概括
用10%的碳化物过氧化物 (CP) 凝42分钟积极刷牙,可以实现过氧化 (HP) 透和牙美白,与四周的被动应用相比. 这种方法为家庭漂白提供了更快的替代方案.
科学领域:
- 牙科材料科学 牙科材料科学
- 生物材料是一种生物材料.
- 整形牙科 整形牙科 整形牙科
背景情况:
- 在家漂白是一种常见的美容牙科手术.
- 传统的方法包括长时间被动应用漂白凝.
- 优化应用方法可以提高效率和患者合规性.
研究的目的:
- 通过刷牙与被动应用来比较主动在家漂白凝应用的有效性.
- 为了评估过氧化 (HP) 透到牙组织.
- 通过不同的应用方法来评估牙颜色变化的程度.
主要方法:
- 三十五个前被分为五组,包括对照组,10%的碳酸过氧化物 (CP) 的被动应用和10%的CP (1,28或120次) 的活跃刷毛.
- 积极刷牙是使用软毛牙刷进行的,每次刷牙90秒.
- 使用UV-VIS光谱测量过氧化的透度,使用光谱仪量化颜色变化.
主要成果:
- 有120次活跃刷毛应用的组显示HP透率最高.
- 无论是被动应用 (28次) 还是28次主动刷刷应用,都产生了类似的中间HP透水平.
- 在被动应用 (28次),28次活跃刷牙和120次活跃刷牙组中观察到显著的牙颜色变化 (ΔE),超过了单次刷牙应用组.
结论:
- 积极应用10%的CP凝通过刷毛总共42分钟可以实现HP透和漂白效率,与被动四周疗法相提并论.
- 这种主动刷牙方法提供了一个潜在的更快,同样有效的替代在家用牙美白.
- 需要进一步的临床研究来证实这些研究结果在体内.

01:14Changes in Skin Color: Clinical Perspectives
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

01:15Oxidations of Aldehydes and Ketones to Carboxylic Acids
Oxidation of aldehydes and ketones results in the formation of carboxylic acids. Aldehydes, bearing hydrogen next to the carbonyl group, are easily oxidized compared to ketones. This is because an aldehydic proton can easily be abstracted during oxidation.
Aldehydes readily undergo oxidation in strong oxidizing agents such as potassium permanganate and chromic acid. The oxidation can also be carried out using mild oxidizing agents such as silver oxide. In fact, aldehydes can be easily oxidized...
