Background. For successful restoration, it is necessary to minimize the microleakage between dentin and the composite material.
Objectives. The purpose of this study was to evaluate the microleakage of 2 different resin cements (self-adhesive and conventional) on dentin treated with acid, sodium hypochlorite (NaOCl), the acid–NaOCl mixture, the erbium-doped yttrium aluminum garnet (Er:YAG) laser, and their combination.
Material and Methods. Seventy dentin specimens were divided into 7 groups (n = 10) according to the surface treatment. Then, the specimens were divided into 2 subgroups (n = 35) according to the resin cement used during cementation with prepared composite resin blocks 5 mm × 11 mm × 3 mm: self-adhesive resin cement or conventional resin cement. Microleakage was scored and recorded at the occlusal and gingival levels, along the resin–dentin interfaces. The data was analyzed with the use of univariate analysis of variance (two-way ANOVA) and the Kruskal–Wallis test for both resin subgroups.
Results. The obtained results revealed that self-adhesive resin cement and conventional resin cement showed similar microleakage. Etching with sodium hypochlorite, the Er:YAG laser, the acid–NaOCl mixture, and their combination resulted in microleakage comparable to that achieved in acid etching, which is the conventional method of surface treatment.
Conclusion. Microleakage exhibited by self-adhesive resin cement was similar as in the case of conventional resin cement.
