Anticaries potential of a stabilized stannous fluoride/sodium hexametaphosphate dentifrice.

The objective of this research was to evaluate the anticaries potential of stabilized stannous fluoride and sodium hexametaphosphate dentifrice using a series of laboratory studies. In a study of fluoride uptake into demineralized enamel, the stannous fluoride/sodium hexametaphosphate dentifrice exhibited fluoride uptake comparable to the clinically proven stannous fluoride and silica dentifrice. Under lesion progression pH-cycling conditions, the stabilized stannous fluoride/sodium hexametaphosphate dentifrice was shown to protect teeth against lesion initiation and progression almost completely, and was comparable to conventional, clinically proven dentifrices. This series of well-controlled and validated in vitro studies demonstrates the anticaries potential of the stabilized stannous fluoride/sodium hexametaphosphate dentifrice. These in vitro results suggest that the stabilized stannous fluoride/sodium hexametaphosphate dentifrice may provide enhanced anticaries performance relative to a sodium fluoride control dentifrice. These results are reflective of the clinical benefits previously reported for stabilized stannous fluoride/sodium hexametaphosphate dentifrices.
