Context: The development of Universal adhesives has simplified the adhesive protocols in dentistry. Contact angle of adhesives are indicative of bonding ability and can predict longevity of the restoration. Aims: To compare the contact angles of three different universal adhesives and influence of prior acid etching on their contact angles. Materials and Methods: 36 caries-free intact extracted human mandibular molars were used. Two sections parallel to the occlusal surface were made beneath the dentin–enamel junction to obtain 2mm thick superficial dentin slices.Three adhesive systems were usedSingle Bond Universal (3M ESPE, St Paul, MN, USA), Solare Universal Bond (GC Corporation, Tokyo, Japan) and Tetric N Bond Universal adhesive (Ivoclar Vivadent). Measurement of static contact angle θ* with 1.0 µL droplets of liquid adhesives, was performed by the sessile drop method using Rame Harte Goniometer. Statistical analysis used: One-way ANOVA analysis followed by post hoc Tukey test to compare contact angles among the groups with respect to both etched and unetched dentin. Independent t- test was used to compare the contact angles of etched and unetched dentin of the respective adhesive groups. Results: Single Bond Universal exhibited highest contact angle followed by Tetric N Bond Universal and least contact angle was shown by Solare Bond Universal. Prior acid etching had no significant influence on the contact angle of the adhesives. Conclusions: Solare Bond Universal showed the best wettability followed by Tetric N Bond Universal and Single Bond Universal. Prior acid etching did not improve the wettability.
