Abstract:
The anatomy of human teeth reflects its usage. Spatially resolved X-ray scattering permits quantitative studies of the characteristic arrangement of the anisotropic calcium phosphate crystallites and the collagen fibers within the hard tissues of the crown. The present study summarizes the distinctive nanometer-sized anatomical features of the tooth hard tissues including their interface taking advantage of spatially resolved synchrotron radiation-based small-angle X-ray scattering. The comparison of slices from eight teeth indicates a long-range organization of tooth nanostructures.

Tooth Anatomy
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.
Teeth
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...
Oral Cavity
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...
