Abstract
Artificial caries-softened dentin lesions in root surfaces were treated with 50% slurries of a monofluorophosphate (MFP®) dentifrice or a placebo dentifrice twice daily for ten days. Between dentifrice treatments, the lesions were kept in a remineralizing solution. Both treatments resulted in statistically significant remineralization, with the MFP dentifrice being significantly better than the placebo. Deposition of new mineral from the MFP dentifrice occurred about equally at or within the surface zone and at the deepest part of the lesion. Mineral deposition from the placebo appeared to be more uniformly distributed within the lesion.
