AIM: This study evaluates marginal sealing ability of currently available three self-etching adhesives in class V micro fill composite restorations. Materials and methods: Forty five human central incisors, divided in to three groups and class V cavities were prepared on the facial surface of teeth with occlusal margin in enamel and gingival margin in dentin/cementum. The cavities were restored with microfill composite in two increments using three different adhesives, Ader prompt (3M Dental products), AdheSE (Ivolar Vicadent) and I-Bond (Heraeus Kulzer). Each group containing fifteen teeth were subjected to thermocycling and dye penetration. The teeth were mlunted and sectioned buccolingually with a hard tissue microtome, the two sections from earch tooth obtained from the both mesial and distal acute angles of the cavity preparation, examined under stereomicrscope. The values were analyzed with Chi-Square test and Fisher exact. Results: The results show less leakage in enamel and dentin margin for AdheSE. This is significantly less than Adper Prompt an IBond which showed no statistically significant difference. Conclusion: At enamel and dentin/ Cementum margins, two step self etch adhesive AdheSE performed better than one step self etch adhesives Adper Prompt and I-Bond
