概括

声波和超声波激活显著提高了根管治疗的最终灌效率,特别是在顶部三分之一. 虽然所有激活方法都减少了碎片,但Eddy和Irrisafe显示出比内激活更好的涂抹层去除.

科学领域:

牙周内科医院牙周内科医院牙周内科医院
牙科材料科学牙科材料科学
生物医学工程生物医学工程

背景情况:

灌对于根管治疗至关重要,可以到达机械清洁无法进入的区域.
有效的碎片和涂抹层的去除对于成功的内牙结局至关重要.

研究的目的:

为了比较声波和超声波灌激活系统与传统针式灌的有效性.
为了评估直圆形根通道的冠状,中间和顶端三分之一的碎片和涂抹层的去除.

主要方法:

准备了60个带有直径圆形通道的人类下切口,并分为四组.
协议包括Eddy声波激活,使用Endosonic和Irrisafe设备的被动超声波灌 (PUI),以及手动注射器灌 (控制).
扫描电子显微镜 (SEM) 用于评估碎片和涂抹层的去除.

主要成果:

没有任何协议可以完全消除碎片和涂抹层.
与手动灌相比,这三个激活系统都显著减少了顶峰碎片.
艾迪和Irrisafe激活显示在顶端三分之一显著的涂抹层减少;内分泌激活没有达到显著的意义.

结论:

声波和超声波激活可提高最终灌效率,以清除根通道中的碎片和涂抹层.
与Eddy和Irrisafe系统相比,内激活在涂抹层去除方面效率较低.

Preparation of Samples for Electron Microscopy

Preparation of Samples for Electron Microscopy

To be visualized by an electron microscope, either transmission or scanning, biological samples need to be fixed (stabilized) so the electron beam does not destroy them and dried thoroughly (desiccated/dehydrated) so the vacuum does not affect them. Fixation needs to be done as quickly as possible because the sample properties will start changing as soon as it is removed from its natural environment. For example, in a tissue sample, the oxygen levels begin decreasing, causing an altered...
