Fig. 8

Processed scanning SAXS signal from specimens obtained from eight teeth, listed in Table 1. Strong similarity of the overall organization of tooth nano-anatomy is found. The left column shows the orientation of nanostructures in the range from 8 to 20 nm. The right column combines orientation (color-wheel), scattering intensity (color brightness) and anisotropy (color saturation) of the collagen-related signal. The orientation of the scattering signal (left column) is perpendicular to the nanostructure orientation, while the orientation of the collagen-related signal (right column) is parallel to the fibers
