概括

索尼克灌剂激活系统有效地减少了通道内细菌,EndoActivator和SmartLite Pro EndoActivator之间的效率相当. 虽然不能消除所有的细菌,这些系统有助于显著减少细菌负载在根运河治疗期间.

科学领域:

牙周内科医院牙周内科医院牙周内科医院
微生物学微生物学
生物材料是一种生物材料.

背景情况:

根管治疗的目的是消除内感染.
有效的消毒依赖于灌剂的输送和激活.
菌 (Enterococcus faecalis) 是持续根管感染中常见的病原体.

研究的目的:

为了比较两个声波根管灌激活系统的细菌除菌效率:EndoActivator (第一代) 和SmartLite Pro EndoActivator (第二代).
评估激活时间对消毒效率的影响.

主要方法:

使用了感染Enterococcus faecalis生物膜的人类前.
组包括注射器侧透气针 (S-N) 输送和2%的甲 (NaOCl) 的声波激活.
通过CFU计数和共聚焦显微镜来评估细菌减少.

主要成果:

与S-N输送相比,EndoActivator和SmartLite Pro EndoActivator都显著减少了内细菌 (P<0.05).与S-N输送相比,它们显著减少了内细菌 (P<0.05).
在两种声波激活装置之间没有观察到有效性的显著差异 (P>0.05).
与1分钟的声波激活相比,5分钟的NaOCl的S-N输送显示出更好的脱bridement.

结论:

使用2%NaOCl的任何声系统进行一分钟激活,在减少通道壁生物膜和通道内细菌方面表现出相似的有效性.
NaOCl的输送时间会影响消毒的有效性.
音速灌激活系统有助于减少细菌负载,尽管没有完全消除.

关键词:

菌 (Enterococcus faecalis) 是一种菌.灌剂的激活方式根管道是一种根管道.盐酸过酸盐是什么意思索尼克 (Sonic) 是一个有声波的游戏.

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.

Antimicrobial Effectiveness

Antimicrobial Effectiveness

The effectiveness of antimicrobial agents depends on various factors influencing their ability to eliminate microbial populations. Larger microbial populations require more time for complete eradication, emphasizing the importance of population size analysis when evaluating antimicrobial efficacy.Microbial resistance to antimicrobial agents varies significantly. Highly resilient microorganisms include endospores, gram-negative bacteria, and non-enveloped viruses, while prions are exceptionally...
