概括
在牙漂白前,期间或之后的化 (NaF) 应用有效地恢复了牙面膜的微硬度,而不会影响美白结果. 这种方法有助于在美容手术期间保持牙完整性.
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
- 预防性牙科 预防性牙科
背景情况:
- 牙漂白可以降低牙面膜的微硬度,可能损害牙结构.
- 重矿化剂提供了一种潜在的解决方案,以减轻漂白引起的质损伤.
- 了解再矿化剂应用的最佳时机对于有效的牙保护至关重要.
研究的目的:
- 为了评估在牙漂白之前,期间和之后应用的重矿化剂的影响.
- 评估对面膜白效果 (颜色变化) 的影响.
- 在处理后的各种深度测量质的微硬度.
主要方法:
- 104个牛切口被染色并分为八组.
- 治疗包括对照剂,单独漂白,以及在不同阶段使用3%的化 (FHA) 或2%的化 (NaF) 进行漂白.
- 在三种深度测量和统计分析了乳颜色变化 (ΔE) 和微硬度.
主要成果:
- 在漂白 (FHA+B) 过程中应用的氧化 (FHA) 显示出最小的颜色变化 (ΔE).
- 漂白显著降低了所有深度的面膜微硬度.
- 在漂白前,在漂白期间或在漂白后 (NaF/B,NaF+B,B/NaF) 应用的化 (NaF) 在很大程度上保持了质的微硬度,与对照组相比.
结论:
- 化 (NaF) 的应用有效地改善了漂白的面膜的微硬度,使其恢复到与未漂白的面膜相比的水平.
- NaF的应用不会对漂白过程的美白效果产生不利影响.
- 重矿化剂,特别是NaF,可以战略性地用于在漂白过程中和之后保护质.

04:01Factors 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:
01:23Factors Affecting Dissolution: Particle Size and Effective Surface Area
Dissolution kinetics, an essential aspect of oral drug delivery, is significantly influenced by the drug's particle size. According to the Noyes-Whitney dissolution model, the dissolution rate correlates directly with the drug's surface area. The larger the surface area, the higher the drug's solubility in water, leading to a faster drug dissolution rate. Reducing particle size increases the effective surface area, enhancing the dissolution process. Micronization and nanosizing are employed to...
