The composition of universal adhesives is highly diverse. The purpose of this in vitro study was to compare the shear bond strength of a composite with five different universal adhesives to human enamel and dentin.
The shear bond strength of a composite (G-aenial Universal Injectable) to human enamel and dentin was tested in selective enamel etching mode before and after thermocyclic aging (10,000 cycles) using five different universal adhesive systems (Adhese Universal VivaPen, Clearfil Universal Bond Quick, G-Premio Bond, Prime&Bond active, and Scotchbond Universal Plus). Two-bottle systems (OptiBond FL and G2-Bond Universal) were used as control. Scanning electron microscopy was conducted of the bonding interface.
Significant differences in shear bond strength values were found among the five evaluated universal adhesives. Lowest shear bond strength values were observed for 2-hydroxyethylmethacrylate (HEMA)-free systems. Thermocyclic aging did not significantly reduce shear bond strength values indicating that the initial bond remains stable.
The clinical use of universal adhesives Adhese Universal VivaPen, Clearfil Universal Bond Quick, and Scotchbond Universal Plus can be encouraged as they provided comparable or even better shear bond strength values than the two-bottle controls.
Universal adhesives that were developed for the same indication and approved for clinical use demonstrated variety in shear bond strength values. When applied in the selective enamel etching mode, a stable bond can be expected from adhesives containing HEMA and monomers with phosphate groups.
通用粘结剂的组成高度多样化。本体外研究的目的是比较 5 种不同通用粘结剂与牙釉质和牙本质的复合剪切粘结强度。
在选择性釉质酸蚀模式下，使用 5 种不同的通用粘结剂系统（Adhese Universal VivaPen、Clearfil Universal Bond Quick、G-Premio Bond、Prime&Bond active 和 Scotchbond Universal Plus），对人牙釉质和牙本质进行复合剪切粘结强度测试，然后进行热循环老化（10000 次循环）。OptiBond FL 和 G2-Bond Universal 作为对照组使用双瓶系统。对粘结界面进行扫描电子显微镜观察。
在评估的 5 种通用粘结剂中，剪切粘结强度值存在显著差异。不含 2-羟乙基甲基丙烯酸酯（HEMA）的体系观察到最低的剪切粘结强度值。热循环老化并未显著降低剪切粘结强度值，表明初始粘结保持稳定。
可以鼓励使用通用粘结剂 Adhese Universal VivaPen、Clearfil Universal Bond Quick 和 Scotchbond Universal Plus，因为它们提供的剪切粘结强度值与双瓶对照组相当，甚至更好。
为相同适应证开发并经临床批准使用的通用粘结剂在剪切粘结强度值方面存在差异。当以选择性釉质酸蚀模式应用时，含有 HEMA 和具有磷酸盐基团的单体的粘结剂可以预期具有稳定的粘结。
