The perception of tooth colour is multi-factorial. Reflection and absorption of light by the tooth can be influenced by a number of factors including specular transmission of light through the tooth; specular reflection at the surface; diffuse light reflection at the surface; absorption and scattering of light within the dental tissues; enamel mineral content; enamel thickness; dentine colour ...
The dentino-enamel junction is thought to be a scalloped structure, which has occurred as an exaptation of the epithelial folding undergone during ontogeny. This scalloped exaptation has then provided stress relief during mastication and a reduction in dentin-enamel sliding and has, thus, not been selected against, making it an accidental ...
The veneers used are primarily woods, but may include bone, ivory, turtle-shell (conventionally called "tortoiseshell"), mother-of-pearl, pewter, brass or fine metals.. Marquetry using colored straw was a specialty of some European spa resorts from the end of the 18th ce
