Enzymatically Driven Mineralization of a Calcium-Polyphosphate Bleaching Gel.

ABSTRACT: To examined alkaline phosphatase enzyme (ALP) activity and the effects of incorporating it in the thickener solution of a hydrogen-peroxide-based bleaching gel containing calcium-polyphosphate (CaPP) on the orthophosphate (PO₄^3-) levels, bleaching effectiveness, and enamel microhardness. ALP activity was assessed at different pH levels and H₂O₂ concentrations, and in H₂O- and Tris-based thickeners. Circular dichroism (CD) was used to examine the ALP secondary structure in water-, Tris-, or H₂O₂-based mediums. The PO₄^3- levels were evaluated in thickeners with and without ALP. Enamel/dentin specimens were allocated into the following groups: control (without bleaching); commercial (Whiteness-H
