Incorporation of Calcium Polyphosphate Sub‐Microparticles in Commercial Toothpastes and Their Effects on Dental Enamel

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Dental bleaching with 35% hydrogen peroxide (HP) can cause deleterious effects on the mineral content of enamel. In this regard, remineralizing submicroparticles of calcium polyphosphate (CaPP) have been investigated for their ability to deposit calcium ions into enamel's hydroxyapatite.
