Demineralization process at enamel-dentin interface

The demineralization process at the enamel-dentin interface involves the loss of mineral ions (primarily calcium and phosphate) from the hydroxyapatite crystals that make up tooth enamel and dentin. This process is driven by acid production from oral biofilm bacteria as they metabolize dietary carbohydrates, leading to a drop in pH below critical levels (5.5 for enamel, 6.2 for dentin). The acidic environment facilitates the dissolution of these minerals, resulting in weakening and eventual formation of white spot lesions and cavities. Remineralization is the natural repair mechanism wherein minerals are restored to the crystals under neutral pH conditions, with fluoride and other agents acting to enhance this process or inhibit further mineral loss. The balance between demineralization and remineralization determines the health of the tooth structure and its susceptibility to caries and erosion. In summary, "Demineralization process at enamel-dentin interface" is a well-characterized biochemical and pathological process—not a molecular or pharmacological target. For molecular targeting, components such as hydroxyapatite crystals, enamel matrix proteins, or specific matrix metalloproteinases involved in enamel and dentin remodeling would be appropriate.

Fluoride: Incorporates into demineralized enamel as fluorapatite, which is more resistant to acid-induced demineralization. TCP: Delivers calcium and phosphate to aid remineralization. L-arginine: Improves pH homeostasis and helps remineralization. Propolis: Enhances absorption of calcium and phosphate, increasing remineralization.
