Primary Outcome Measures

Name	Time	Method
Retention of restorations evaluated by the FDI method in the baseline periods, after 6, 12, 18 and 24 months. The retention rates will be calculated according to the following equation: Cumulative percentage = [(PF + NF) / (PF + RR) X 100%, where PF is the number of previous failures before the current assessment, NF is the number of new failures during the current evaluation and RR is the number of restorations currently evaluated.
