Hydroxylapatite is widely used in biomedical applications due to its biocompatibility and similarity to the mineral component of bones and teeth. It is commonly employed as a coating for dental implants and orthopedic prostheses to enhance integration with bone tissue. In dentistry, it is used in toothpaste and dental fillings to help remineralize enamel and reduce sensitivity. Additionally, hydroxylapatite is utilized in bone graft materials to promote bone regeneration and repair in cases of fractures or defects. It also finds applications in drug delivery systems, where it serves as a carrier for controlled release of therapeutic agents.
