Materials and Methods. 30 extracted human molars were divided into three groups (n=10) to compare the adhesive “Prime&BondActive”under optimal, overly dry, and overly wet cavity moisture conditions. Class V cavities were filled with nanocomposite and polished. All teeth were thermocycled for 3000 cycles, sealed and immersed in 1% methylene blue solution for 24 hours. Consequently, teeth were sectioned and analyzed under a microscope. Dye penetration lengths were scored in millimetres and permeation degrees. Results. The results showed that self-etching universal adhesive was least permeable (lower dye penetration depths) under optimal working field conditions. During overly wet cavity moisture conditions performans decreased insignificantly. Conclusions. According to the present study there is no significant difference of microleakage using universal adhesive in class V composite restorations with different moisture level. Key words: microleakage, universal adhesive, class V composite restoration.
