Abstract

A restorative resin was bonded to EDTA-treated dentin by means of a mixture of glutaraldehyde and HEMA. The bond exhibited a tensile strength of 17.5 +/- 1.0 MPa (mean +/- SEM) and was unaffected by water storage at 37 degrees C for up to 6 months. The glutaraldehyde/HEMA mixture was found to be most effective when the pH was between 2 and 5; an application time of 10 s was found to be sufficient for the glutaraldehyde/HEMA mixture as well as for the EDTA-solution.

摘要

一种修复性树脂通过戊二醛和甲基丙烯酸羟乙酯（HEMA）的混合物粘结到经乙二胺四乙酸（EDTA）处理的牙本质上。该粘结剂的拉伸强度为17.5±1.0兆帕（平均值±标准误），并且在37摄氏度下储存长达6个月的水浸条件下不受影响。发现当pH值在2至5之间时，戊二醛/HEMA混合物最为有效；发现10秒的涂抹时间对于戊二醛/HEMA混合物以及EDTA溶液而言都是足够的。
