Adhesive Bond Integrity of Experimental Zinc Oxide Nanoparticles Incorporated Dentin Adhesive: An SEM, EDX, μTBS, and Rheometric Analysis

Figure 3

FESEM images of resin-dentin interface showing (a) adhesive resin (AD), hybrid layer (HL), and normal resin tag (RT) formation in control samples (0% ZnO). (b) Normal resin tag formation and dentin penetration with 5% ZnO particle incorporated dentin adhesive. (c) RT formation and dentin penetration were compromised in 10% ZnO particle (few resin tags).
