概括
两种新的白银化物产品有效地阻止了有特殊需求的成年人的. 两者都在三个月后导致了明显的病变变黑,类似于银胺化物,影响了患者的接受度.
科学领域:
- 牙科 牙科是指牙科的专业.
- 皮肤病学 皮肤病学 皮肤病学
- 牙科材料科学 牙科材料科学
背景情况:
- 银胺化物 (SDF) 是有效的脏停止,但导致牙变色,减少患者接受.
- 正在研究替代银化物 (AgF) 配方,以减轻美学方面的担忧.
研究的目的:
- 为了评估用两种新银化物 (AgF) 产品治疗的病变的颜色变化.
- 为了将这些颜色变化与脏活动和细菌负载相关联.
- 评估这些AgF产品在阻止有特殊需要的成年人平滑表面的疗效.
主要方法:
- 在有特殊需求的成年人中,采用了分口研究设计.
- 两种AgF产品,AgF/化 (KI) 和AgF/化 (SnF2),被应用1分钟,以光滑表面的病变.
- 数字图像分析用于量化基线时的颜色变化 (delta-E) 和亮度,治疗后立即,并在3个月后.
主要成果:
- 与未经处理的牙结构相比,两种AgF产品都显著改变了病变颜色,即刻和3个月后 (P < 0.0001).
- AgF/SnF2导致了即时的暂时变黑,而AgF/KI则产生了即时的黄色沉积物.
- 这两种产品在3个月后导致病变显著变黑 (P = 0.0009;P = 0.0361),它们之间没有显著差异 (P = 0.506).
- 响应的病变在AgF应用后立即表现出更明显的颜色变化 (P = 0.002;P = 0.024).
结论:
- 这两种新型AgF配方都有效地阻止了有特殊需要的成年人的光滑表面.
- 虽然最初的外观不同,但两种AgF产品在3个月后导致可比的病变变黑.
- 患者应被告知长期染色的可能性,类似于SDF.

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
