摘要

本研究评估了两种叶绿素衍生物--叶绿素铜钠(Cu-Chl)和叶绿素铁钠(Fe-Chl)--对自固化粘接剂(4-META/MMA-TBB树脂)和牙本质之间粘接强度的影响。我们制备了五种水性底漆,分别含有 35% 的 2- 羟乙基甲基丙烯酸酯和 0.007% 的 Cu-Chl、0.07% 的 Cu-Chl、0.007% 的 Fe-Chl、0.07% 的 Fe-Chl,或者既没有 Cu-Chl,也没有 Fe-Chl(无 Chl)。用 10%磷酸(10PA)对拔出的人类牙本质表面进行蚀刻、打底,然后用 4-META/MMA-TBB 树脂将其粘结到树脂块上。常规蚀刻剂(10-3)和不含底剂的 10PA 作为对照。计算 20 个试样的算术中值,并使用非参数的 Steel-Dwass 检验(α = 0.05)进行统计分析。0.007% Cu-Chl 组的粘结强度最大,其次是 0.07% Cu-Chl、0.07% Fe-Chl、10-3、0.007% Fe-Chl、无 Chl 和 PA/无引物组。在 0.007% Fe-Chl、0.07% Fe-Chl 和 10-3 之间没有观察到明显的差异。用 10PA 蚀刻的牙本质的粘接强度受叶绿素衍生物的类型和浓度的影响。在将 4-META/MMA-TBB 树脂与牙本质粘合时,Cu-Chl 而不是 Fe-Chl 应作为表面处理剂的一种成分。

Effects of sodium copper- and sodium iron-chlorophyllin primers on resin bonding to dentin

This study evaluated the effects of two chlorophyll derivatives, sodium copper chlorophyllin (Cu-Chl) and sodium iron chlorophyllin (Fe-Chl), on the bond strength between a self-curing luting agent (4-META/MMA-TBB resin) and dentin. Five aqueous primers containing 35% 2-hydroxyethylmethacrylate with 0.007% Cu-Chl, 0.07% Cu-Chl, 0.007% Fe-Chl, 0.07% Fe-Chl, or neither Cu-Chl nor Fe-Chl (no-Chl) were prepared. The extracted human dentin surfaces were etched with 10% phosphoric acid (10PA), primed, and bonded to a resin block using the 4-META/MMA-TBB resin. A conventional etching agent (10-3) and 10PA without primer (PA/no-primer) were used as controls. The microtensile bond strength was determined after 48 h. The arithmetic medians for 20 stick specimens were calculated and statistically analyzed using a nonparametric Steel-Dwass test (α = 0.05). The maximum bond strength was achieved in the 0.007% Cu-Chl group, followed by those in the 0.07% Cu-Chl, 0.07% Fe-Chl, 10-3, 0.007% Fe-Chl, no-Chl, and PA/no-primer groups. No significant difference was observed between 0.007% Fe-Chl, 0.07% Fe-Chl, and 10-3. The bond strength to dentin etched with 10PA was influenced by the type and concentration of the chlorophyll derivatives applied. Cu-Chl rather than Fe-Chl should be useful as a component of surface treatment agents for bonding 4-META/MMA-TBB resin to dentin.

期刊介绍: The European Journal of Oral Sciences is an international journal which publishes original research papers within clinical dentistry, on all basic science aspects of structure, chemistry, developmental biology, physiology and pathology of relevant tissues, as well as on microbiology, biomaterials and the behavioural sciences as they relate to dentistry. In general, analytical studies are preferred to descriptive ones. Reviews, Short Communications and Letters to the Editor will also be considered for publication. The journal is published bimonthly.
