概括

与35%的过氧化 (HP) 或单独的HP相结合的紫色LED (VLED) 显示出优异的牙美白,但与单独的VLED相比,牙敏感性增加. 单独使用VLED对漂白的效果不那么好.

科学领域:

牙科材料科学牙科材料科学
在牙科中使用光化学.
审美牙科审美牙科

背景情况:

牙变色是一个常见的美学问题.
过氧化 (HP) 和光激活广泛用于牙漂白.
紫色LED (VLED) 为光激活漂白提供了一种新的方法.

研究的目的:

为了评估紫色LED (VLED) 的漂白效率和牙敏感性 (TS),使用或不使用35%的过氧化 (HP).
为了比较仅HP,仅VLED和HP+VLED治疗的结果.

主要方法:

一个单盲随机对照试验,涉及84名参与者.
三个治疗组:35%的HP,VLED和HP+VLED,每隔7天进行3次治疗.
使用色度测量 (ΔEab, ΔE00, ΔSGU, ΔWID) 和视觉模拟尺度 (VAS) 来测量牙敏感度.

主要成果:

与单独使用VLED相比,HP和HP + VLED组显示出明显更高的漂白效率.
惠普+VLED和惠普组报告了明显更高的牙敏感性风险和强度.
单独使用VLED的漂白疗效低于HP和HP+VLED在治疗后的7天和30天.

结论:

35%HP,有或没有VLED,提供优质的牙美白,但与牙敏感性增加有关.
单独的VLED显示了较低的漂白效率,并且与较低的牙敏感性有关.
将35%的HP与VLED相结合,不会提高单独HP的漂白效率,但会增加牙的敏感性.

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.
