Abstract
The purpose of this study was to compare shear bond strength of composite resin using several detin bonding agents and light cured glass ionomer cement(Fuji II LC)
40 Bovine primary anterior teeth were used for this experiment. Labial surface of teeth were flattened. It were divided into four groups. Each group was composed of 10 teeth. The material used for this experiment were Scotchbond
Multipurpose-Z-100,
Allbond 2-Aelitefil, Gluma-Pekalux, light cured glass ionomer cement(Fuji II LC).
Each of the materials was applied to the exposed surfaces of 10 teeth by insertion into a cylindrical shaped matrix which is 3mm diameter and 3mm in height.
The completed specimens were stored at 37℃ under 100% humidity for 24 hours : the shear bond strength of each material to dentin surface were measured with INSTRON universal testing machine.
@ES The results were as follows :
@EN 1. Shear bond strength to dentin surface increased in order of ligt cured glass ionomer cement(Fuji II LC), Gluma, Allbond 2, Scotchbond Multipurpose.
2. Between shear bond strength of light cured glass ionomer cement(Fuji II LC) and Allbond 2, there was statistical significace(p<0.05)
3. Between shear bond strength of light cured glass ionomer cement(Fuji II LC) and Scotchbond Multipurpose, between shear bond strength of Gluma and Scotchbond Multipurpose, there was statistical significance. (p<0.01)
The shear bond strength of dentin bonding agents were higher than light cured glass ionomer cement. Te reason is that materials and quality of dentin bonding agent were enhanced. Further investigation is necessary to improve shear bond strength
of
light
cured glass ionomer cement.
