Shear Bond Strengths and Morphological Evaluation of Filled and Unfilled Adhesive Interfaces to Enamel and Dentine
Figure 9
(a) Scanning electron micrograph of the resin-dentin interface bonded with SB (500x). A few long and short resin tags are visible, and some of tags are seen in dentinal tubules. Continuous gap could be seen in this image (opposing arrows). RC: resin composite; AR: adhesive resin; HL: hybrid layer; D: dentin; T: tag. (b) Scanning electron micrograph of the resin-dentin interface bonded with SB (1250x). Note to the continuous gap beneath the hybrid layer (opposing arrows). RC: resin composite; AR: adhesive resin; HL: hybrid layer; D: dentin; T: tag.
