Fig. 1From: Effect of Bioglass 45S5 air-abrasion on dentin bonding: evaluation of microtensile bond strength and confocal microscopyConfocal microscopy showing the bonding interface with adhesive layers (rhodamine-B) and dentin immersed in fluorescein. G1 inter–diffusion zone is continuous with resin tags; G2 infiltration of resin tags (T) and inter–diffusion zone (hybrid layer); G3 greater diffusion in adhesive layer; G4 small and many resin tags (T) and the hybrid layer with a good inter–diffusion zoneBack to article page
