Introduction: One of the best predictors of the long-term success of bonded restorations is the ability of marginal sealing. The aim of this study was to scale of microleakage between tooth and restoration compared. This study evaluate microleakage in occlusal and gingival margin cavity filled with self-adhesive flowable composite compared with conventional flowable composite bonded with self-etch, total etch adhesive and universal adhesive by dye penetration.
Materials & Methods: In this laboratory study, a total of 32 freshly orthodontically extracted human premolars were included in the study. Class V cavities (
3×3×1.5 mm) were prepared on the facial and lingual surface of each tooth. Teeth were randomly divided into four groups included 8 teeth based on the type of material: Single Bond 2 (3M ESPE), Clearfil SE Bond (Kuraray, Tokyo,Japan), Universal Scotch Bond(3M ESPE), Vertise Flow (Kerr Corp). Bonding agents were applied as per the manufacturer’s instructions and the cavities of three first groups were then restored with Filtek Flow (3M ESPE,USA). Teeth were then thermocycled for 1000 cycles at 5°-55°C with 30 seconds of dwell time. Specimens were subjected to a dye leakage test. Microleakage was evaluated using a stereomicroscope (X 40). Data was analysed using Kruskal- Wallis, Mann-Whitney test to assess the difference in microleakage among various adhesives.
Results: There were significant differences between the four groups in both occlusal and gingival levels in terms of microleakage (p≤0.05).
Conclusion: No significant differences in microleakage between Vertise Flow and Etch- and -rinse  and  Universal groups. Therefore Vertise Flow is a useful material with a marginal seal.
