ABSTRACT
OBJECTIVE: To survey the immediate bond strength of the two glass ionomer cements with different pressure times.METHODS: Totally 70 teeth were prepared to expose the dentin, and then divided into the Ketac~(TM)Cem Easymix GIC glass ionomer cement group (3M group), and the TOKUSO glass ionomer cement (TOKUSO group). Each group was divided into 7 subgroups according to pressure times. The immediate tensile strengths of all specimens were measured after pressed for 5,10,15, 20, 25, 30 and 35 minutes.RESULTS: The immediate bond strengths of the two glass ionomer cements with different pressure time showed obviously significant differences (P < 0.01), which exhibited the greatest immediate bond strengths at 25 minutes after pressure. The bond strength of 25 minutes subgroup of 3M was higher than that of TOKUSO group, but the difference had no significance.CONCLUSION: Both Ketac~(TM) Cem Easymix and the TOKUSO glass ionomer cement can harvest the maximum bond strength after 25 minutes pressure.
