To evaluate the shear bond strength (SBS) of a microfilled resin restorative material and an amalgam alloy to dentin using the Amalgambond Plus adhesive system with a variety of bonding regimens.
The study design incorporated bonding composite to both dry and moist dentin using open-ended plastic matrices and closed-ended gelatin capsules. In addition, the bond strength of amalgam to dry dentin was determined.
The mean SBS of Silux Plus to dentin using Amalgambond without the HPA powder ranged from 17.55 +/- 1.96 MPa to 22.47 +/- 3.89 MPa. The SBS range observed when the microfilled composite was bonded to dentin with Amalgambond Plus (includes the HPA powder) was from 20.33 +/- 3.84 MPa to 22.50 +/- 3.69 MPa. There was no significant difference (P > 0.05) in the SBS of the microfilled resin restorative material to dentin between the groups that were bonded using an open-ended cylinder-shaped plastic matrix and those prepared using a closed-ended gelatin capsule matrix, nor was there a difference (P > 0.05) in the SBS when the microfilled resin restorative material was bonded to either wet or dry dentin surfaces. The use of multiple applications of Amalgambond adhesive did not markedly increase the SBS with this system. The mean bond strength of amalgam alloy (Dispersalloy) to dentin using Amalgambond Plus was 10.41 +/- 1.47 MPa.
使用多种粘结方案的Amalgambond Plus粘结系统,评估一种微填料树脂修复材料和一种汞合金与牙本质的剪切粘结强度(SBS)。
本研究设计采用开放式塑料基质和封闭式明胶胶囊,将复合树脂粘结至干燥和潮湿的牙本质。此外,还测定了汞合金与干燥牙本质的粘结强度。
不使用HPA粉末的情况下,使用Amalgambond时Silux Plus与牙本质的平均SBS为17.55±1.96MPa至22.47±3.89MPa。当使用Amalgambond Plus(包括HPA粉末)将微填料复合树脂粘结至牙本质时,观察到的SBS范围为20.33±3.84MPa至22.50±3.69MPa。在使用开放式圆柱形塑料基质粘结的组与使用封闭式明胶胶囊基质制备的组之间,微填料树脂修复材料与牙本质的SBS无显著差异(P>0.05),当微填料树脂修复材料粘结至湿或干牙本质表面时,SBS也无差异(P>0.05)。多次应用Amalgambond粘结剂并不能显著提高该系统的SBS。使用Amalgambond Plus时,汞合金(Dispersalloy)与牙本质的平均粘结强度为10.41±1.47MPa。
