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 and...
Tooth Anatomy01:21

Tooth Anatomy

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 grinding food.

Summary

This review links spectral, 3D, and color difference measurements for craniofacial and dental materials. It covers measurement accuracy, precision, and applications in clinical practice and research.

Area of Science:

  • Biomaterials science
  • Optical physics
  • Clinical dentistry

Background:

  • Accurate color measurement is crucial for natural and restorative craniofacial and dental materials.
  • Clinical applications and research rely on precise color specifications.

Purpose of the Study:

  • To bridge the understanding between spectral, 3D, and color difference aspects of color.
  • To review geometrical aspects of color measuring systems.
  • To introduce applications of color measurements in material appearance.

Main Methods:

  • Review of spectral, 3D, and color difference color measurement principles.
  • Evaluation of measurement system accuracy and precision.
  • Consideration of color difference acceptability and perceptibility.
