Fluoride-Releasing Self-Etch Adhesives Create Thick ABRZ at the Interface

Figure 1

Illustrations explaining the formation of acid-base resistant zone (ABRZ) with fluoride-free self-etch adhesive (a) and fluoride-releasing adhesive (b). Self-etch adhesives create an ABRZ beneath the hybrid layer (H); however, the fluoride-releasing adhesive creates a thicker ABRZ than the fluoride-free adhesive. B: bonding resin; D: dentin; R: resin composite.
