Tooth enamel mineral structure

Tooth enamel mineral structure refers to the physical and chemical composition of the outermost layer of the tooth, which is the hardest and most mineralized tissue in the human body[1][4][6][8]. Tooth enamel is composed of approximately 95–98% inorganic minerals, mainly as hydroxyapatite crystals (a crystalline form of calcium phosphate), as well as 1–2% organic material (mostly specific proteins such as enamelin and amelogenin) and about 4% water[1][3][4]. The hydroxyapatite crystals are organized into rods (or prisms) and interrod enamel, forming a highly ordered, hierarchical structure critical to enamel’s hardness and resilience[1][3][7][8]. Enamel serves as a protective outer covering for the tooth crown, shielding it from physical damage and acid erosion; however, it does not regenerate if lost[4][6]. It is not a canonical therapeutic target like a receptor, enzyme, or molecular drug target, but is rather a structural biological material of clinical interest due to its role in dental diseases such as caries, erosion, and sensitivity[6]. Therefore, "tooth enamel mineral structure" is descriptive of a tissue/material, not a discrete molecule or receptor, and thus is not a drug target in the classical pharmaceutical sense.
