概括
超声波振动没有显著影响单形根管堵塞中空隙形成. 然而,根部的部三分之一始终显示出更多的空洞,可能是由于圆形通道解剖学.
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
- 生物材料是一种生物材料.
背景情况:
- 在内牙闭塞中检测空隙对于评估密封效果和治疗成功至关重要.
- 微计算机断层扫描 (micro-CT) 是分析根管填充质量的宝贵工具.
- 了解不同根管三分之一的空隙形成对于改进堵塞技术至关重要.
研究的目的:
- 为了评估根管堵塞存在空洞,使用单技术与超声波振动和没有超声波振动.
- 用微型CT分析对较低单根前的空隙形成进行比较.
主要方法:
- 用单技术准备并遮盖了20个提取的下单根前.
- 第一组接受了没有振动的堵塞;第二组接受了对圆施加超声波振动的堵塞.
- 微型计算机断层扫描 (micro-CT) 用于扫描和分析堵塞的根通道,以寻找空洞.
主要成果:
- 在超声波振动和非振动组之间没有观察到空腔体积的统计学上显著差异.
- 在宫三分之一检测到空洞的比例较高,而不是根通道的中间和上角三分之一.

01:12Total Voids in Concrete
111
Total voids in concrete encompass gel water volume, capillary pores, and entrapped air. Gel water (retained within the cement hydration products) and physically entrapped or adsorbed water are significant for the hydration process. For complete hydration, it's estimated that the space needed for the products of a cubic centimeter of cement doubles. Capillary pores constitute the unoccupied space within the hydrated cement paste, with their size largely influenced by the water-to-cement...

01:18Porosity in Cement Paste

The porosity of concrete is a measure of the void spaces within its structure. These spaces impact its strength and durability significantly. When water and cement interact, a chemical reaction called hydration creates a semi-solid paste. This paste includes combined water, making up approximately 23% of the cement's dry mass, and gel water, which fills minuscule voids known as gel pores, accounting for about 28% of the cement gel volume.
