From: Synergistic strategy of riboflavin and lipoids to bioengineer resin dentin hybrid layer
In the backscattered SEM images of (A) control group, which is the adhesive without riboflavin and lipoid, a significant amount of silver was deposited along the resin-dentin interface and within the dentinal tubules. The (B) RF0.5% adhesive groups displayed a slightly lower amount of silver deposition as observed in the resin-dentin interface. As for (C) RFLi0.5%/0.25% and (D) RFLi0.5%/0.5% groups were concerned, no silver deposition is observed in the resin-dentin interfaces; (E) commercial control adhesive.
