Influence of Enzymatic Catalysis and Reduced Application Time on Enamel Chemical and Structural Changes Induced by In-Office Bleaching
Objectives: This study evaluated a bleaching strategy combining horseradish peroxidase (HRP) and a polymeric scaffold with 35% hydrogen peroxide, compared with a conventional in-office bleaching protocol. Methods: The study was conducted in two experimental phases. In Phase I, enamel from five sound human premolars was...
