Abstract

Objectives: This study aims to evaluate the efficiency of experimental materials for the internal bleaching of non-vital teeth, compared to commercially available agents based on peroxides. Methods: Sixty extracted teeth divided in six groups underwent endodontic treatment followed by simulated discoloration. For each group, a different bleaching formulation was used. The dental colour was assessed by spectrophotometry. Results: According to the spectrophotometric analysis, the most effective results were achieved for groups treated with TiO2 /SiO2 /Aa and TiO2 /SiO2 with small amount of sodium perborate addition. Conclusions: Our study reveals that internal bleaching with oxidative systems is a plausible innovation..
