Abstract

The purpose of this study was to evaluate microleakage of two different adhesive systems between resin composite restorations and cavity walls. The experiment was conducted on 12 intact human third molars, extracted for orthodontic reasons, sectioned at the cemento-enamel junction to provide crown segments. The cavities were prepared in the occlusal surfaces. The samples were divided into two groups, six samples in each. Restorations were made with the resin composite “Tetric Ceram” (Vivadent, Schaan, Liechtenstein) and two different self-etch adhesive systems: in one group two-step self-etch AdheSE (Vivadent, Schaan, Liechtenstein), and in the other single-step self-etch Xeno III (DeTrey, Konstanz, Germany). Microleakage was measured by two different methods, fl uid transport model and dye penetration. The results using fl uid transport model showed no statistically signifi cant difference between two groups of samples (p=0,7488). Marginal leakage measured using dye penetration technique method showed statistically signifi cant higher degree of marginal leakage (p=0,002) in the group where Xeno III was used.
