesion on two types of resin composites.
