The purpose of this study was to evaluate the effects of various etching time that
affect to the bonding strength between glass ionomer cement and composite resin.
Two glass ionomer cements were divided into 4 groups according to 4 various etching
time each other.
Total 80 specimens were uniformly made and tested for the bonding strenght between
glass ionomer cement and composite resin by Instron.
The seperation force was recorded from the composite resin to the glass ionomer
cement block for each specimens.
The results were as follows.
1. Etching time affects the bonding strength between glass ionomer cement and
composite resin.
2. In Shofu glass ionomer cement, the 3 group, 30sec etching group was greater than
any other groups and significant differences were statistically demonstrated when
compared to the 1 group, non-etching group.(p<0.05)
3. In GC glass ionomer cement, the 4 group, 60sec etching group, was greater than
any other groups and significant differences were statistically demonstrated when
compared to the 1 group, non-etching group.(p<0.05)
