This study compared the shear bond strengths of dentin bonding systems applied to air dried and blot (moist) dried dentin. Five systems with primers possessing hydrophilic properties were evaluated. Three contained acetone. All Bond, Amalgambond, Mirage Bond and Tenure all produced significant statistical improvement in shear bond strength values when applied to moistened dentin. Mirage Bond values quadrupled. Bond strength values with Gluma were compromised by the presence of moisture. It was concluded that acetone probably facilitated deeper and more complete penetration of resin into dentin to enhance micro-mechanical retention. Amalgambond, while free of acetone is strongly hydrophilic and is known to form substantial mechanical bonding through the formation of a resin rich superficial layer of dentin (hybridization). Gluma while hydrophilic does not appear to possess the same behavioral characteristics embodied in the other systems as evidenced from lack of a bond to moist dentin.
本研究比较了应用于气干和吸干（湿润）牙本质的牙本质粘结系统的剪切粘结强度。评估了五种具有亲水性底漆的系统。其中三种含有丙酮。当应用于湿润牙本质时，All Bond、Amalgambond、Mirage Bond和Tenure的剪切粘结强度值均有显著的统计学改善。Mirage Bond的值增加了四倍。Gluma的粘结强度值因水分的存在而受到影响。得出的结论是，丙酮可能有助于树脂更深入、更完全地渗透到牙本质中，以增强微机械固位。Amalgambond虽然不含丙酮，但具有很强的亲水性，并且已知通过形成富含树脂的牙本质表层（杂交）形成大量的机械粘结。Gluma虽然具有亲水性，但似乎不具备其他系统所体现的相同行为特征，这从其与湿润牙本质缺乏粘结力可以证明。
