Design outcomes
Primary
| Measure | Time frame |
|---|---|
| After averaging the surface loss calculations per tooth site (sample area), mean tissue loss and mean standard deviation for each tooth site and total tissue loss per person are calculated over each study period. The primary analysis estimates the erosive effect of the consumption of orange juice on the outcome variable the profilometrically measured tissue loss, expressed in micrometers. | — |
Secondary
| Measure | Time frame |
|---|---|
| The secondary analysis will evaluate surface loss distribution by tooth site (occlusal, palatal, buccal, and upper / lower jaw, left/right quadrant). | — |
