概括
这项研究发现,将含的甲酸盐 (Sr-FAp) 添加到30%的过氧化 (HP) 中,可以有效地使牙变白,同时保护牙. 该Sr-FAp添加剂有助于保持微硬度和结构,尽量减少漂白过程中的损坏.
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
- 保守的牙科 保守的牙科
背景情况:
- 用过氧化 (HP) 进行牙漂白可以改变牙面的质地.
- 在重要的牙漂白过程中最大限度地减少阴性损伤是临床上的挑战.
- 含的甲酸 (Sr-FAp) 纳米颗粒正在研究潜在的保护作用.
研究的目的:
- 为了评估30%的HP与不同度的Sr-FAp结合的美白效果.
- 评估Sr-FAp修饰的HP对质表面性能的影响,包括光泽度,粗度和微硬度.
- 为了确定Sr-FAp是否可以减轻由过氧化漂白引起的牙损伤.
主要方法:
- 牛牙样本被染色并分为五组:蒸水,30%的HP和30%的HP含1,5或10重%的Sr-FAp.
- 漂白疗法被应用三次,每次20分钟.
- 评估包括颜色变化 (ΔEab, ΔWI D, ΔE00),光泽度,表面粗度,微硬度以及处理前后的微结构分析.
主要成果:
- 与对照组相比,所有HP组都实现了显著的美白 (p <0.05),基于Sr-FAp度没有显著差异.
- 在所有HP组中,光泽度都下降了,10重%的Sr-FAp组显示出最显著的减少 (p <0.05).
- 表面粗度保持不变,而微硬度在10%重量%的Sr-FAp组中最高 (p <0.05),表明具有保护作用.
结论:
- 将Sr-FAp纳入30%的HP可以提供有效的牙美白,同时保持牙面膜的微硬度和微结构.
- 保护性Sr-FAp层似乎形成在质表面上,减轻了漂白引起的损伤.
- 在牙美白配方中,Sr-FAp显示出作为重矿化填充剂的潜力,以提高安全性和有效性.

The minerals contained in all of the food we consume are essential for our organ systems. However, certain essential minerals, such as calcium, phosphorus, magnesium, manganese, and fluoride, largely affect bone health.
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...

36.6K
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:
