Abstract
The purpose of this study was to evaluate the bond strength between the composite resin and light - cured glass ionomer cement base/liners treated by the several methods.
The light - cured glass ionomer cement (Vitrebond / Cavalite) were injected into cavites prepared in acrylic plates.
One hundred and twenty specimens were uniformly prepared and devided into 3 groups. For the first group, primer was not applied to glass ionomer cement. For the second group, no application of primer was undertaken and light - curing procedure to
uncured glass ionomer cement surface which was covered by bonding agent was undertaken, After bonding composite resin to light - cured glass ionomer surface, the specimens were stored in 37℃, 100% humidity for 1 hour.
@ES The following results were obtained:
@EN 1. The omission of application of a primer did not produce a significantly poorer bond strength.
2. Light - curing technique to uncured glass ionomer cement which was covered by bonding agent did not produce a significantly poorer bonding strength.
3. The bond strength of Cavalite to composite resin was significantly higher than that of Vitrebond.
4. There was no significant difference between two different types of composite materials (Silux - Plus / Herculite XR) when it was applied to bond to glass ionomer cement.
