概括
紫色LED光与碳胺过氧化物相结合,在实验室环境中显著增强了牙美白效果. 然而,光源显著增加了内温度,但没有影响面表面的粗度.
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.
- 摄影化学的使用.
背景情况:
- 牙漂白是一种常见的美容牙科手术.
- 高度漂白剂是有效的,但可能会引起副作用.
- 光激活用于提高漂白效率.
研究的目的:
- 评估紫色LED光线对牙颜色变化,牙内膜温度和牙面粗度的影响.
- 为了将漂白结果与高度过氧化 (HP) 和碳胺过氧化 (CP) 进行比较,具有或没有LED激活.
- 为了评估紫色LED光的独立效应.
主要方法:
- 牛切口冠状经历了各种美白方案:对照组,35%HP,37%CP,LED/HP,LED/CP,以及单独使用LED.
- 测量了颜色变化 (ΔE00),白度指数 (ΔWID),温度变化 (Δ°C) 和表面粗度 (Ra).
- 用统计模型分析数据,包括通用线性模型和非参数测试.
主要成果:
- 带有或没有LED的HP和CP,与单独使用LED相比,导致更大的颜色变化.
- LED和CP (LED/CP) 的组合显示了比单独CP更高的颜色变化.

01:14Changes in Skin Color: Clinical Perspectives
3.3K
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.

8.7K
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...
