Design outcomes
Primary
| Measure | Time frame |
|---|---|
| It is expected that the color difference, measured by the CIEDE2000 (International Commission on Illumination, Color Difference 2000) formula, with its measurement value ?E00, will be less than 1.8 for both resins used. This evaluation should be performed immediately and during each follow-up period, comparing the color of the resins with that of the tooth substrate in its middle third | — |
Secondary
| Measure | Time frame |
|---|---|
| The expected finding is a 10% increase in criteria 3 and 4 (clinically satisfactory and clinically unsatisfactory) in the surface gloss of restorations made with Vittra Unique resin, compared to restorations where Omnichroma resin was used, as evaluated by the World Dental Association (FDI) clinical evaluation criteria at 12 months | — |
