To determine the shear bond strength and adhesive remnant index of orthodontic molar bands cemented with four different adhesives.
Eighty extracted human third molars were embedded in resin blocks and randomly assigned to one of four groups. Four different band cements were investigated: Ormco OptiBand, Dentaurum GlasTec, GC Fuji Ortho Band Paste Pak, and Unitek Multi-Cure Glass lonomer Orthodontic Band Cement. Bands were cemented on the molar crowns, and tensile loads were applied to measure the retentive strength. One-way ANOVA was performed for the retentive strength, and the Scheff multiple comparison test was applied as a post-hoc test. The Fisher exact test was used to determine significant differences in the ARI scores.
The mean tensile bond strength of GC Fuji Ortho Paste Pak was significantly higher than those of all the other groups tested. No statistically significant differences were found among the other three groups.
Among the adhesives investigated in the present study, Fuji Ortho Paste Pak resin-modified glass-ionomer cement provided the highest tensile bond strength values.
确定用四种不同黏合剂黏固正畸磨牙带的抗剪黏结强度和黏附残留指数。
将 80 颗人离体第三磨牙嵌入树脂块中,然后随机分为四组。研究了四种不同的带黏合剂:Ormco OptiBand、Dentaurum GlasTec、GC Fuji Ortho Band Paste Pak 和 Unitek Multi-Cure Glass lonomer Orthodontic Band Cement。将带黏固在磨牙冠上,然后施加拉伸载荷以测量保持力。对保持力进行单因素方差分析,并应用 Scheff 多重比较检验作为事后检验。Fisher 确切概率检验用于确定 ARI 评分的显著差异。
GC Fuji Ortho Paste Pak 的平均拉伸黏结强度明显高于其他所有测试组。其他三组之间没有统计学显著差异。
在所研究的黏合剂中,Fuji Ortho Paste Pak 树脂改性玻璃离子黏固剂提供了最高的拉伸黏结强度值。
