- 牙科的美学 牙科的美学
- 预防性牙科 预防性牙科
背景情况:
- 牙敏感性是重要漂白的常见副作用.
- 有效的敏感性管理对于患者遵守美容牙科程序至关重要.
研究的目的:
- 为了评估含有酸和化物的持续释放脱敏凝,用于在家中进行重要漂白时降低牙敏感性.
- 评估是否消毒凝会影响漂白处理的有效性.
主要方法:
- 32名患者被随机分配到无敏化凝和安慰剂组.
- 一个16%的碳胺过氧化物漂白凝被用于在家夜警重要漂白 (NGVB) 超过三个星期.
- 患者使用数值评分尺度 (NRS) 自报敏感性;白度通过光谱测量进行测量.
主要成果:

02:07Blind 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 child was...
01:11Blinding
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.
