Design outcomes
Primary
| Measure | Time frame |
|---|---|
| It is expected to find a 10% decrease in retention criteria, in restorations where a solvent evaporation of 5 seconds was carried out, compared to the restorations where a solvent evaporation of 25 seconds was carried out, evaluated by means of the criteria of clinical evaluation of the International Dental Association (FDI), at 12 months | — |
Secondary
| Measure | Time frame |
|---|---|
| It is expected to find a 20% increase in criteria 3 and 4 (clinically satisfactory and clinically unsatisfactory) of marginal adaptation in restorations where a solvent evaporation of 5 seconds was carried out, compared to the restorations where a solvent evaporation of 25 seconds was carried out, evaluated by means of the criteria of clinical evaluation of the International Dental Association (FDI), at 12 months;It is expected to find a 20% increase in criteria 3 and 4 (clinically satisfactory and clinically unsatisfactory) of marginal staining in restorations where a solvent evaporation of 5 seconds was carried out, compared to the restorations where a solvent evaporation of 25 seconds was carried out, evaluated by means of the criteria of clinical evaluation of the International Dental Association (FDI), at 12 months | — |
