Shear bond strength of ceramic brackets with two bonding adhesives

The shear bond strength of two adhesives (Concise and Dyna-Plus bonding system) with one type of ceramic bracket was determined in this study. There were statistically significant differences between the bond strengths, with Concise recording higher levels than Dyna-Plus. Failure sites of Dyna-Plus were revealed at the enamel/resin, resin/resin, and resin/bracket interfaces; that of the Concise was mainly at the resin/bracket interface.
