  • The purpose of this study was to compare the effect of the hemostatic agent containing aluminum chloride with hemostatic agent containing ferric sulfate on the shear bond strength of resin-modified glass ionomer cement(RMGIC) to dentin in primary tooth. Twenty extracted non-carious human primary teeth were collected in this study. The specimens were cut to expose dentin and polished. The specimens were randomly seperated into 3 groups for treatment; group I: polyacrylic acid(PAA), RMGIC; group II: aluminum chloride, PAA, RMGIC; group III: ferric sulfate, PAA, RMGIC Ten specimens from each group were subjected to shear bond strength test. The mean shear bond strength of each group was as follows: 10.07 ± 1.83 MPa in Group I, 7.62 ± 0.78 MPA in group II, 5.23 ± 0.78 MPa in group III. There were significant differences among all groups(p < 0.001). In conclusion, both aluminum chloride hemostatic agent and ferric sulfate hemostatic agent decreased the shear bond strength of RMGIC to dentin. And ferric sulfate hemostatic agent decreased the shear bond strength of RMGIC more than the aluminium chloride hemostatic agent.
