1. tooth enamel

   Tooth enamel is the hard, outer layer of the tooth that serves to protect against tooth decay. It is the visible part of the tooth and is the hardest tissue in the human body, consisting mainly of mineral, primarily hydroxyapatite. Despite its strength, it can still be damaged by decay, trauma or wear over time.

1. Tooth enamel

   Tooth enamel, along with dentin, cementum, and dental pulp is one of the four major tissues that make up the tooth in lobe finned fish and tetrapods. It is the hardest and most highly mineralized substance in the human body. Tooth enamel is also found in the dermal denticles of sharks. It is the normally visible dental tissue of a tooth. It covers the anatomical crown and must be supported by underlying dentin. Enamel is 96% inorganic mineral, with water and organic material composing the rest. In humans, enamel varies in thickness over the surface of the tooth, often thickest at the cusp, up to 2.5 mm, and thinnest at its border with the cementum at the cementoenamel junction. The normal color of enamel varies from light yellow to grayish white. At the edges of teeth where there is no dentin underlying the enamel, the color sometimes has a slightly blue tone. Since enamel is semitranslucent, the color of dentin and any material underneath the enamel strongly affects the appearance of a tooth. The enamel on primary teeth has a more opaque crystalline form and thus appears whiter than on permanent teeth. Enamel's primary mineral is hydroxyapatite, which is a crystalline calcium phosphate. The large amount of mineral in enamel accounts not only for its strength but also for its brittleness. Tooth enamel ranks 5 on Mohs hardness scale and a Young's modulus of 83 GPa. Dentin, less mineralized and less brittle, 3–4 in hardness, compensates for enamel and is necessary as a support. On radiographs, the differences in the mineralization of different portions of the tooth and surrounding periodontium can be noted; enamel appears more radiopaque than either dentin and pulp since it is denser than both, both of which appear more radiolucent.

1. Christophe Snoeck:

   Cremation destroys all organic matter [ including DNA ] but all the inorganic matter survives and we know, from the study of tooth enamel, that there is a huge amount of information contained in the inorganic fraction of human remains.
