概括
互换文件25/0.08导致更多的细菌挤出比较大的40/0.06文件,特别是被动超声波灌 (PUI). 根管制备中较大的文件大小减少了尖端细菌挤出.
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
背景情况:
- 角细菌挤出是根运河制备中的一个问题.
- 互换文件被广泛使用,但它们对挤出的影响需要评估.
研究的目的:
- 用Reciproc文件25/0.08和40/0.06与不同的灌技术进行比较.
主要方法:
- 七十个被Enterococcus faecalis污染的人类前被用Reciproc 25/0.08或40/0.06.仪器仪表.
- 灌方法包括传统的注射器灌和被动的超声波灌 (PUI) 以一个或两个激活周期.
- 挤出碎片被收集,培养,并以殖民地形成单位 (CFU/mL) 量化.
主要成果:
- 与Reciproc 40/0.06 (P<0.05) 相比,使用Reciproc 25/0.08的仪器导致细菌挤出显著更高 (P<0.05).
- 被动超声波灌 (PUI) 当与较小的 Reciproc 25/0.08 文件一起使用时,进一步增加了细菌挤出.
结论:
- 所有测试的仪器仪表技术都导致了角细菌挤出.
- 使用较大的文件大小,如Reciproc 40/0.06,与减少的尖端细菌挤出有关.

Factors Affecting the Risk of Infection
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...

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...
Key Techniques in Microbiology
Aseptic techniques prevent contamination, ensure experimental accuracy, and protect researchers and microbial cultures. These techniques are essential in clinical, industrial, and research settings where sterility is required.Maintaining Sterility in Laboratory PracticesScientists maintain sterility by sterilizing tools with heat or chemicals, disinfecting work surfaces, and handling cultures in controlled environments. Working near an open flame or within a laminar flow hood reduces the risk...
