An appropriate bond between glass‑ionomer and the superficial
resin materials is very important for the success of sandwich
technique. The aim of the present in vitro study was to evaluate the
effect of three surface treatments of conventional glass‑ionomer on
its shear bond strength to giomer
The aim of this in vitro study was to evaluate the
microleakage on the gingival margin located below the cemento-enamel
junction of class II composite restorations (CR ,Tetric-ceram,Vivadent)
applied with a 5th generation bonding material (Excite,Vivadent) and to
compare it with that seen in open sandwich restorations using a
nanoionomer material (OST ,Ketac N100,3M) and a composite material
(Tetric-ceram).
