Since 1984, Munksgaard and Asmussen reported using a chealating agent, EDTA,instead of phosphoric acid, to partially remove the smear layr followed by pretreatment of the dentin surface with 35% hydroxy-ethyl-methacrylate (HEMA) and 5% glutaraldehyde, to increase resin-dentin bonding strength. The development of dentin bonding agents has gone through several generations of adhesive agents. Recently, for the purpose of simplifying resin bonding, several new products were made by combining acidic conditioners such as Phenyl-P with HEMA primers to create what are called self-erching primers. All the components of these dentin bonding systems are designed in different mechanism to enhance the bonding strength, and careful observance of all the manufacturers'directions is also recommended. The effect of each component of dentin bonding systems on the tooth bonding has so far been unclear in detail.In this report, different kinds of dentine bonding systems, were used in various combinations to smear-layr-covered-dentin and polished-enamel surfaces of freshly extracted caries-free human molars and incisors to investigate the effects of the conditioners, primers and bonding agents on the tooth bonding.The results indicate that acidic conditioners are necessary for dentin bonding system, adhesive-containing primer and bonding agent might contribute to a higher bond strength.

自1984年以来，Munksgaard和Asmussen报道使用EDTA代替磷酸来部分去除牙本质表面的污垢，然后用35%的甲基丙烯酸羟乙酯(HEMA)和5%的戊二醛对牙本质表面进行预处理，以增加树脂与牙本质的粘结强度。牙本质粘结剂的发展经历了几代粘结剂。最近，为了简化树脂粘接，将苯基-P等酸性调理剂与HEMA底漆相结合，制成了几种新产品，这些产品被称为自擦底漆。这些牙本质粘接系统的所有组件都以不同的机制设计，以提高粘接强度，并建议仔细遵守所有制造商的说明。到目前为止，牙本质粘结系统中各组分对牙本质粘结的影响还不是很清楚。在这篇报道中，不同类型的牙本质粘结系统在不同的组合中被用来涂抹覆盖牙本质和抛光的釉质表面，以研究调节剂、引发剂和粘结剂对牙本质粘结的影响。结果表明，酸性调理剂是牙本质粘结系统所必需的，含有粘接剂的底漆和粘结剂可能有助于更高的粘结强度。
