Effect of different finishing techniques for restorative materials on surface roughness and bacterial adhesion.

Statement Of Problem: The formation of biofilm and bacterial accumulation on dental materials may lead to the development of gingival inflammation and secondary caries.

Purpose: The purpose of this study was to examine the effect of different surface finishing and polishing methods on surface roughness and the adhesion of S. mutans bacteria to 2 new-generation indirect composite resins, 1 direct composite resin, and 1 ceramic material.
