About this study
Official title: Evaluation of Anterior Restorations
In this study, a universal adhesive was used with different adhesive techniques (self-etch and total-etch modes) and evaluated for 18 months in three different types of composite material class III and class IV restorations according to the FDI criteria. The hypotheses tested in this study are: (1) clinical success will not differ between different composite materials and (2) clinical outcomes will not differ between different application modes of the universal adhesive.
