Dental Substrates

Dental substrates refer to the mineralized tissues that constitute the human tooth, specifically enamel, dentin, and cementum. Enamel is the highly mineralized outer layer, composed of approximately 96% inorganic material, mainly hydroxyapatite crystals, which provides a hard, protective surface for mastication (Source: StatPearls, Anatomy, Head and Neck, Tooth Enamel). Dentin, located beneath the enamel, is a porous, bone-like tissue containing microscopic tubules and a higher organic content, primarily Type I collagen (Source: PubMed, Dentin: structure, composition and mineralization). While not traditional therapeutic targets such as receptors or enzymes, these substrates are the primary sites for dental interventions; for instance, fluoride ions interact with the hydroxyapatite in enamel to form fluorapatite, which is more resistant to acid dissolution (Source: NIH, Fluoride: Fact Sheet for Health Professionals). Pathological degradation of these substrates leads to conditions like dental caries and dentin hypersensitivity, where the exposure of dentinal tubules allows external stimuli to reach the pulp (Source: PubMed, Dentin hypersensitivity: recent trends in management). Consequently, therapeutic strategies often involve the remineralization of these substrates or the application of adhesive materials to restore structural integrity.
