概括

低pH值的食补充剂可以改变牙树脂复合材料的颜色. 某些补充剂,如Redoxon,也可能降低特定复合材料的染色抵抗,如Filtek Z550.0.

科学领域:

牙科材料科学牙科材料科学
恢复性牙科恢复性牙科
生物材料是一种生物材料.

背景情况:

牙科修复需要颜色稳定性,以获得美观的结果.
饮食习惯,包括摄入酸性补充剂,可以影响牙科材料的寿命.

研究的目的:

评估低pH值食补充剂对三种树脂复合材料颜色稳定性的影响.
评估这些补充剂是否会影响复合材料的后续染色阻力.

主要方法:

三种树脂复合材料 (菲尔特克一批量填充,菲尔特克Z550,填充) 进行了测试.
样品被浸泡在酸性食补充剂 (Redoxon,Supradyn,Voonka原蛋白摇) 或蒸水中28天.
测量了颜色变化 (ΔE1),然后在咖啡中浸泡7天,以测量二次颜色变化 (ΔE2).

主要成果:

酸性补充剂在所有测试的复合材料中引起显著的颜色变化 (ΔE1).
在Filtek One批量填充和Filtek Z550.0中,Voonka原蛋白摇造成了最大的变色.
在Fill-Up中,Supradyn造成了最多的变色.
只有Filtek Z550-Redoxon组与对照组相比,在二次色彩变化 (ΔE2) 中显示出显著差异.

结论:

低pH值的食补充剂对树脂复合材料的色彩稳定性产生负面影响.
变色的程度取决于所使用的特定复合物和补充剂.
雷多克森泡片,然后是染色食品,在Filtek Z550修复中显著增加了变色.

Factors Affecting Solubility

Factors Affecting Solubility

Compared with pure water, the solubility of an ionic compound is less in aqueous solutions containing a common ion (one also produced by dissolution of the ionic compound). This is an example of a phenomenon known as the common ion effect, which is a consequence of the law of mass action that may be explained using Le Chȃtelier’s principle. Consider the dissolution of silver iodide:

Indicators

Certain organic substances change color in dilute solution when the hydronium ion concentration reaches a particular value. For example, phenolphthalein is a colorless substance in any aqueous solution with a hydronium ion concentration greater than 5.0 × 10−9 M (pH < 8.3). In more basic solutions where the hydronium ion concentration is less than 5.0 × 10−9 M (pH > 8.3), it is red or pink. Substances such as phenolphthalein, which can be used to determine the pH of a solution, are...

Aryldiazonium Salts to Azo Dyes: Diazo Coupling

Aryldiazonium Salts to Azo Dyes: Diazo Coupling

The reaction of weakly electrophilic aryldiazonium (also called arenediazonium) salts with highly activated aromatic compounds leads to the formation of products with an —N=N— link, called an azo linkage. This reaction, presented in Figure 1, is known as diazo coupling and occurs without the loss of the nitrogen atoms of the aryldiazonium salt. Highly activated aromatic compounds such as phenols or arylamines favor the diazo coupling reaction. The coupling generally occurs at the...
