Study Summary

The study will evaluate and compare the potential anti-caries efficacy of a test regimen: placebo (fluoride free) toothpaste (twice daily use) plus fluoride mouthwash (once daily use), in comparison with brushing with a placebo toothpaste alone (twice daily use), to remineralize previously demineralized enamel specimens, as measured by Surface MicroHardness Recovery (%SMHR). This will be a single center, randomized, laboratory analyst blinded, placebo, four treatment, cross-over study in healthy participants. Participants will be assessed at baseline and at the beginning and end of each treatment visit to monitor clinical efficacy and safety.

Primary Outcome

SMHR test was used to assess the changes in mineralization status of enamel specimens using a Wilson 2100 Hardness tester. SMHR was performed ex-vivo and 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 re-hardening of enamel surface. % SMH recovery was calculated from indentation length (micrometer \[μm\]) of sound enamel specimen at b
