概括
用含银的溶液预处理牙,会对通用粘合剂的粘合产生负面影响. 虽然这两种溶液都降低了结合强度,但以氨为基础的Riva Star通过激活较少的矩阵金属蛋白酶 (MMP) 来显示出更好的长期稳定性.
科学领域:
- 牙科材料科学 牙科材料科学
- 粘合式牙科 粘合式牙科
- 生物材料是一种生物材料.
背景情况:
- 万能粘合剂在恢复性牙科中被广泛使用.
- 含有银的溶液正在探索潜在的抗菌益处.
- 这些溶液对粘合剂对牙粘合耐久性的影响尚未完全理解.
研究的目的:
- 评估氨基基和水基银溶液对牙的通用粘合剂粘合的影响.
- 评估这些预处理对矩阵金属蛋白酶 (MMP) 活性的影响.
- 为了确定1年人工老化后的粘合性能和MMPs活动.
主要方法:
- 60个人的牙被分为六组,根据牙预处理 (Riva Star,Riva Star Aqua或没有) 和通用粘合剂 (Zipbond Universal) 蚀刻模式 (自蚀或蚀刻和冲洗).
- 微拉力键强度 (μTBS) 在基线和12个月人工衰老后进行了测试.
- 在现场采用淋巴镜来分析MMPs的活动;SEM和EDS也进行了.
主要成果:
- 丁丁的预处理和老化显著降低了μTBS,不管是如何蚀刻.
- 两种含银溶液之间没有发现μTBS的显著差异.
- 里瓦星水和蚀刻显著增加了MMP的活性,独立于储存时间.
结论:

01:26EDTA: Auxiliary Complexing Reagents
589
EDTA titrations are usually carried out in highly basic conditions, where the fully deprotonated form of EDTA, Y4−, actively complexes with the free metal ions in the solution. Several metal ions precipitate as hydrous oxide (hydroxides, oxides, or oxyhydroxides) under these conditions, lowering the concentration of free metal ions in the solution. For this reason, auxiliary complexing agents or ligands such as ammonia, tartrate, citrate, or triethanolamine are used in EDTA titrations to...

Different methods, such as visual observance of metal-ion indicators, spectroscopic techniques, and potentiometric methods, can determine the endpoint of an EDTA titration.
In the visual method, metal-ion indicators (metallochromic dyes), which have distinct colors in their free and complex forms, are added to the mixture to signal the titration's end point. They form stable complexes with metal ions, but these complexes are weaker than the corresponding metal–EDTA complexes. As a...
