概括

用低化 (NaOCl) 或氧化 (CHX) 灌孔孔孔损害了矿物三氧化聚合物 (MTA) 的密封. 赫西丁 (CHX) 对MTA产生更大的负面影响.

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
恢复性牙科恢复性牙科

背景情况:

孔穿孔是具有挑战性的临床情况,需要有效的密封.
矿物三氧化物聚合物 (MTA) 是修复孔的常见材料.
灌溶液与MTA的密封能力之间的相互作用需要进一步研究.

研究的目的:

评估5.25%的低 (NaOCl) 和2%的 (CHX) 对ProRoot MTA的密封能力的影响.
为了比较NaOCl和CHX灌对MTA边缘密封的作用,使用染料透 (DP).

主要方法:

用ProRoot MTA.封闭了36个带有模拟孔的下牙.
样品用5.25%的NaOCl,2%的CHX或没有溶液 (对照) 灌24小时.
边缘染料泄漏被评估使用2%的甲蓝和立体显微镜.

主要成果:

在两组之间观察到染料透率 (DP) 的显著差异 (p < 0.01).
对照组的泄漏率低于NaOCl和CHX组.
赫西丁 (CHX) 组的泄漏率明显高于NaOCl组 (p < 0.01).

结论:

5.25%的NaOCl和2%的CHX都会对ProRoot MTA的边际密封能力产生负面影响.
与NaOCl相比,2%的CHX对MTA密封具有更不利的影响.
临床医生应谨慎使用NaOCl或CHX在MTA应用后,由于密封性受到损害,在孔穿孔中使用.

Microbial Bioremediation of Uranium

Microbial Bioremediation of Uranium

Microorganisms play a critical role in the transformation and immobilization of uranium in contaminated environments through four main pathways: bioreduction, biosorption, bioaccumulation, and biomineralization. These mechanisms reduce uranium’s toxicity and prevent its migration through groundwater systems, offering sustainable approaches for in situ bioremediation.Bioreduction of UraniumBioreduction is driven by anaerobic bacteria such as certain strains of Geobacter and Shewanella, which use...

Microbial Leaching

Microbial Leaching

Microbial leaching, also known as bioleaching, is an environmentally favorable method for extracting metals from low-grade ores using specific microorganisms. This biotechnological approach is particularly valuable for mining operations targeting copper, gold, and uranium, where traditional extraction methods may be economically or environmentally impractical.Copper Leaching and Microbial CatalysisIn copper bioleaching, crushed ore is arranged into heaps and irrigated with a dilute sulfuric...
