概括

植物素 (PHS) 减少了在烯酸树脂 (AR) 上粘附的可活微生物. 当与碳酸 (Na2CO3) 结合时,PHS对AR色彩稳定性 (CS) 的影响也很小.

科学领域:

生物材料科学生物材料科学
微生物学微生物学
牙科材料牙科材料

背景情况:

烯酸树脂 (AR) 在牙科中广泛使用,但易受微生物粘附和变色的影响.
表面处理的目的是改善AR特性,包括对微生物殖民和颜色变化的抵抗.

研究的目的:

评估植物素 (PHS) 和碳酸 (SP) 对AR表面微生物的颜色稳定性 (CS),抗粘合效应 (AAE) 和细胞活力的影响.
为了比较PHS和SP处理与控制 (PBS) 和甲 (SH) 对AR表面修饰.

主要方法:

对AR标本进行了酸盐缓冲盐水 (PBS),甲 (SH),PHS或PHS+碳酸 (Na2CO3) 的处理.
在治疗前和治疗后评估了颜色稳定性. 使用微生物殖民地计数和光显微镜来评估粘附的Candida albicans的抗粘附效果和细胞活力.

主要成果:

PHS + Na2CO3 在AR中显示最小的颜色变化,与其他组相比.
在治疗方法之间没有观察到抗粘附效应的显著差异.
与PBS和SH相比,PHS显著减少了粘附的活力微生物的面积.

结论:

PHS有效地减少了在AR表面上粘附的可活微生物.
PHS和Na2CO3的组合表明对AR颜色稳定性的影响很小.
作为一种改善AR抗菌性能的表面处理方法,PHS显示出有前途,而不会影响颜色.

Antimicrobial Effectiveness

Antimicrobial Effectiveness

The effectiveness of antimicrobial agents depends on various factors influencing their ability to eliminate microbial populations. Larger microbial populations require more time for complete eradication, emphasizing the importance of population size analysis when evaluating antimicrobial efficacy.Microbial resistance to antimicrobial agents varies significantly. Highly resilient microorganisms include endospores, gram-negative bacteria, and non-enveloped viruses, while prions are exceptionally...

Hand hygiene

Hand hygiene

Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Gene Regulation in Microbial Communities: Quorum Sensing

Gene Regulation in Microbial Communities: Quorum Sensing

Quorum sensing is a mechanism of bacterial communication that enables coordinated gene expression in response to changes in population density. This facilitates collective behaviors that enhance survival, resource acquisition, and ecological adaptation. This process relies on small signaling molecules called autoinducers that accumulate as bacterial populations grow. When a critical threshold concentration of autoinducers is reached, bacterial cells collectively modify gene expression,...
