Abstract
The aim of the current study was to evaluate the reliability of two methods [polishing with Sof-lex disks and in-office bleaching with 40% hydrogen peroxide (Opaloescence Boost)] to remove stain caused by commonly consumed beverages (tea and cola) from two resin-based restorative materials [nanohybrid composite resin (N-Fill) and resinmodified glass ionomer (Ionolux)]. Twenty disk-shaped specimens were prepared of each of the two tested resin-based restorative material (N-Fill and Ionolux) representing two main groups (I) and (II).
