Radiopacity of resin-modified glass-ionomer restorative cements.

摘要: This in vitro study compared the relative radiopacities of three commercially available resin-modified glass-ionomer cements (Vitremer, Fuji II LC, and Photac-Fil), an experimental (V-66), two conventional glass-ionomers (ChemFil Cap II), amalgam (as control). Radiopacity was assessed densitometrically expressed as equivalent thicknesses aluminum. All were more radiopaque than enamel dentin, with exception ChemFil Photac-Fil. Apart from control material, V-66, had highest radiopacity all materials tested. Of tested, LC most Photac-Fil least. For restorative to exceed that enamel, it should be greater 1.5 mm thickness
