摘　　要：比较第七代自酸蚀粘结系统Ibond涂布牙本质表面后3种不同的静置时间对其剪切强度的影响。选用人前磨牙96颗制成96个牙本质试件,Ibond按涂布粘结剂后不同的静置时间15s、30s、45s分为A、B、C三组进行树脂粘结修复,然后测试各组的剪切强度(SBS)。实验结果表明,对健康牙本质而言,15s静置时间可能已达到与静置30s、45s相当的剪切强度。To compare the effect of different treating times on the shear bond strength （SBS） of Ibond. 96 dentine speci- mens obtained from 96 human premolars were randomly divided into three groups. The specimens were treated with Ibond for three different time： 15s, 30s and 45s. Then the shear bond strength were examined after the resin covered. The SBS of the three groups was not significantly different. 15s may be enough to obtain the SBS needed for healthy dentine. s
