概括

通过牙植入物支柱的微生物泄漏因支柱类型而异. 带有UCLA支柱的形植入物显示出最高的泄漏,而带有TiBase支柱的圆柱体植入物显示出最低的泄漏.

科学领域:

牙科植入物学牙科植入物学
微生物学微生物学
生物材料科学生物材料科学

背景情况:

植入物 - 支架接口是牙科植入物中微生物污染的潜在途径.
了解微生物泄漏对于长期的植入成功和患者健康至关重要.

研究的目的:

为了评估和比较微生物泄漏通过植入物-支柱接口的牙科植入物与不同的莫尔斯缩支柱.
在模拟的临床条件下,评估各种支柱类型对细菌侵入的影响.

主要方法:

准备了56个具有四种不同支柱配置的牙植入物样本.
在热力或热循环后,使用基因组计数通过Checkerboard DNA-DNA杂交来评估微生物泄漏.
植入物 - 支架接口被沉浸在唾液中作为污染源.

主要成果:

在循环后,在组之间观察到总基因组计数的显著差异,泄漏的顺序是:圆植入物-UCLA支柱 > 圆植入物-通用支柱 > 圆植入物-TiBase支柱 > 圆柱植入物-TiBase支柱.
个体细菌计数也显示了群体之间的显著差异 (p < 0.05).
支架类型显著影响了总微生物泄漏和特定细菌物种的存在.

结论:

牙科植入物中使用的支柱类型在通过植入物-支柱接口的微生物泄漏中发挥着重要作用.
与其他配置相比,尖的支柱,特别是与UCLA连接的支柱,显示出较高的微生物泄漏率.
这些发现强调了支柱选择在防止细菌污染和确保植入物稳定性方面的重要性.

Bacterial Signaling

Bacterial Signaling

Bacterial signaling can occur within bacteria (intracellular) or between bacteria (intercellular). At times, a group of bacteria behaves like a community. To achieve this, they engage in quorum sensing, the perception of higher cell density that causes changes in gene expression. Quorum sensing involves both extracellular and intracellular signaling. The signaling cascade starts with a molecule called an autoinducer (AI). Individual bacteria produce AIs that move out of the bacterial cell...
