Microleakage of three glass ionomer cement bases.

This study compared the marginal leakage in Class V restorations using three different GIC bases and a composite resin sandwich. The specimens were randomly divided into three equal groups, and the following GIC materials were used as bases: Group I: Ketac-Bond Aplicap; Group II: GC Dentin Cement; Group III: Shofu GlasIonomer Base. The results indicated less microleakage in restorations with a Shofu GlasIonomer Base while no statistical differences were noted between Ketac-Bond Aplicap and GC Dentin Cement.
