Effect of different beverages and tooth brushing on some mechanical and physical properties of two different dental resin composites

Abstract

The aim of our study was to evaluate the effect of different beverages (instant coffee; Nescafe classic, red wine and cola drink; Pepsi cola); with and without brushing; on a nanohybrid ormocer (Admira fusion) and a nanohybrid dimethacrylate based composite (Grandio) concerning their: surface hardness, surface roughness, color stability, water sorption and solubility. Dental resin composite restorative materials are becomingly the most common direct restorative materials due to the increased esthetic demands. Hence the oral cavity is one of the most challenging environments, thus, these resin composite materials are subjected to a lot of challenges that might deteriorate their physical and mechanical properties.
