含有高达5%的过氧化 (HP) 的美白牙膏显示,HP的透性增加,颜色变化较10%的过氧化碳胺 (CP) 家庭漂白更小. 牙膏中较高的HP度促进了美白,但酸性pH增加了HP的透性.
科学领域:
- 牙科材料科学 牙科材料科学
- 口腔健康 口腔健康
- 整形牙科 整形牙科 整形牙科
背景情况:
- 牙美白是一种流行的美容手术.
- 过氧化 (HP) 和过氧化 (CP) 是常见的美白剂.
- 与专业治疗相比,美白牙膏的有效性和安全性需要进一步研究.
研究的目的:
- 为了比较用不同氧化 (HP) 度的美白牙膏与家用漂白治疗的效果.
- 为了评估HP的透性,颜色变化和物理化学性质.
主要方法:
- 49个前牙被分为七组,包括对照组,家庭漂白 (10% CP) 和美白牙膏 (3%,4%,5% HP).
- 测量了HP的透性,颜色变化 (ΔEab, ΔE00, ΔWID),pH,粘度和初始度.
- 统计分析包括ANOVA和后期测试.
主要成果:
- 4%的HP牙膏组表现出酸性pH,低粘度和高HP纸腔度.
- 10%的CP组在纸腔中显示出较低的HP和更大的颜色变化,除了5%的HP组在DEab和DE00外.
- 与其他组相比,使用10%CP的家庭漂白显示出优异的美白 (ΔWID).
结论:
- 使用高达5%HP的美白牙膏导致HP的透性更大,颜色变化比10%CP的家庭漂白更少.
- 牙膏中的HP度较高提高了美白效果,但酸性pH增加了HP的透性.
- 白化牙膏的效果不如家庭漂白,可能会增加牙敏感性风险.

Polyprotic Acids
Titration Calculations: Strong Acid - Strong Base
A titration is carried out for 25.00 mL of 0.100 M HCl (strong acid) with 0.100 M of a strong base NaOH. The pH at different volumes of added base solution can be calculated as follows:
(a) Titrant volume = 0 mL. The solution pH is due to the acid ionization of HCl. Because this is a strong acid, the ionization is complete and the hydronium ion molarity is 0.100 M. The pH of the solution is then:

Titration of a Polyprotic Acid
Titration Calculations: Weak Acid - Strong Base
For the titration of 25.00 mL of 0.100 M CH3CO2H with 0.100 M NaOH, the reaction can be represented as:
Mixtures of Acids
A Mixture of a Strong Acid and a Weak Acid
In a mixture of a strong acid and a weak acid, the strong acid dissociates completely and becomes a source of almost all the hydronium ions...
