What’s the dentin ?
The dentin is a tissue formed of mineral salts and organic material. The mineral salts are calcium salts in the form of hydroxyapatite crystals. The dentin is found to be traversed by innumerable parallel tubules, the dentinal tubules, which contain a substance produced by the stem cell, the odontoblasts. These cells are present both in the pulp and in the dentin, and provide a constant source of dental tissue. Due to its physical properties, dentin has an elastic quality that is important for the correct function of a tooth, as it provides the flexibility necessary to avoid facture of the fragile overlying enamel (1)(2)(4).
