概括

用盐水或80%乙醇进行最终灌并没有改善AH Plus或BioRoot RCS密封器的根管密封性. 两种最终冲洗溶液都没有在内牙治疗中防止泄漏的标准协议上提供显著的好处.

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

背景情况:

牙周灌清洁,消毒,并使根管牙条件为堵塞.
评估最终的灌解决方案对于优化根管密封和长期治疗成功至关重要.

研究的目的:

评估使用环氧树脂 (AH Plus) 和酸水泥 (BioRoot RCS) 密封剂时,是否用盐水或80%乙醇进行最终灌可以提高根管密封性.
为了比较两种当代内牙密封器的密封效果,遵循不同的最终灌协议.

主要方法:

提取的人类牙经历了仪器仪表和闭塞,使用AH Plus或BioRoot RCS.
密封体特定的灌方案包括二化,1-基乙烯-1,1-二酸和乙烯基二胺三酸 (EDTA).
牙在堵塞和泄漏评估之前用盐酸,80%的乙醇进行了最后冲洗,或者没有最后冲洗 (控制) 使用Rhodamine B.

主要成果:

密封剂类型显著影响了顶点染料透率 (P < 0.05),AH Plus显示出稍微更好的密封.
最后的冲洗方案 (盐水或乙醇) 并没有显著影响根管密封性 (P > 0.05).
泄漏模式不同:AH Plus显示了密封器-牙接口的泄漏,而BioRoot RCS在密封器-牙接口和密封器-牙接口都有泄漏.

结论:

在测试条件下,用盐水或80%乙醇进行最终灌,对于改善AH Plus或BioRoot RCS的根管密封性没有明显的好处.
密封器类型的选择是影响根管密封效率的更关键因素,而不是添加盐水或乙醇最终冲洗.

Solvating Effects

Solvating Effects

An understanding of the solvating effect helps rationalize the relation between solvation and acidity of the compound. In addition, this also explains the relative stability of conjugate bases for compounds with different pKa values. This lesson details, in-depth, the principle of solvating effects. The strength of an acid and the stability of its corresponding conjugate base are determined using pKa values. This observed relationship is a consequence of solvation, which is the interaction...

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.
