-Abstract-
For the purpose of comparing the bond strengths of some tooth adhesive restoration
materials on primary enamel and dentin. 4 kinds (7 brands) of restorative materials
including a composite resin (Z 100), a conventional glass ionomer cement (Chem-Flex).
2 brands of resin-modified glass ionomer cements (Fuji II LC-I, Vitremer, and 3 brands
of compomers(Dyract AP, F2000, Compoglass) were investigated using UTM for
measuring the shear bond strengths. Additionally the failure modes were examined by
histologically observing the fractured surfaces of each specimen. The following results
were obtained.
1. The shear bond strengths of Z 100 to the primary enamel were higher than those
of other experimental materials except Fuji II LC-I, which significantly higher bond
strength than Chem-Flex of Vitremer(p<0.05).
2. The shear bond strengths of Z 100 to the primary dentin were higher than those of
other experimental materials except Dyract. AP and Fuji II LC-I both of which showed
significantly higher shear strength than Chem-Flex or Vitremer(p<0.05).
3. The shear bond strengths of all restorative materials except Dyract AP showed
relatively higher values to enamel surface than to dentin surface. In Dyract AP, the
reverse was true significantly.
4. All materials examined showed cohesive failures except some Chem-Flex and
Vitremer, which showed adhesive failures.
