Abstract: Fourteen different composites were polished in vitro with Sof-lex 3M discs. The results were examined clinically, with SEM, and profilometrically. According to the clinical study the different materials were divided into three groups. Group A consisted of five composites, that could be polished up to a fair gloss. Group B contained five composites, where only a semi-gloss could be obtained. Group C contained four products, whose surfaces remained dull after whatever polishing procedure. The SEM study affirmed these results. The products of group A showed smooth and homogeneous surfaces; hence their name: smooth-surface composites. The products of group B can be considered as classic composites. Group C contains among others the glass ionomer cements. The profilometrical study pointed out that the roughness degree of group A was three times smaller than that of group B and five times smaller than that of group C. The polishing procedure was further analysed. Polishing material, technique and time are the most important factors in the finishing of composite fillings.
