概括

银二胺化物 (SDF) 的每周两次应用比单次应用更有效地防止质侵蚀. 然而,这种效率的提高伴随着牙变色的风险更大.

科学领域:

牙科材料科学牙科材料科学
预防性牙科预防性牙科
皮肤病学皮肤病学皮肤病学

背景情况:

牙面膜侵蚀是一个重要的临床问题.
银胺化物 (SDF) 是一种有前途的药物,可以预防牙腐烂和侵蚀.
优化SDF应用程序协议对于最大化好处和最小化副作用至关重要.

研究的目的:

为了比较银二胺化物 (SDF) 每周一次或两次局部应用在防止乳液侵蚀方面的疗效.
为了评估不同SDF应用频率的变色效应.

主要方法:

人体质块被分为四组:每周两次SDF,一次SDF,每天化/氨基化 (SNF) 和脱离离子水 (DW).
乳块经过了14天的侵蚀性挑战.
评估的参数包括微硬度损失,表面损失和颜色变化,使用XRD,EDS,SEM和光谱测量.

主要成果:

与DW组相比,这两个SDF组的微硬度损失和表面损失显著减少.
两周一次的SDF应用导致微硬度损失 (26.6%) 和表面损失 (3.1μm) 比单次SDF应用 (分别为33.6%和3.9μm) 低.
与单个SDF应用组 (4.0 ΔE) 相比,每周两次SDF应用组表现出更大的颜色变化 (7.9 ΔE).

结论:

每周两次施用SDF在防止乳侵蚀方面比一次施用更有效.
虽然在防侵蚀方面更有效,但每周两次SDF应用会导致牙变色的增加.
这些发现支持使用每两周一次的局部SDF应用协议,以加强质侵蚀预防.

关键词:

牙侵蚀造成的牙侵蚀面是用乳进行的.化物是一种化物.唾液皮质是一种唾液皮质.银二胺化物是银的二胺化物.这种化物是化.

Surface Membrane Barriers

Surface Membrane Barriers

The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...
