Kinetics of calcium loss during incubation of enamel slabs for 120 s with and without application of different preparations in situ. Physiological 30 min pellicles (without rinse) and specimens without pellicle served as controls. In summary the erosion-preventive effect of fluoride was confirmed and could not be achieved by the calcium phosphate and apatite based products. Please note the different scale; n = 8 subjects; n = 24 enamel samples per subgroup; mean values ± standard deviation.
