概括
涂抹OFF和17%的乙烯基胺三酸 (EDTA) 有效地去除了根运河涂抹层. 这两种灌剂,当与被动超声波灌一起使用时,在清理通道壁上表现出相似的有效性.
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
背景情况:
- 根管仪器产生了涂抹层,可能会阻碍内牙治疗的成功.
- SmearOFF是一种内牙灌剂,旨在同时去除涂抹层和细菌.
研究的目的:
- 为了比较SmearOFF和17%乙二胺三酸 (EDTA) 在从根管中去除涂抹层的有效性.
- 为了评估根通道的冠状,中间和顶端三分之一的涂抹层去除.
主要方法:
- 64个单通道下前被分为两个组:6%的低 (NaOCl) /SmearOFF和6%的NaOCl/17%的EDTA.
- 用ProtaperNext系统塑造了根管,并用6%的NaOCl灌,然后用SmearOFF或17%的EDTA,以及被动的超声波灌激活.
- 使用扫描电子显微镜评估了涂抹层的去除.
主要成果:
- 虽然17%的EDTA在所有根管三分之一中显示出数值较低的平均涂抹层得分,但SmearOFF和17%的EDTA组之间没有统计学上显著的差异.
- 这两种灌方案都证明了冠状,中部和顶部区域的有效涂抹层去除.
结论:
- 17%的EDTA和SmearOFF都起到有效的合剂作用,用于根管中去除涂抹层.
- 被动超声波灌可以提高SmearOFF和17%的EDTA在清除根管壁上的有效性.

5.4K
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...

4.2K
A scanning electron microscope (SEM) is used to study the surface features of a sample by using an electron beam that scans the sample surface in a two-dimensional manner. Typically, areas between ~1 centimeter to 5 micrometers in width can be imaged. SEM can be used to image bacteria, viruses, tissues as well as larger samples like insects. Conventional SEM gives a magnification ranging from 20X to 30,000X and spatial resolution of 50 to 100 nanometers.
