Statement of Problem The choice of adhesive application methods could affect the microleakage of self‐etch adhesives. Purpose To evaluate the effect of acid‐etching, doubling adhesive application time, doubling adhesive coating, and rebonding agent application on microleakage of self‐etch adhesives in C lass V cavities. Materials and Methods Seventy human third molars with C lass V cavities assigned to five groups according to different adhesive application protocols for the three dentin adhesives ( C learfil S 3 B ond, Kuraray Medical, Okayama, Japan; O ptibond A ll‐in‐ O ne, Kerr Corporation Orange, CA, USA; G ‐ A enial B ond, GC Corporation, Tokyo, Japan): group 1, manufacturer's recommendations; group 2, prior acid‐etching of cavities; group 3, double application time; group 4, two consecutive coats of the adhesives; group 5, rebonding application on restoration margins. After bonding, the cavities were filled with a resin composite ( F iltek S upreme XT , 3M ESPE Dental Products, St. Paul, MN, USA). The teeth were thermocycled, and the specimens were examined for microleakage using methylene blue as a marker. Results For C learfil S 3 B ond and O ptibond A ll‐in‐ O ne, microleakage in groups 2 and 5 were significantly lower than other groups' enamel margins. In groups 1, 2, 4, and 5, C learfil S 3 B ond exhibited significantly more leakage than the other dentin bonding agents in dentin margins. Microleakage was significantly higher on dentinal margins compared with the enamel margins for C learfil S 3 B ond in all of the groups. O ptibond A ll‐in‐ O ne showed significantly lower microleakage in dentin margins in all groups except groups 2 and 5. Conclusion Acid‐etching usually promoted the reduction of microleakage in enamel margins. On the other hand, rebonding application usually contributed to the reduction of microleakage more than other methods in enamel and dentin margins.Clinical Relevance Acid‐etching or rebonding application may contribute to reduction of microleakage of all‐in‐one self‐etching adhesives.
