Microtensile Bond Strength of Etch-and-Rinse Adhesives in Different Hydroabrasion Conditionings

Figure 1

Distribution (%) of failure mode in experimental groups after the microtensile bond strength test. Type 1, adhesive fracture between adhesive agent and dentin; type 2, adhesive fracture between adhesive agent and dentin plus partial cohesive fracture in the composite restoration or dentin (mixed failure); type 3, cohesive fracture in dentin; and type 4, cohesive fracture in the composite restoration. EXC, ExciTE F DSC; ENA, ENA Bond; UNI, Scotchbond Universal; C, control group; HA/3, hydroabrasion group at 3 bar; HA/5, hydroabrasion group at 5 bar; HA/7, hydroabrasion group at 7 bar.
