Primary
| Measure | Time frame |
|---|---|
| When the study reach the results phase, it will be evaluated the increase in the number of losses of dental restorations in the period of two years, verified by periodic visual clinical examination based on the statement of difference of at least 25% in the amount of remaining restorations in the different groups. | — |
Secondary
| Measure | Time frame |
|---|---|
| When the study reach the results phase, it will be evaluated the increase in the number of dental restorations with marginal pigmentation in the period of two years, verified by periodic clinical visual examination based on the statement of difference of at least 25% in the amount of stained restorations in the different groups. When the study reach the results phase, it will be evaluated the increase in the number of dental restorations with dentin hypersensitivity in the period of two years, verified by periodic clinical examination based on the statement of difference of at least 25% in the amount of restorations with dentin hypersensitivity in the different groups. When the study reach the results phase, it will be evaluated the increase in the number of dental restorations with secondary caries in the period of two years, verified by periodic radiographic examination based on the statement of difference of at least 25% in the amount of restorations with secondary caries in the different groups. | — |
