This study is a randomized clinical trial, divided mouth and double blind, in which 40 patients were selected, totaling 80 teeth. The groups were divided as to the restorative treatment in FBF and FZ. The criteria for post-operative sensitivity (SPO), retention, staining, and marginal integrity (IM) were then evaluated for 1 and 6 months by a blind examiner, unconnected to the operator. Data were tabulated in the Microsoft Excel® 2013 program and were analyzed using the Bioestat 5.3 program, using the McNemar test for repeated measures, and Fisher’s exact test for the same period (p <0.05). In relation to IM, the FZ resin showed better results (p = 0.05). In the staining and retention criteria, there were no statistically significant differences (p = 1.00). In the evaluation of SPO, there was no statistical difference when comparing FZ in different periods (p = 0.63), as well as FBF (p = 0.37). Therefore, the FZ resin showed better results in the marginal integrity criterion, however, in the other criteria there was no statistically significant difference.
