Introduction: The ability to seal margins is considered as one of the best predictors for the long-term success of bonded restorations. The aim of this study was to compare microleakage in occlusal and gingival margins between cavities filled with self-adhesive flowable and conventional flowable composites using dye penetration. Composite restorations were bonded with self-etch, total etch and universal adhesives. 
Materials & Methods: In this in vitro study, 32 extracted human premolars for orthodontic  purpose were included. Class V cavities (
3×3×1.5 mm) were prepared on the facial and lingual surfaces of each tooth.  The teeth were randomly divided into four equal groups based on the type of material: Single Bond 2 (3M ESPE), Clearfil SE Bond (Kuraray, Tokyo,Japan), Universal Scotch Bond(3M ESPE), and  Vertise Flow (Kerr Corp). Bonding agents were applied according  to the manufacturer instructions. Then the cavities of the first three groups were restored with Filtek Flow (3M ESPE,USA). In addition, the teeth were  thermocycled for 30 seconds and 1000 cycles at 5°-55°C.  Microleakage was evaluated using a stereomicroscope (X 40). Specimens were subjected to a dye leakage test. Data were  analyzed using Kruskal- Wallis and Mann-Whitney U tests. 
Results:   Significant difference was observed in microleakage among four groups in both occlusal and gingival levels (p≤0.05).No significant difference was found regarding microleakage between Vertise Flow, and Etch-and-rinse and Universal groups.
Conclusion:  Vertise Flow is a useful material with  adequate  marginal seal.
