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 prosthetics to enhance integration with surrounding tissues. In dentistry, it is used in toothpaste and mouthwash to remineralize enamel and reduce sensitivity. Additionally, hydroxylapatite is utilized in bone graft materials and scaffolds for tissue engineering to promote bone regeneration and repair. Its ability to support cell growth and adhesion makes it a valuable material in regenerative medicine.
