概括

口罩显著保护游泳者的牙面膜免受酸性化水造成的侵蚀. 口罩中的氨酸化物牙膏在防止质微硬性损失方面显示出最有希望的结果.

科学领域:

牙科科学牙科科学
材料科学材料科学材料科学
生物材料是一种生物材料.

背景情况:

牙侵蚀是游泳者的普遍问题,原因是暴露在酸性化水中.
牙面膜的微硬度是其结构完整性和耐侵蚀性的关键指标.

研究的目的:

在模拟的游泳环境中,评估带有和没有中和剂的口罩对牙面膜侵蚀的保护作用.
在不同口罩条件下暴露于酸性化水后,比较牙面膜的微硬度.

主要方法:

九十六个人类前被分为六组,口罩的应用不同 (没有,化牙膏,无化牙膏,CPP-ACP,化牙膏).
面膜样本经过28天的循环浸泡,模拟游泳 (酸性水2小时,人工唾液22小时).
维克斯微硬度测试,扫描电子显微镜 (SEM) 和偏光显微镜被用来评估质变化.

主要成果:

所有组都经历了质硬度的显著下降,除了使用氨酸化物牙膏口罩的组.
没有口罩的组显示了质硬度的最实质性的减少,明显超过所有口罩组.
在没有口罩的组中,SEM显示出粗的,多孔的牙表面,而口罩组保持了类似于声音牙的表面.

结论:

口罩在模拟的游泳环境中有效地减少了面膜微硬度的损失.
虽然不同类型的口罩之间没有发现显著差异,但化牙膏显示出潜在的保护作用.
建议进行进一步的临床研究,以确认这些保护措施的有效性 in vivo.

Masking and Demasking Agents

Masking and Demasking Agents

EDTA titrations may necessitate masking and demasking agents to temporarily protect a particular metal ion in a mixture from the EDTA reaction. These agents facilitate the sequential analysis of the metal ions by forming stable complexes with some—but not all—metal ions during certain steps.
There are many masking agents, such as cyanide, fluoride, triethanolamine, thiourea, and 2,3-bis(sulfanyl)propan-1-ol (formerly 2,3-dimercapto-1-propanol), with the masking agent chosen based on...

Effects of EDTA on End-Point Detection Methods

Effects of EDTA on End-Point Detection Methods

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...
