概括
计算机断层扫描 (CT) 扫描用于二级和三级患者的整形手术规划,在中心关系 (CR) 和最大间位置 (MI) 之间没有显著的状体定位差异. 闭塞装置在CT检查中不是强制性的.
科学领域:
- 牙科 牙科是指牙科的专业.
- 矯正牙科 矯正牙科是一種矯正牙科.
- 口腔和牙面部外科手术
背景情况:
- 准确的状骨的定位对于正手术中的虚拟手术规划至关重要.
- 骨类II和III的缺陷往往需要进行正手术.
- 在此背景下,对计算机断层扫描 (CT) 扫描的闭塞装置的必要性进行了辩论.
研究的目的:
- 在虚拟手术规划期间,检查骨II和III类患者的CT扫描中状体的位置.
- 为了确定闭塞器件是否是必须的,在做直肠外科手术前进行CT检查.
主要方法:
- 对42个CT扫描的回顾性分析,这些扫描来自25-40岁的患者,这些患者正在接受正手术.
- CT扫描被评估为中心关系 (CR) 和最大间位置 (MI).
- 进行了统计分析,以评估观察者间和观察者内部的可靠性和位置差异.
主要成果:
- 在CR和MI之间的状体定位上没有发现统计学上显著的差异.
- 观察者间和观察者内部的可靠性对两个位置都是一致的.
- 通过特定的评分方法来缓解性别偏见.
结论:
- 实现CR或MI的下操纵不会在CT扫描中产生对囊定位的统计学上显著差异.
- 使用定位指南用于虚拟预先规划CT扫描并非必不可少.

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.
