Adhesive-based protective strategies for enamel cracks during in-office bleaching and their effect on hydrogen peroxide penetration
Abstract Objectives To evaluate hydrogen peroxide (HP) penetration in teeth with enamel cracks and to investigate if adhesive-based strategies can reduce its permeability without compromising bleaching efficacy (BE). Materials and methods Fifty human premolars ( n = 10 per group) were allocated into five groups: unblea...
