(a) SEM micrograph of a replica of human enamel conditioned with G-Bond Plus (GC). The adhesive was dissolved in acetone for 12 h in a rotator. The replica of droplets is depicted throughout the surface. Original magnification = 10,000X. (b) SEM micrograph of the adhesive-dentin interface formed with G-Bond Plus (GC) in self-etch mode. This particular area corresponds to the top of the hybrid layer below the adhesive layer. The asterisks depict residual droplets. Original magnification = 10,000X. (c) TEM micrograph of the adhesive-dentin interface formed with the G-Bond Plus (GC) in self-etch mode. H – hybrid layer; Int – intertubular dentin; Arrows – residual droplets The dotted lines mark the hybrid layer thickness; Ovals – hydroxyapatite crystallites visible inside the hybrid layer denoting mild decalcification; Asterisks – residual smear layer.
