Dental Bleaching Techniques: Hydrogen Peroxide Application vs Laser. Which is More Efficient?

Abstract

Teeth whitening is a clinical procedure that can be done in many ways usually using gels with carbamide or hydrogen peroxides. The main objective of this study is to compare two methods of teeth whitening: conventional (with 40% hydrogen peroxide gel) and laser method (with 45% hydrogen peroxide gel activated by diode laser). We analysed two groups of 10 patients, one for each method. The results lead to the conclusion that hydrogen peroxide activated by laser seems to be more efficient but it also brings more dental hypersensitivity at the end.
