Abstract
The purpose of this study was to assess comparatively the shear bond strength on dentin of four dentin bonding agents used in conjunction with light-curing composite resins. Clearfil New Bond, Scotchbond Multipurpose Dentin Adhesive, All-Bond 2
and
X-R
Bond were applicated on labial dentin surfaces just below dentin - enamel juction of bovine incisor teeth.
After shear bond strength testing with the universal testing machine, the bonding interface of the specimens were observed under light stereomicroscope.
@ES Following results were obtained.
@EN 1. The shear bond strength was high in the order of B, C, D, A and group B Scotchbond Multipurpose Dentine Adhesive revealed greater bond strength than Clearfil New Bond and X-R Bond. (p<.001)
2. When using ANOVA and Duncan's multiple range test, there were statistical differences among the four groups, except between group B and C group D and A.
3. There was no relationship between mode of failure and shear bond strength.
