概括
不同的牙刷会对牙材料产生不同的影响. 一些牙刷会对树脂复合材料和牙产生更大的磨损,这凸显了为最佳口腔健康和牙修复寿命而选择适当的刷牙工具的必要性.
科学领域:
- 牙科生物材料科学 牙科生物材料科学
- 口腔卫生研究的研究.
- 牙科中的三元学.
背景情况:
- 通过牙刷机械地去除生物膜对于预防虫和牙周病至关重要.
- 为有效和安全的清洁提供最佳牙刷参数仍然未定义.
- 这项研究调查了牙刷刷毛的扩散和牙基板上的磨损潜力.
研究的目的:
- 为了评估七种不同的牙刷在质和树脂复合材料上的磨损潜力.
- 为了评估经过模拟随时间推移的刷毛后,刷毛的伸展和磨损特征.
- 确定牙刷设计对牙科材料表面粗性和磨损的影响.
主要方法:
- 用树脂复合材料修复的牛牙冠经过了30天,90天和180天的模拟刷牙.
- 面膜和树脂复合材料的表面粗度 (Ra) 在基线和刷后被测量.
- 使用宏摄影和扫描电子显微镜 (SEM) 分析了磨损指数和磨损率.
主要成果:
- 随着时间的推移,树脂复合材料的表面粗度在特定的牙刷 (SlimSoft,Pro Cuidado,Carbon,CS3960) 上显著增加.
- 在使用Pro Cuidado和CS5460后,长时间的刷毛后,面粗度显著增加.
- 碳牙刷显示出最高的磨损指数变化,而CS5460,碳和SlimSoft显示出较高的磨损率,表面粗度变化较少.
结论:
- 牙刷的选择显著影响了树脂复合材料和质的磨损和表面粗度.
- 牙刷带有较高的刷毛量和较窄的丝径可能会导致更多的磨损,但表面粗度变化较少.
- 需要仔细考虑牙刷的特性,以尽量减少牙修复和牙结构的阳性损伤.

01:23Abrasion Resistance of Concrete
81
Abrasion resistance is an essential characteristic of concrete that determines its durability and longevity under various wear conditions. Concrete surfaces are vulnerable to different types of abrasion. For instance, surfaces may wear down due to the constant movement of vehicles or be eroded by solids carried in water, as seen in concrete canal linings. Specific tests are conducted to measure the abrasion resistance of concrete.

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
