The purpose of this study was to asses the shear bond strengths of 3 types of glass
ionomer cement and 1 type of composite resin to dentinal surface with or without ZOE
pretreatment. 80 extracted tooth specimens are divided into two groups ; the control
group (40 specimens) is not treated with ZOE and the other(40 specimens) is ZOE
pretreated during 24 hours before bonding procedure.
Shear bond strengths were measured with universal testing machine (Instron, Model
4301) and statistically processed by ANOVA and t-test.
The results were as follows :
1. Bond strength of the ZOE treated experimental group showed lower than the
control group, except chemical cured glass ionomer cement (p<0.05).
2. After ZOE surface treatment, the bond strength of composite resin was superior
than glass ionomer cement and all experimental group was decreased (p<0.05).
3. It has nothing to do with ZOE surface treatment, that chemical curing glass
ionomer cement was showed lowest bond strength.
