Nanostructure of healthy and caries-affected human teeth

The scattering pattern related to the 67-nm signal shows abundance, degree of anisotropy, and orientation of the nanostructures between 57 and 69 nm according to the color wheel. Comparing the spatially resolved collagen-related signal with the total scattering signal of the early stages of caries in human dentin, the authors find that the ceramic parts are affected, but the collagen is unchanged, which may have an important impact on the development of future dental treatments of carious teeth.156
