概括

牙科学生通常使用安全的注射器灌力,但重复的教育显著降低了活塞力,提高了用化 (NaOCl) 治疗根运河过程中的安全性.

科学领域:

牙周内科医院牙周内科医院牙周内科医院
牙科教育牙科教育
生物医学工程生物医学工程

背景情况:

用低酸 (NaOCl) 灌注注射器对于根管治疗至关重要.
防止NaOCl挤出到周围组织,需要小心配送灌剂.
对安全的灌技术来说,量化冲压力是必不可少的.

研究的目的:

为了量化牙科本科生在NaOCl灌过程中施加的注射器活塞力.
评估教育干预对安全灌供应参数的影响.
评估重复的教育干预措施对冲压力控制的有效性.

主要方法:

一项随机控制的体外试验研究,涉及52名牙科本科生.
在3D打印牙上使用25G和30G侧通风进行注射器灌.
使用力传感器测量的冲压器力;定义了关键值 (25G的10N,30G的40N).

主要成果:

平均最大力通常低于关键值 (25G的10N以下,30G的20N以下).
超过临界力发生在25G头的数量比30G头的数量更多.
在12周的重复教育干预减少了两种类型的管的平均最大冲压力.

结论:

将力测量与教育相结合,有效地为本科生提供安全注射器灌的培训.
本科生通常不会施加过度的力度,冒着尖端挤出风险.
重复的教育干预显然可以减少冲压力,促进更安全的内牙灌.

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.
