目的：研究高氯酸铁（II）修饰的甲基丙烯酸羟乙酯（HEMA）或高氯酸铁（II）修饰的商业自蚀刻底漆（ED底漆，Kuraray Co.）对牙本质的拉伸强度的影响。方法将牛牙本质表面磨平，每个标本进行以下两种处理之一：(1)用2.0×10−6至5.0×10−4mol/g铁（II）在HEMA水溶液中浸泡，用10wt%磷酸蚀刻后；(2)用含有4.0×10−7 ~ 2.0×10−4mol/g高氯酸铁（II）的自蚀刻底漆进行底漆。然后用一种由甲基丙烯酸甲酯（MMA）、聚甲基丙烯酸甲酯（PMMA）和三正丁基硼烷（TBB）引发剂组成的粘结剂（MMA - TBB树脂）将每个样品粘接在不锈钢棒上。然后在水中浸泡1天后测定粘接牙试件的抗拉强度。结果采用方差分析和Duncan's新多元极差检验（p<0.05）进行分析。结果10wt%磷酸溶液刻蚀牙本质后，用2.0×10−4mol/g高氯酸铁（II）浸泡后，牙本质的最大平均结合强度为22.5MPa。使用1.0×10−4mol/g高氯酸铁（II）时，自蚀刻底漆的结合强度最高（19.6MPa）。这些结合使用高氯酸铁（II）修饰的HEMA底漆和MMA-TBB树脂的粘合技术，可能适用于阀座树脂粘合修复。
ObjectivesThis study was conducted to measure the tensile bond strength of a resin to dentin when the dentin was primed with iron (II) perchlorate modified aqueous 2-hydroxyethyl methacrylate (HEMA) or an iron (II) perchlorate modified commercial self-etching primer (ED primer, Kuraray Co.).MethodsBovine dentin surfaces were ground flat and each specimen underwent one of the following two treatments: (1) priming with 2.0×10−6to 5.0×10−4mol/g iron (II) perchlorate in aqueous HEMA solutions after etching with 10wt% phosphoric acid; (2) priming with self-etching primers containing 4.0×10−7to 2.0×10−4mol/g iron (II) perchlorate. Each specimen was then bonded to a stainless-steel rod with a luting agent (MMA–TBB resin) consisting of methyl methacrylate (MMA), poly(methyl methacrylate) (PMMA), and tri-n-butylborane (TBB) initiator. Tensile strengths of the bonded tooth specimens were then determined after 1day immersion in water. Results were analyzed using ANOVA and Duncan's new multiple range test (p<0.05).ResultsTensile testing revealed the maximum mean bond strengths (22.5MPa) when the dentin was primed with 2.0×10−4mol/g iron (II) perchlorate after etching with 10wt% phosphoric acid aqueous solution. The highest level of bond strength with self-etching primer (19.6MPa) was achieved using 1.0×10−4mol/g iron (II) perchlorate.SignificanceThese bonding techniques, combining the use of iron (II) perchlorate modified HEMA primers with MMA–TBB resin, are potentially applicable for seating resin-bonded restorations.
