| Measure | Time frame |
|---|---|
| Main Objective: The application of the fluid with a concentration of 1.0% fluoride leads to a higher fluoride uptake than the application of a fluid with a fluoride concentration of 0.5%;Secondary Objective: 1. The application of the fluid with a concentration of 1.0 % fluoride leads to greater remineralisation than the application of a fluid with a fluoride concentration of 0.5% 2. The application of the fluid with a concentration of 0.5% fluoride is superior to placebo with respect to fluoride uptake and remineralisation.;Primary end point(s): Fluoride uptake | — |
