An in vitro Evaluation of Microleakage of Three Different Self-Etch Adhesives with Ethanol, Acetone and Water as Solvents

Abstract

ABSTRACT Purpose The aim of this study is to evaluate and compare the microleakage of three different self-etch adhesives with ethanol, acetone and water as solvents. Materials and methods Standardized class V cavities were prepared on both facial and lingual surfaces of 60 caries-free human premolar teeth. The teeth were divided in three groups and different self-etch adhesives (OptiBond All in One, Tetric N Self-Etch, Adper Easy One) were applied according to manufacturer's instructions. The samples were then restored with composite and subjected to thermocycling. Later, the teeth were stained with methylene blue, sectioned and measured for microleakage under stereomicroscope. Results This study showed that at the occlusal margin and gingival margins, the preparations treated with OptiBond all in one showed significantly less leakage than the other groups. Enamel margins provided better marginal sealing than dentin/cementum margins. Conclusion The study demonstrated that OptiBond All in One bond had a better sealing ability at both occlusal and gingival margins compared with the other adhesives used.
