Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Fluoride Mouthwash | Participants with normal salivary flow to dry mouth were treated, in a crossover design, with two interventions: a fluoride mouthwash alone, or a fluoride mouthwash preceded by a calcium mouthwash.~Participants were randomized to determine which intervention they used in the first experimental phase; the other intervention will the tested in the second phase.~This arm refers to the use of the fluoride mouthwash: Sodium fluoride, at a concentration of 0.05% (226 parts per million (ppm) of fluoride), was used to rinse the mouth for 1 minute and expectorated. | 0 | 19 | EG000 |
| Group 2 | Calcium Mouthwash Before Fluoride Mouthwash | Participants with normal salivary flow to dry mouth were treated, in a crossover design, with two interventions: a fluoride mouthwash alone, or a fluoride mouthwash preceded by a calcium mouthwash.~Participants were randomized to determine which intervention they used in the first experimental phase; the other intervention will the tested in the second phase.~This arm refers to the use of the calcium mouthwash before the fluoride mouthwash: Calcium lactate, at a concentration of 150 millimolar, was used to rinse the mouth for 1 minute and expectorated; immediately after, a sodium fluoride rinse, at a concentration of 0.05% (226 ppm of fluoride), was used to rinse the mouth for 1 minute, and expectorated. | 0 | 20 | EG001 |
