Tooth mineral matrix

The tooth mineral matrix primarily consists of the crystalline mineral hydroxyapatite (Ca₁₀(PO₄)₆(OH)₂), which forms about 95-98% of mature enamel and around 50% of dentin by volume[1][5][8]. This matrix confers hardness and brittleness to the tissues, with highly organized hydroxyapatite crystals arranged into enamel rods, surrounded by trace minerals such as fluoride, magnesium, and strontium, and a minimal organic protein matrix (mainly enamelins and amelogenins in enamel; collagen in dentin)[1][3][5][6]. Enamel, being the most mineralized tissue in the body, acts as a protective outer layer of the tooth, while dentin provides a resilient, shock-absorbing scaffold beneath[1][2][6]. The "mineral matrix" is not directly druggable, but is the substrate for preventive interventions (e.g., fluoride treatment) and is affected in disease states like dental caries and erosion. Because "tooth mineral matrix" does not designate a molecular target, protein, or receptor, it does not fit standard target-based drug development paradigms. The correct canonical forms for research use would be "Enamel" (for basic tooth crown mineral), "Dentin" (for underlying mineralized tissue), or "Hydroxyapatite" (as the mineral phase)[1][5][6].
