Analysis Of The Chemical Modification Of Dental Enamel Submitted To 35% Hydrogen Peroxide “In-Office” Whitening, With Or Without Calcium

Abstract Purpose The purpose of this study was to evaluate changes in calcium and phosphorus content in dental enamel when subjected to “in-office” whitening for an extended time by using a 35% hydrogen peroxide solution, with and without calcium. Materials and Methods 10 human teeth, from which the roots had been removed, were embedded in epoxy resin, and their surfaces were smoothed. The specimens were divided Leia mais
