概括

与领先品牌相比,使用3%的过氧化和1.5%的酸盐的新型美白带有效地美白牙并降低牙敏感性. 这种在家进行牙美白的选择提供了美学上的好处,同时降低了过敏症的风险.

科学领域:

牙科牙科牙科牙科
整形牙科整形牙科整形牙科
牙科材料牙科材料

背景情况:

牙变色是一个常见的美学问题.
在家美白疗法很受欢迎,但可能会导致牙敏感.
新型配方旨在提高疗效并减少副作用.

研究的目的:

为了评估含有3%过氧化和1.5%酸盐的新型美白条的牙美白效果.
评估与新型美白条带相关的牙敏感性.
为了将新型条纹与对照产品 (Crest 3%过氧化条纹) 进行比较.

主要方法:

一个随机对照试验,涉及96名参与者.
实验组使用了LESENING白化条纹 (3% H2O2,1.5% KNO3);对照组使用了Crest 3D白色条纹 (3% H2O2).
在28天内,每天应用30分钟的条纹;定期测量牙颜色和敏感性,使用光谱测量和希夫评分.

主要成果:

这两组在7天内都实现了临床显著的牙美白,颜色差异 (ΔE*ab) 和白度指数 (ΔWI D) 的明显改善.
在14天后,在两组中都观察到明亮度的显著增加 (ΔL*) 和黄色的减少 (Δb*).
28天后,实验组报告没有明显的牙敏感性,而对照组经历了一些敏感性. 两组之间在美白功效方面没有发现显著差异.

结论:

LESENING美白条纹在美学上是家庭牙美白的有效方法.
与对照组相比,将酸添加到 LESENING 条纹中显著降低了牙敏感性.
这些新的美白条带提供了一个可行的选择,可以减少牙过敏,而不会影响美白结果.

Blinding

Blinding

Blinding is a commonly used method of not telling participants which treatment a subject is receiving. Blinding is a critical part of a randomized control trial or RCT. It reduces the bias that affects the results. In an RCT, blinding is used in the form of a placebo. A placebo effect occurs when untreated subjects falsely believe they have received the treatment and report improved symptoms. A placebo or a dummy treatment is administered to subjects to negate the bias caused by such an effect.

Blind Procedures

Blind Procedures

Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which...
