This in vitro study evaluated the shear bond strengths of five adhesive systems bonded to dentin with and without simulated physiologic hydrostatic pressure. To simulate pulpal pressure, bonding procedures were done on extracted teeth connected to a hydration apparatus. Bond strengths were significantly less for each adhesive system under simulated physiologic conditions. Amalgambond had significantly higher bond strengths than Clearfil Photo Bond, Gluma, Scotchbond 2, or Tenure, either with or without simulated pulpal pressure.
这项体外研究评估了五种粘结系统在有和没有模拟生理静水压情况下与牙本质粘结的剪切粘结强度。为了模拟牙髓压力，粘结操作在与水合装置相连的离体牙上进行。在模拟生理条件下，每种粘结系统的粘结强度均显著降低。无论有无模拟牙髓压力，Amalgambond的粘结强度均显著高于Clearfil Photo Bond、Gluma、Scotchbond 2或Tenure。
