概括

在接触电子烟气溶后,评估了牙陶颜色的变化. 虽然一些材料表现出显著的变化,但其他材料仍然在临床上是可以接受的,这表明材料依赖于耐久性. 传统的吸烟导致更大的变色.

科学领域:

牙科材料科学牙科材料科学
生物材料研究生物材料研究
恢复性牙科恢复性牙科

背景情况:

牙科陶广泛用于美学修复.
电子烟 (EC) 气溶对牙陶颜色稳定性的影响尚不清楚.
评估颜色变化对于保持恢复性牙科的美学结果至关重要.

研究的目的:

评估五种常见的牙科陶材料在接触电子烟 (EC) 气溶时的色彩稳定性.
为了比较不同类型的陶和不同数量的膨胀,颜色的变化.
为了确定观察到的颜色变化的临床可接受性.

主要方法:

五种牙科陶 (PEmax,LEmax,LZr,MZr,PFM) 被制备和老化.
样品被暴露在来自高消耗设备和补充产生的EC气溶中,模拟了口内条件.
颜色变化 (ΔE) 用光谱测量以最多1500次的间隔进行测量.

主要成果:

所有测试的陶在EC气溶暴露后都表现出一定程度的颜色变化.
像LEmax,LZr和MZr这样的材料在1500次吹气时显示出显著的颜色变化.
PEmax和PFM分别表现出临床上可接受的和微不足道的颜色变化.

结论:

牙陶的色彩稳定性取决于材料,并受到EC气溶气泡数量的影响.
在某些牙科陶 (LEmax,LZr,MZr) 中,由于EC气溶暴露,可能会发生审美显著的颜色变化.
从EC气溶中观察到的颜色变化不如传统烟草吸烟的颜色变化明显.

Stimulants

Stimulants

Stimulants are substances that enhance neural activity and elevate dopamine levels in the brain, leading to their highly addictive nature. These drugs include cocaine, amphetamines, MDMA, caffeine, and nicotine, each with distinct mechanisms of action and varied health implications.
Cocaine can be administered via snorting, injection, or smoking. It primarily functions by blocking the reuptake of dopamine, resulting in a euphoric high characterized by an intense sensation of happiness and...
