概括

儿童用铁补充剂增加了牙修复材料的表面粗度. 玻璃离子体水泥 (GIC) 显示出最多的降解,而树脂基材料更耐铁暴露.

科学领域:

材料科学材料科学材料科学
儿科牙科儿科牙科
生物材料是一种生物材料.

背景情况:

儿童补充铁是常见的.
儿科牙科的修复材料可能会接触到铁补充剂.
牙科材料的表面特性可能会影响其寿命和性能.

研究的目的:

评估两种儿科铁补充剂配方对常见牙修复材料表面粗度的影响.
为了比较对铁补充剂暴露的物质特异反应.

主要方法:

在体外研究使用四种修复材料:复合树脂,复合物,可流复合物和玻璃离子体水泥 (GIC).
标本每天在Ferrum®或Ferro Sanol® B中浸泡28天.
表面粗度 (Ra) 在基线,第1天,第7天和第28天使用接触型仪测量.

主要成果:

所有材料的表面粗度随着时间的推移而增加 (p < 0.001).
在所有条件下,玻璃离子体水泥 (GIC) 在第28天表现出最高的表面粗度.
与对照组相比,基于树脂的材料显示出明显的粗度增加,但比GIC更耐药.

结论:

儿童对铁补充剂的暴露会导致牙修复材料的材料特异性表面降解.
玻璃离子体水泥 (GIC) 非常容易受到铁补充剂表面粗的影响.
基于树脂的材料提供了更大的阻力,这表明小心选择的材料对儿童在铁疗法是至关重要的.

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 result, EDTA...
