概括
结合氧化 (Ca ((OH) 2) 与二化 (NaOCl) 作为一个访问间的根运河敷料显著增强了抗菌作用. 与盐水相比,这种组合有效降低了牙上角牙周炎的牙中的微生物负载.
科学领域:
- 牙周内科医院 牙周内科医院 牙周内科医院
- 微生物学 微生物学
- 生物化学 生化学
背景情况:
- 牙周炎 (apical periodontitis) 在牙周内面临着一个重大的挑战.
- 有效的管内消毒对于治疗成功至关重要.
- 目前正在研究用于根管治疗的新型抗菌药物策略.
研究的目的:
- 为了评估氧化 (Ca(OH) 2与甲 (NaOCl) 结合的添加剂的抗菌疗效,作为访问间的根运河敷料.
- 为了比较通过Ca(OH)2/NaOCl泥与Ca(OH)2/盐水泥实现的微生物减少.
- 评估对周围炎症标志物的影响.
主要方法:
- 一项随机对照临床试验,涉及患有脉死和牙周围炎的患者.
- 根管道被仪器化并用3%的NaOCl灌.
- 访问间的敷料由Ca ((OH) 2泥与3%的NaOCl (试验) 或盐水 (控制) 混合而成.
- 收集了微生物样本和周围液体,以分析无氧生长和MMP-9水平.
主要成果:
- 与Ca(OH) 2/NaOCl组 (6%) (p<0.001) 相比,Ca(OH) 2/盐酸组 (40%) 的微生物清除率显著更高.
- 化学机械制剂显著减少了殖民地形成单位 (CFU),但没有完全消除微生物.
- 试验组和对照组之间,周周液中的矩阵金属蛋白酶-9 (MMP-9) 水平相似.
结论:
- 一种NaOCl/Ca(OH) 2结合的根运河敷料在一次性顶牙牙周炎中表现出对细菌的优越抗菌活性.
- 这种增强的消毒可以在没有明显增加周围炎症的情况下实现.
- 这些发现支持使用NaOCl增强的Ca(OH) 2敷料来改善内牙消毒.

Factors Affecting Solubility
36.5K
Compared with pure water, the solubility of an ionic compound is less in aqueous solutions containing a common ion (one also produced by dissolution of the ionic compound). This is an example of a phenomenon known as the common ion effect, which is a consequence of the law of mass action that may be explained using Le Chȃtelier’s principle. Consider the dissolution of silver iodide:

Hydration of Cement
769
Hydration of cement is a chemical reaction between cement particles and water. This process occurs primarily through two mechanisms: through-solution and topochemical. In the through-solution process, anhydrous compounds dissolve into their constituents, hydrates form in the solution, and then precipitate from the supersaturated solution. The topochemical process involves solid-state reactions at the cement particle surface. The through-solution process dominates the topochemical process at the...

Hand hygiene
5.5K
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.
