Abstract

Background: The purpose of this in vitro study was to evaluate the effect of finishing/polishing procedures on color stability of three restorative materials: Nano-hybrid resin composite (NRC), silver glass ionomer cement (SGI), and resin-modified glass ionomer cement (RMGI) exposed to different staining of energy drinks: Barbican, Bison, and Red bull.

Highlights

  • The purpose of this in vitro study was to evaluate the effect of finishing/polishing procedures on color stability of three restorative materials: Nano-hybrid resin composite (NRC), silver glass ionomer cement (SGI), and resin-modified glass ionomer cement (RMGI) exposed to different staining of energy drinks: Barbican, Bison, and Red bull

  • The color difference ΔE* between final and initial values after exposure to different staining of energy drinks was unacceptable for all restorative materials tested with the exception of the resin composite

  • The null hypothesis was rejected, as there was a difference in color stability of the finishing/polishing procedures of different restorative materials exposed to different staining of energy drinks

Summary

Introduction

The purpose of this in vitro study was to evaluate the effect of finishing/polishing procedures on color stability of three restorative materials: Nano-hybrid resin composite (NRC), silver glass ionomer cement (SGI), and resin-modified glass ionomer cement (RMGI) exposed to different staining of energy drinks: Barbican, Bison, and Red bull. Dental esthetic is desired by both adolescents and parents, and the advent of tooth-colored restoratives material has been indispensable for this purpose. Even dentists prefer to use tooth-colored restorative materials, which have different physical properties, and shades compared to non-aesthetic restorative materials such as amalgam [4]. These restorative materials to be clinically successful are required to have long-term continuity, a quality which is strongly influenced by the intrinsic characteristics of the materials and by the environment to which they are exposed [5]. Other factors such as low pH due to acidic foods and drinks may influence the material's mechanical and physical characteristics [7]
