The Effect of Fluoride in an Experimental Dentifrice on Remineralization of Erosive Lesions In-Situ
The proposed study will evaluate the performance of fluoride delivered from a new dentifrice formulation without potassium nitrate. It will also evaluate the dose-response to fluoride by testing four dentifrices covering a range of sodium fluoride concentration.

Conditions
- Enamel Erosion
Interventions
- sodium fluoride
- no added fluoride in a silica base
Primary outcomes
- Percentage Surface Microhardness Recovery (%SMHR) Dose Response Relationship — Baseline to 4 hours
SMHR test was used to assess the changes in mineralization status of enamel specimens using a Wilson 2100 Hardness tester. SMHR was determined by measuring the length of the indentations of enamel specimens. An increase in the indentation length compared to the baseline indicates softening while decrease in the indentation length represents rehardening of enamel surface. Percent SMHR was calculated from indentation values of enamel specimens at baseline (B), after in-situ hardening (R) and after first erosive challenge (E1) using formula: \[(E1-R)/ (E1-B)\]\*100.
