Adding casein phosphopeptide-amorphous calcium phosphate to sports drinks to eliminate in vitro erosion

Abstract

Purpose: Enamel erosion can occur with frequent consumption of sports drinks. The purpose of this study was to determine a minimal concentration of casein phosphopeptide-stabilized amorphous calcium phosphate (CPP-ACP) which when added to a sports drink would eliminate such erosion in vitro. Methods: Human enamel specimens were immersed in: (1) the sports drink Powerade; (2) Powerade plus 4 concentrations of CPP-ACP (0.063%, 0.09%, 0.125%, 0.25%); or (3) double deionized water. Windows of test and control enamel were profiled, and the enamel surface characteristics were examined under scanning electron microscopy (SEM). Results: The pH of test solutions increased and the titratable acidity d..
