Mineral matrix in dentin

The **mineral matrix in dentin** refers to the inorganic, mineralized component of dentin, a hard tissue in teeth found beneath the enamel and surrounding the dental pulp. This matrix is composed primarily of **hydroxyapatite** crystals (calcium phosphate), which account for approximately 68–70% of dentin by weight, providing hardness and rigidity[1][3][4][5]. The mineral phase is deposited within a framework of collagen type I and smaller amounts of other proteins, which together form the organic matrix[1][3][5][8]. The precise organization and mineralization of the matrix are critical for tooth function and resilience. While essential for dentistry and dental research (such as in biomaterials or regenerative studies), **the mineral matrix in dentin is not a drug target, receptor, or defined molecular species**—it is a composite structural feature[1][3][4][5]. **Note:** This entry is marked as *is_incorrect: true*, because "Mineral matrix in dentin" is not a molecular target, protein, or classic therapeutic entity, but a descriptive term for a part of tissue composition. It cannot be targeted by drugs or mapped to classic molecular/structural target categories.
