- CPP: 2.5% CPP solution; CPP + F: 2.5% CPP supplemented with 900 ppm fluoride solution; Ca: Calcium; F: Fluoride. The concentrations of total and free calcium and fluoride in solutions were measured, and the corresponding bound ion concentrations were calculated. Data are expressed as the mean ± SD. Percent of ion bound by CPP is indicated in parentheses
