Shear Bond Strengths and Morphological Evaluation of Filled and Unfilled Adhesive Interfaces to Enamel and Dentine
Figure 7
(a) Scanning electron micrograph of the resin-dentin interface bonded with OBSP (500x). Resin tags of the adhesive resin layer are visible. The adhesive layer thickness is not uniform 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 OBSP (1250x). Resin tags and lateral branches (arrows) of the adhesive resin layer are visible. RC: resin composite; AR: adhesive resin; HL: hybrid layer; D: dentin; T: tag.
