The tensile and shear strengths of three kinds of adhesives were not different statistically (P>0.05). Furthermore, the release of fluorin ion did not have adverse effect on the adhesive strength of FRA within three months.

• 3种粘接剂之间抗张粘接强度和抗剪粘接强度均没有统计学差异 (P >0 .；0 5 )；且在 3个月的时间内；FRA中氟离子的释放没有对FRA的粘接强度产生不利的影响。
