European Journal of Oral Sciences, EarlyView.Abstract Hydrogen peroxide (HP) at 35% is effective for dental bleaching but may reduce enamel mineral content and induce structural changes. This study developed a bleaching‐hydrogel containing 6%HP and manganese‐oxide–doped Biosilicate (MnO_BioS), activated by violet LED, under in situ conditions.
