概括

将草精油添加到组织调节剂中,度为1.77%,可以保持抗真菌性能和可接受的机械强度. 这为患有口腔卫生问题和易受候选菌感染的患者提供了一个有前途的解决方案.

科学领域:

生物材料科学生物材料科学
牙科材料牙科材料
菌类学菌类学是指菌类学.

背景情况:

大切除术患者面临口腔卫生和口腔大候选性感染的挑战.
草精油 (LEO) 具有抗真菌性能,但其对组织调节剂机械性能的影响尚不清楚.

研究的目的:

评估不同草精油度对组织修复剂抗拉强度 (TBS) 和Shore A硬度 (SAH) 的影响.
通过拉曼光谱学确认草精油在组织调节剂中的存在和寿命.

主要方法:

组织调节剂被修改为LEO (1.77%,3.56%,7.17%) 或尼斯塔丁 (抗真菌控制).
在多个时间点 (2小时到30天) 测量了Shore A硬度 (SAH).
对假牙基烯酸树脂的拉伸键强度 (TBS) 进行了测试,拉曼光谱证实了LEO的存在.

主要成果:

与对照组相比,LEO在1.77%的水平在SAH中没有显著差异,但在长达7天的时间内显著下降,但在30天内显著下降.
低利率的1.77%没有显著影响TBS,保持比其他群体更高的值.
随着时间的推移,较高的LEO度 (≥3.56%) 和尼斯塔丁显著降低了TBS和SAH. 拉曼证实LEO的存在持续了14天.

结论:

将1.77%的草精油纳入组织调节剂提供了持续的抗真菌活性.
这种度保持了可接受的机械性能 (SAH和TBS),使其适合用于大切除术患者的临床应用.

Local Anesthetics: Chemistry and Structure-Activity Relationship

Local anesthetics (LAs) are drugs that induce a temporary loss of sensation in a limited body area, preventing pain. Cocaine was the first local anesthetic discovered in the late 19th century. Cocaine is a benzoic acid ester obtained from the leaves of coca shrubs and was often used for its psychotropic effects. Cocaine was first isolated in 1860 by Albert Niemann. Sigmund Freud studied the physiological actions of cocaine. Carl Koller later introduced it into clinical practice in 1884 as a...
