概括
这项研究比较了化剂用于牙周内涂抹层去除. 奇托桑证明有效地去除了涂抹层,牙粗度比EDTA要小,使其成为潜在的替代灌剂.
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:
- 成功的内治疗需要有效地去除涂抹层.
- 涂抹层可以阻碍愈合,并影响根管治疗的长期成功.
研究的目的:
- 为了评估根性牙微硬度修改和涂抹层去除的有效性.
- 为了比较各种合剂,包括17%的EDTA,0.2%的奇托桑,20%的N-乙半氨酸 (NAC) 和5%的Pentetic酸,用于涂抹层的去除.
主要方法:
- 使用提取的人类前牙,进行清洁和塑造,以F3大小进行.
- 标本被分为四组,用盐水 (对照组),17%的EDTA,0.2%的奇托,20%的NAC或5%的Pentetic酸治疗.
- 使用原子力显微镜评估了表面粗度.
主要成果:
- 17%的EDTA显示了最高的平均粗度平均值,其次是奇托桑,NAC和Pentetic酸.
- 涂抹层去除最有效的是17%的EDTA,其次是基托桑,NAC和Pentetic酸.
- 所有药物都从冠状和中间三分之一中去除了涂抹层,但从顶端三分之一中并没有完全去除.
结论:
- 奇托的涂抹层去除能力与EDTA相似,但表面粗度显著降低.
- 奇托桑可以被认为是内牙治疗中可行的替代最终灌剂.
- 可能需要进一步的研究来优化基托桑在顶端三分之一的疗效.

01:20Microcracking in Concrete
Microcracking in concrete refers to the tiny cracks that can form within the material even before any external load is applied. These microcracks typically occur at the interface between the coarse aggregate and the hydrated cement paste, often as a result of differential volume changes prompted by variations in stress-strain behavior, as well as thermal and moisture movement. Initially, these microcracks remain stable and do not grow substantially until the concrete is stressed to about 30...
01:24Microbial Corrosion
Microbiologically Influenced Corrosion (MIC) is a significant form of material degradation caused by the metabolic activities of microorganisms. This phenomenon poses substantial challenges across various industries, including oil and gas, maritime, and water treatment sectors.MIC occurs when microorganisms, such as bacteria, archaea, and fungi, colonize metal surfaces, forming biofilms that alter the local electrochemical environment. These biofilms can lead to the production of corrosive...
