概括

仪器直径在牙周缩放过程中显著影响前臂肌肉活动. 与较大的仪器相比,直径较小的仪器会增加肌肉活动,这表明牙科卫生师的设计含义.

科学领域:

牙卫生工程学牙卫生工程学
对仪器设计的生物机械分析.

背景情况:

牙科仪器手柄的设计对于用户的舒适性和预防肌肉骨疾病至关重要.
之前的研究已经探讨了各种因素,但质量和直径对肌肉活动的具体影响需要进一步澄清.

研究的目的:

为了比较仪器柄质量和直径在模拟牙周缩放过程中对前臂肌肉活动的影响.
为了评估10个商业可用的仪器设计.

主要方法:

25名牙科卫生师参与了一项IRB批准的研究.
仪器按质量和直径 (大/小,轻/重) 分类.
表面电肌图 (sEMG) 用随机仪器在模拟缩放过程中测量肌肉活动.

主要成果:

仪器直径显著增加了 flexor pollicis longus的肌肉活动 (p=0.001).
更小的直径仪器导致延伸指的肌肉活动增加,延伸指的通用和延伸的放射性短腿 (p=0.08).
仪器质量在任何测试的肌肉群中都没有显著影响肌肉活动.

结论:

仪器直径在缩放期间影响前臂肌肉活动的因素比质量更为重要.
直径较小的仪器可能会导致更大的肌肉炼,可能会影响长期的人体健康.
建议在临床环境中进行进一步的研究,以评估实际影响.

Hand hygiene

Hand hygiene

Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Handwashing I: Introduction and Types of Equipment

Handwashing I: Introduction and Types of Equipment

Handwashing is hand hygiene with plain or antimicrobial soap and water to physically remove dirt, organic material, and microorganisms. However, it may not kill all microorganisms. The handwashing procedure requires a hand wash basin, liquid soap, paper towels, a domestic waste bin, and disposable nail cleaner as optional equipment.
Hand wash basins in clinical areas should have faucets that can be turned on and off without using the hands; that is, they should be non-touch or lever-operated....
