Dentin tubules and enamel mineral matrix

Dentin tubules and the enamel mineral matrix are the fundamental structural elements of the tooth, serving as the primary substrates for dental therapeutics. Enamel is the most highly mineralized tissue in the human body, composed mainly of hydroxyapatite crystals arranged in a complex prismatic structure that provides extreme hardness and protection (NIH, 2023). Dentin lies beneath the enamel and is permeated by thousands of microscopic dentin tubules, which facilitate the transmission of stimuli to the dental pulp via fluid movement, a process described by the hydrodynamic theory of dental pain (StatPearls, 2023). These structures are the focus of treatments for dental caries, erosion, and hypersensitivity. Pharmacological interventions typically involve the application of minerals like fluoride to strengthen the enamel matrix or the use of tubule-occluding agents to block sensory pathways (PubMed, 2022). Understanding the interaction between these mineralized tissues and therapeutic ions is critical for developing effective restorative and preventive dental materials.
