Abstract
Despite its proven efficacy, whitening with 35% hydrogen peroxide (H2O2) presents challenges related to pulp cytotoxicity, a fact clinically observed as tooth sensitivity. In a previous study, we observed that a hydrogel consisting of a highly biocompatible glass-ceramic, Biosilicate® (BioS), doped with manganese oxide (MnO2), incorporated with 6% H2O2 and irradiated with violet LED light…
