Objectives: The aim of this study was to compare the microshear bond strength (muSBS) of various adhesive systems to dentin. Materials and Methods: In this in vitro experimental study, 60 sound human third molars were divided into four groups. Dentin discs were prepared of middle-third dentin measuring 4 mm in diameter and 2 mm in thickness. Dentin surfaces were bonded with one of the four types of adhesives: (A) Single Bond (3M ESPE), Scotchbond Universal (3M ESPE) in etch and rinse (B) and self-etch (C) modes and (D) Clearfil SE Bond (Kuraray Noritake Dental). After the application of adhesive systems according to the manufacturers' instructions, composite cylinders (Vit-l-escence) were bonded to dentin surfaces. The muSBS test was performed using a universal testing machine at a crosshead speed of 1 mm/min. Data were analyzed with one-way ANOVA and Tukey's test (alpha=0.05). Results: The muSBS was the highest in self-etch Scotchbond Universal (15.8+/-6.08 MPa) followed by Clearfil SE Bond (15.24+/-4.6 MPa), etch and rinse Scotchbond Universal (11.68+/-4.07MPa) and Single Bond (11.24+/-3.74 MPa). A significant difference was only found between Single Bond and etch and rinse Scotchbond Universal groups (P=0.04). Conclusion: Based on the results of this study, application of Scotchbond Universal in self-etch mode provides a reliable bond to dentin.
