概括

紫光照射提高了碳胺过氧化物 (CP) 在办公室牙漂白的有效性,而不会增加牙的敏感性. 这一发现表明牙科美学有前途的进步,尽管建议进行进一步的研究.

科学领域:

牙科科学牙科科学
生物材料科学生物材料科学
摄影化学的使用.

背景情况:

办公室内牙漂白是一种常见的美容牙科手术.
碳胺过氧化物 (CP) 是一种广泛使用的漂白剂.
探索提高漂白效率和患者舒适度的方法至关重要.

研究的目的:

系统地审查和分析紫光照射对碳胺过氧化物 (CP) 在办公室牙漂白的疗效.
为了确定紫光照射是否会增加牙漂白的敏感性.
评估紫光对CP漂白结果的整体影响.

主要方法:

遵循PRISMA协议;使用RoB 2工具评估偏差风险;使用GRADE分析证据确定性.

主要成果:

在分析中包括了三个RCT.
在紫光照射CP (MD, 3.35; 95% CI, 0.80, 5.89) 观察到牙颜色变化 (CC) 的统计学显著改善.
两组之间没有发现漂白灵敏度 (BS) 的显著差异 (RD,0.09;95% CI, -0.03,0.21).

结论:

紫光照射在办公室手术过程中显著增强了碳胺过氧化物 (CP) 的牙漂白效果.
添加紫光似乎不会增加手术后的牙敏感性.
虽然有希望,但这些发现是基于中等确定性的证据,需要谨慎解释.

Ultraviolet and Visible (UV–Vis) Spectroscopy: Overview

Ultraviolet and Visible (UV–Vis) Spectroscopy: Overview

Ultraviolet–visible (UV–visible or UV–Vis) spectroscopy is an analytical technique that investigates the interaction between matter and UV–Vis light within the electromagnetic spectrum. This method is widely used for its versatility, simplicity, and relatively quick data acquisition, making it valuable for both qualitative and quantitative analysis. When UV–Vis radiation passes through a material, molecules absorb light depending on the energy required for...

UV–Vis Spectroscopy of Conjugated Systems

Organic compounds with conjugated double bonds show strong absorption features in the UV–visible region of the electromagnetic spectrum attributed to π → π* electronic excitations. Generally, a UV–vis absorption spectrum is recorded as a plot of absorbance vs wavelength. The wavelength of maximum absorbance, which manifests as a peak in the absorption spectrum, is denoted as λmax.
One of the factors influencing λmax is the extent...
