摘要

(1) 背景:使用牙科刮治器进行牙周器械治疗与不适、疲劳和肌肉骨骼疾病有关。本研究的目的是比较三种不同刮治器的舒适度、疲劳度和肌肉工作情况。(2)方法:八名卫生学家每人使用三种不同的刮治器刮治三颗类型牙。A 型刮刀是一种具有新颖自适应设计的原型,B 型刮刀采用传统的不锈钢设计,C 型刮刀采用传统的硅胶包覆手柄。研究人员记录了四块肌肉的工作时间、舒适度、疲劳度、触觉反馈、握把和刀片位置以及夹持和抓握力度。统计分析采用一般线性模型(GLIM)和 Tukey 后检验法进行。显著性水平设定为 p < 0.05。(3) 结果:使用 Curette A 时,舒适度、正确抓握、指尖位置和刀片与牙齿的适应性明显更好(p < 0.05)。与 B 和 C 相比,A 型刮匙所需的总肌肉工作量和单个肌肉工作量均显著减少,因此使用 A 型刮匙后的疲劳程度显著降低,但触觉反馈水平却与 B 和 C 相似(p < 0.05)。(4) 结论:自适应牙周刮治器原型的人体工学性能明显优于两种采用刚性手柄设计的传统器械。

Evaluating the Ergonomic Performance of a Novel Periodontal Curette with Adaptive Handle Design
(1) Background: Periodontal instrumentation with dental curettes is associated with discomfort, fatigue, and musculoskeletal diseases. The goal of this study was to compare comfort, fatigue, and muscle work using three different curettes. (2) Methods: Eight hygienists each scaled three typodonts using the three different curettes. Curette A was a prototype with a novel adaptive design, Curette B had a conventional stainless-steel design, and Curette C featured a conventional silicon-covered handle. Time-based work in four muscles, comfort, fatigue, tactile feedback, grip and blade position, and pinch and grasp strength were recorded. Statistical analysis was performed using a General Linear Model (GLIM) and Tukey’s post hoc test. The level of significance was set at p < 0.05. (3) Results: Comfort, correct grasp, fingertip placement, and blade-to-tooth adaptation were significantly better with Curette A (p < 0.05). While pinch and grasp strength were significantly reduced post-instrumentation for Curettes B and C (p < 0.05), they remained unchanged for Curette A. Curette A required significantly less total muscle work and work in individual muscles, resulting in significantly less post-instrumentation fatigue than for Curettes B and C, but similar levels of tactile feedback (p < 0.05). (4) Conclusions: The ergonomic performance of a prototype adaptive periodontal curette was significantly better than that of two conventional instruments with rigid handle designs.
