与其他方法如EndoActivator (EA) 和Easy Clean (EC) 相比,XP-Endo Finisher (XPF) 在根通道和牙管中显示出更好的细菌减少. 虽然没有一种方法可以完全消毒道,但XPF在对抗Enterococcus faecalis.alis时表现出优越的性能.
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
- 牙科材料科学 牙科材料科学
背景情况:
- 根管道消毒对于内牙治疗的成功至关重要.
- 菌 (Enterococcus faecalis) 是持续根管感染中常见的病原体.
- 有效的灌技术对于从复杂的根管解剖学中去除细菌至关重要.
研究的目的:
- 为了比较四种不同的根管灌系统的体外细菌减少有效性.
- 为了评估EndoActivator (EA),Easy Clean (EC),被动超声波灌 (PUI) 和XP-Endo Finisher (XPF) 对Enterococcus faecalis的性能.
- 评估不同深度主要通道和牙管道中的细菌减少.
主要方法:
- 在体外研究中,使用了84个下第一个牙的仪器化牙根.
- 根植被注射了Enterococcus faecalis,并被分为四个实验组.
- 通过使用MTT测定和共聚焦激光扫描显微镜 (CLSM) 以Live/Dead BackLight技术在50,100和150微米深度量化细菌减少.
主要成果:
- 与其他方法相比,XP-Endo Finisher (XPF) 总体上显示出更好的细菌减少指数.
- 在主要通道和牙管内不同深度的XPF和Easy Clean (EC) 之间观察到显著的差异.
- 此外,XPF在更深的牙管道和牙峡中与被动超声波灌 (PUI) 相比也显示出显著的差异.
结论:
- 没有一种经过测试的灌方法可以实现根管系统的完全消毒.
- 与EndoActivator,Easy Clean和PUI相比,XP-Endo Finisher在主要通道和牙管道中表现出优越的细菌减少能力.
- 进一步的研究可能会探索灌技术的组合或修改,以提高消毒效率.

Cleaning, Sterilization, and Disinfection
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...

Methods of Sterilization I: Physical Methods
Steam sterilization uses non-toxic, low-cost moist heat in the form of saturated steam under pressure, which is fast, microbicidal, and sporicidal, and quickly warms and penetrates fabrics. Autoclaves, or steam sterilizers, expose each item to direct steam contact for a predetermined time at the necessary...
