Effect of Airborne Particle Abrasion on Microtensile Bond Strength of Total-Etch Adhesives to Human Dentin

Figure 1

Distribution (%) of failure mode in experimental groups after 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; Type 4: cohesive fracture in the composite restoration.
