概括
牙科学生在视觉色彩测定 (VCD) 中表现出颜色偏差,无论使用何种参考尺度. 在牙科教育中早期的VCD培训可以防止阴影误判和昂贵的重制.
科学领域:
- 牙科教育 牙科教育
- 颜色科学 颜色科学
- 恢复性牙科 恢复性牙科
背景情况:
- 视觉色彩确定 (VCD) 在牙科中至关重要,但需要专业知识.
- 学生的VCD准确性可能会受到使用的参考尺度的影响.
- 需要使用不同尺度对VCD准确性的客观评估.
研究的目的:
- 用两个不同的参考尺度评估牙科学生的颜色确定偏差.
- 为了比较VITA-classical (VC) 和3D-Master-Toothguide (3DM_TG) 标尺对VCD的准确性.
- 为了确定特定的参考尺度是否可以提高学生的视频记录器准确性.
主要方法:
- 参与者在使用VC和3DM_TG尺度的9个模板上进行了VCD.
- 颜色距离 (ΔEab) 使用CIELAB 2000参数 (LCh°) 进行计算.
- 非参数统计方法 (中位数,四分位数) 和学生的t测试分析了结果 (α = 0.05).
主要成果:
- 在学生的VCD中观察到显著的颜色偏差 (p < 0.001),无论尺度如何.
- 3DM_TG尺度显示 ΔE00 的中位数为 -1.49,而VC 尺度的中位数 ΔE00 是 0.00.
- 在两个参考尺度之间,色彩和色彩偏差是可比的.
结论:
- 牙科学生的VCD准确性并没有被VC或3DM_TG参考尺度显著改善.
- 颜色色调和色调的偏差在不同的参考尺度上是一致的.
- 建议在牙科教育的早期实施VCD培训,以最大限度地减少阴影误判并降低重制成本.

Teeth

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...

Color Vision
584
Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.

Tooth Anatomy
481
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...
