概括
实验用化 (SnCl2),含有或不含纳米基亚帕 (nHAP) 的实验性漆,有效地保护牙免受侵蚀性磨损. 这两种配方都显著减少了牙损失,并阻塞了牙管道.
科学领域:
- 牙科材料科学 牙科材料科学
- 生物材料工程 生物材料工程
- 口腔健康研究研究 口腔健康研究
背景情况:
- 牙侵蚀和磨损是恢复性牙科的重大挑战.
- 纳米-酸 (nHAP) 和化 (SnCl2) 以其重矿化和保护性质而闻名.
- 开发有效的漆来防止牙磨损对于保持口腔健康至关重要.
研究的目的:
- 为了评估含有纳米-酸 (nHAP) 和化 (SnCl2) 的实验性漆对牛牙的侵蚀性磨损的疗效.
- 为了比较单独的nHAP的保护作用,单独的SnCl2,以及它们在漆配方中的组合.
- 评估这些漆对牙管 obliteration 的影响.
主要方法:
- 牛牙样本经过酸的预侵蚀.
- 样品用实验性漆处理:对照剂,仅使用nHAP,仅使用SnCl2,以及组合nHAP+SnCl2.
- 侵蚀性磨损性挑战被应用了五天.
- 使用3D共聚焦激光显微镜分析了牙损失和牙管 obliteration.
主要成果:
- 含有5%SnCl2 (SnG) 的漆和20%nHAP与5%SnCl2 (nHSnG) 的组合在防止侵蚀性磨损方面比对照组和仅含nHAP的组更有效.
- 在SnG和nHSnG组之间没有观察到牙损失的显著差异.
- 与其他组相比,SNG和nHSnG两组都显示出更高程度的牙管 obliteration,它们之间没有显著差异.
结论:
- 包含5%SnCl2,有或没有20%nHAP的实验性漆是防止牙侵蚀磨损的有希望的策略.
- 在nHSnG涂料配方中,nHAP和SnCl2的组合有效地消除了牙管道,这表明有可能管理牙过敏.

01:18Effects of EDTA on End-Point Detection Methods
307
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...

01:22Effect of Sea Water on Concrete
291
Concrete exposed to seawater can undergo degradation like the dissolution of ettringite and gypsum, increasing the material's porosity and decreasing its strength. In contrast, the crystallization of salts within the concrete's pores can cause expansion, particularly above the waterline where evaporation occurs. Nonetheless, this expansion only happens when seawater, enabled by the concrete's permeability, manages to infiltrate the structure.
