Sažetak
Composite materials are increasingly being used in anterior aesthetic restorations. In this indication not only color and translucency, but also surface gloss is of paramount importance. The purpose of this study was to determine the changes in surface gloss of different composite materials after simulation of mechanical ageing mechanisms. Twelve specimens were fabricated for each material and polished with 120-, 220-, 500-, 1200-, 2400- and 4000- grit SiC abrasive paper, respectively. Gloss measurements were made with a glossometer (Novocurve) prior to testing procedures. Specimens were subjected to simulated toothbrushing with an electrical toothbrush while being immersed in toothpaste. Surface gloss measurements were made subsequently. Surface gloss of all the materials was affected by simulated toothbrushing and the decrease of gloss was material dependent. Artificial materials available nowadays try to mimic natural enamels’ appearance without reaching a complete success. New developments in nanotechnology, however, let us to imagine that in the future more tooth-like materials could be developed which will present better optical properties and allow enhanced esthetic outcomes.
