Effect on the bond strength between composite resin and glass ionomer cement.
Ann King Edward Med Uni Jan ;13(1):16.

Glass ionomer cements are tooth-coloured materials that bond chemically to dental hard tissues and release fluoride for a relatively long period. Glass ionomer is the ideal radiopaque liner for use under all types of composites. It bonds to dentin, reduces microleakage enhances the bond strength of composite.
