Splet09. jan. 2024 · The crystals range from transparent to translucent, with a vitreous to greasy luster. This mineral is also a biological material. In particular, hydroxylapatite is the main constituent of tooth enamel, and a special form of apatite is found in bone . Enamel is the hardest substance in the human body and contains the highest percentage of minerals (at 96%), with water and organic material composing the rest. The primary mineral is hydroxyapatite, which is a crystalline calcium phosphate. Enamel is formed on the tooth while the tooth develops within … Prikaži več Tooth enamel is one of the four major tissues that make up the tooth in humans and many other animals, including some species of fish.
