Enamel
what’s the enamel ?
The enamel is a tissue with a 96% mineral content and 4% organic material and water. The inorganic content of the enamel is a crystalline calcium phosphate, hydroxyapatite, which is also found in bone, calcified cartilage, dentin and cementum. The dissolution of the hydroxyapatite crystals by the action of acids is the cause of dental caries. The chemical nature of the organic material has not been fully elucidated, but it is considered to be of a proteic nature and to contain some polysaccharide material. Due to its high mineral content, the enamel is a hard tissue, a property that enables it to withstand the mechanical forces; furthermore, it is transparent, with a color that varies from a light yellow to grayish white (1)(2)(4).
