概括
磨的 (MZ) 比未经处理的添加剂制造的 (AMZ-0) 有较少的Streptococcus mutans粘附. 与AMZ-0相比,AMZ (AM:50) 的设计孔隙性降低了细菌粘附,但与MZ相比没有显著的降低.
科学领域:
- 生物材料科学
- 牙科材料科学
- 微生物学
背景情况:
- 在牙科修复中越来越多地使用,需要减少微生物粘附的策略,特别是Streptococcus mutans,这是斑块和二次的关键因素.
- 增材制造的 (AMZ) 提供了设计灵活性,包括可控的孔隙性,这可能会影响细菌粘附.
- 了解不同制方法上的微生物粘附对于预防牙至关重要.
研究的目的:
- 为了比较Streptococcus mutans在添加制造的 (AMZ) 和磨 (MZ) 上的粘附性.
- 评估设计孔径对AMZ中的细菌粘附的影响,以优化表面处理.
- 评估 AMZ 具有可控毛孔性的牙修复材料的潜力,其细菌粘附性降低.
主要方法:
- 制造了60个圆盘,15个是通过添加制造的,有50μm的孔隙 (AM:50),15个是通过添加制造的,没有孔隙 (AMZ-0) 和15个是通过磨砂制造的 (MZ).
- 磁盘暴露在Streptococcus mutans中24小时,并使用殖民地形成单位 (CFU) 数量来量化附着细菌.
- 测量了表面粗度,并进行了统计分析 (ANOVA),显著度为α=0.05.
主要成果:
- 与未经处理的添加剂制造的 (AMZ-0) 相比,磨砂 (MZ) 的粘附性明显较低 (p < 0.001).
- 与AMZ-0相比,增材制造的孔隙性 (AM:50) 的细菌粘附性降低.
- 在AM:50和MZ之间没有发现细菌粘附的统计学意义上的差异.
结论:
- 与未经处理的添加剂制造的 (AMZ-0) 相比,磨砂 (MZ) 对Streptococcus mutans的附着性具有更高的抵抗力.
- 与未经处理的AMZ相比,增材制造的孔性 (AM:50) 有效地降低了细菌的附着性.
- 控制多孔性的AMZ为牙科修复提供了有前途的替代方案,其微生物粘附性与磨砂相比较.

Additives and Fillers in Concrete
493
Additives and fillers are integral to enhancing the properties of concrete. Pozzolans and blast-furnace slag are additives or admixtures due to their reactions with calcium hydroxide released during cement hydration. Fillers, which are finely ground and similar in fineness to Portland cement, improve concrete attributes such as workability density, and reduce capillary bleeding or cracking. Some fillers possess hydraulic properties or participate in benign reactions within the cement paste.

Waterproofing and Anti-Bacterial Admixtures in Concrete
329
Concrete's susceptibility to water absorption is due to the capillary action within the pores of its hydrated cement paste. This action draws water in, creating the need for waterproofing admixtures to prevent such penetration. The efficacy of these admixtures is contingent upon the water pressure, with variations arising from different conditions such as rain, capillary rise, or hydrostatic pressure in structures intended to hold water.

Biofilms
2.1K
Biofilms are complex communities of microorganisms encased in a self-produced extracellular polysaccharide matrix attached to surfaces. These microbial consortia can include single or multiple species, providing enhanced survival benefits by forming organized, multilayered structures.The formation of biofilms occurs through four key stages: attachment, colonization, development, and dispersal.During attachment, free-swimming planktonic cells adhere to a surface, often facilitated by...

Microbes in Beverage Production
298
Alcoholic beverages such as wine, beer, and spirits are the products of microbial fermentation processes that transform simple sugars into ethanol and a wide array of complex flavor compounds. These transformations rely on the metabolic activities of specific yeasts and bacteria, which are selected and controlled to yield the desired beverage characteristics.Wine Fermentation and MaturationWine production begins with the crushing of grapes to release juice and pulp, forming a must that is...

Microbes in the Production of Fermented Foods
327
Lactic acid bacteria (LAB) and molds are instrumental in fermenting plant-based foods to enhance preservation and ensure year-round availability. These microbial processes convert plant carbohydrates into organic acids and other metabolites that inhibit spoilage organisms and contribute to the sensory qualities of the final product.In sauerkraut production, cabbage goes through a microbial succession that starts with cocci such as Leuconostoc mesenteroides. These microbes begin fermentation by...

Development of the Oral Microbiota
65
The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
