Design outcomes

Primary

MeasureTime frame
The clinical effectiveness of the restorations will be determined immediately after completion of the restoration and at 3, 6, 12, and 24 months by assessing loss of retention, marginal integrity, marginal pigmentation, presence of lesion surrounding the restoration and postoperative sensitivity (USPHS modified). The Friedman test will be used to statistically analyze the rankings of the items considered for the clinical evaluation of the restorations (? = 5%).—

Secondary

MeasureTime frame
Evaluations 6 months (quality of restoration), 12 months (quality of restoration) and 24 months (quality of restoration) will be carried out.The Friedman test will be used to statistically analyze the rankings of the items considered for the clinical evaluation of the restorations (? = 5%).—
