Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The fracture and retention rates of restorations will be evaluated at 7 days and 6 months through direct clinical examination by two calibrated and blinded evaluators, using the FDI clinical criteria. Restorations will be classified as acceptable (scores A, B, or C) or unacceptable (scores D or E), and the cumulative failure rate will be calculated using the Kaplan-Meier method, with comparisons using the log-rank test (a = 0.05). | — |
Secondary
| Measure | Time frame |
|---|---|
| It is expected to evaluate marginal adaptation, surface texture, marginal discoloration, color stability and anatomical shape in 7 days and after 6 months, using the FDI clinical criteria, considering scores A, B or C as acceptable and scores D or E as unacceptable.;It is expected to evaluate postoperative sensitivity, presence of recurrent caries and periodontal response adjacent to the restorations in 7 days and after 6 months, through direct clinical examination and patient reports, recording the presence or absence of each condition.;It is expected to evaluate the operator's perception regarding ease of handling, material consistency, insertion control and general satisfaction immediately after each procedure, using a structured questionnaire with a 5-point Likert scale, with 1 being very bad and 5 being very good. | — |
