概括
在内部漂白之前添加酸蚀刻可以显著提高漂白效率. 使用蚀刻 (HP + E) 的过氧化被证明是最有效的,对变色的牙显示出可靠和临床显著的结果.
科学领域:
- 牙科材料科学 牙科材料科学
- 牙周内科医院 牙周内科医院 牙周内科医院
- 审美牙科 审美牙科
背景情况:
- 内部牙变色在美学牙科中是一个挑战.
- 过氧化物基剂通常用于内部漂白.
- 优化过氧化物透是提高漂白效率的关键.
研究的目的:
- 为了比较内部漂白剂的美白效果,有和没有先前的酸蚀刻.
- 为了评估蚀刻对过氧化和胺过氧化处理的影响.
主要方法:
- 一项ex vivo研究涉及24颗被拔牙的牙,经过四个方案:35%的过氧化 (HP) 带/不带蚀刻 (E),35%的过氧化 (CP) 带/不带蚀刻.
- 漂白治疗是在21天的时间内进行的,每次更新一次.
- 每周使用光谱仪测量牙阴影,计算整体阴影变化 (∆E00) 和牙科白度指数 (WID).
主要成果:
- HP + E 组表现出最高的有效性 (∆E00 = 4.98 ± 1.09),统计学上优于 CP.
- 惠普+E表现出强烈的倾向,比惠普和CP+E更优越.
- 只有HP + E在21天后在所有样本中实现了临床显著的美白 (∆E00 > 2和∆WID > 3),这表明其可靠性很高.
结论:
- 酸蚀刻增强了内部漂白治疗的美白效果.
- 建议使用过氧化和酸蚀刻 (HP + E) 的组合来有效治疗变色的牙.
- 临床医生应该考虑在内部漂白之前加入酸蚀刻,以获得最佳的结果.

Masking and Demasking Agents
4.0K
EDTA titrations may necessitate masking and demasking agents to temporarily protect a particular metal ion in a mixture from the EDTA reaction. These agents facilitate the sequential analysis of the metal ions by forming stable complexes with some—but not all—metal ions during certain steps.
There are many masking agents, such as cyanide, fluoride, triethanolamine, thiourea, and 2,3-bis(sulfanyl)propan-1-ol (formerly 2,3-dimercapto-1-propanol), with the masking agent chosen based on...

Tooth Anatomy
2.7K
The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
