From: Synergistic strategy of riboflavin and lipoids to bioengineer resin dentin hybrid layer
Representative confocal laser microscopy images taken at the resin dentin interface for all experimental groups. The resin-dentin interface formed by the (A-B) control adhesive system revealed the occurrence of commonly seen resin tags. The resin permeated the dentin, forming thick hybrid layers in both (3D-E) RFLi0.5%/0.25% and (3 F) RFLi0.5%/0.5% groups modified adhesives. None of the (C) RF0.5% or (D-E) RFLi0.5%/0.25% (gaps seen between resin tags due to mineral precipitation inside the interface have been identified with white arrows) and (F) RFLi 0.5%/0.5% groups depicted resin-dentin interface gaps. The creation of a hybrid layer containing resin tags was detected in all specimens (HL identified with white arrows), with the length of the tags being more prominent in (J) RFLi0.5%/0.5% and (3I) RFLi0.5%/0.25% groups adhesives as compared to (Fig. 3G; arrow represents the direction of resin tags) control, and RF0.5% groups (H; arrow pointing towards hybrid layer); (K-L) lateral angles of RFLi0.5%/0.5% groups indicating a comprehensive penetration of adhesive. (red rhodamine dye within adhesive and resin tags; dentin is represented as green fluorescence; RT = resin tags; HL = hybrid layer).
