The Role of Nanohydroxyapatite in Remineralization
Introduction Nanohydroxyapatite (nHAp) is a synthetic form of hydroxyapatite, a naturally occurring mineral that constitutes the primary inorganic component of human bone and teeth. Due to its biocompatibility and similarity to natural enamel, nHAp has garnered significant attention in dental care, particularly in the field of remineralization. What is Remineralization? Remineralization is the process by which minerals are redeposited in the enamel layer of the teeth, reversing the damage caused by demineralization. Demineralization occurs when acids produced by bacteria in the mouth erode the enamel, leading to cavities and tooth decay. Remineralization helps restore the lost minerals, strengthening the enamel and preventing further decay. Nanohydroxyapatite in Dental Care Mechanism of Action : nHAp particles are small enough to penetrate the enamel surface and fill microscopic defects. They act as a scaffold, attracting calcium and phosphate ions to rebuild the enamel structur...
