Design outcomes
Primary
| Measure | Time frame |
|---|---|
| No significant changes (p greater than 0.05) in the color of bovine dental enamel after evaluation of the fragments removed from the device through Easyshade (VITA®, Bad Säckingen, Germany) and use of the CIE L*a*b* system (Commission Internationale de l'Éclairage). The results obtained will be evaluated according to the normality of the values found and the most appropriate statistical test | — |
Secondary
| Measure | Time frame |
|---|---|
| Lack of significant changes (p greater than 0.05) in Knoop microhardness of bovine dental enamel after evaluation of the fragments removed from the device through the Micro Hardness Tester HMV-2 (Shimadzu®, Tokyo, Japan). The results obtained will be evaluated according to the normality of the values found and the most appropriate statistical test;No significant changes (p greater than 0.05) in the surface roughness of bovine dental enamel after evaluation of the fragments removed from the device through the Surftest SJ-201P (Mitutoyo®, Kanagawa, Japan). The results obtained will be evaluated according to the normality of the values found and the most appropriate statistical test;No significant changes (p greater than 0.05) in the brightness of bovine dental enamel after evaluation of the fragments removed from the device through the Micro-Gloss 45 ° gloss meter (BYK Gardner, Gerestried, Germany).
