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
During the previous decade, resins were widely used in the restoration of posterior teeth, as it was found that wear occurs in the abrasive and adjacent section of resin-based restorations, while in the marginal areas, marginal leakage was observed.
