Evaluation of the Anticaries Efficacy of Dentifrice Formulations Using an In-situ Model

Evaluation of the Anticaries Efficacy of Various Dentifrice Formulations Using an In-situ Model

The primary objective is to compare the remineralization and demineralization inhibition potential of early subsurface carious lesions in enamel in situ after rinsing with six different aqueous slurries of toothpaste formulations.
