Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. Macroscopic characterization (presence, frequency, and severity) of white spot lesions at baseline, after 6 months, and after 12 months of orthodontic treatment. The severity of disease will be rated according to Gorelick's classification: Grade 0: no visible white spot lesions on clinical investigation Grade 1: minor white spot lesions Grade 2: severe white spot lesions Grade 3: white spot lesions with cavitation 2. Determination of fluorescence, size and lesion depth and the bacterial acitivity of white spot lesions by means of quantitative light-induced fluorescence measurement (QLF) at baseline, after 6 months, and after 12 months of orthodontic treatment. | — |
Secondary
| Measure | Time frame |
