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 in dental care products, such as toothpaste and mouthwash, to help remineralize enamel and reduce tooth sensitivity. In orthopedics, it is used as a coating for dental implants and bone grafts to enhance integration with natural bone tissue. Additionally, hydroxylapatite is utilized in drug delivery systems, where its porous structure allows for controlled release of medications. It also finds applications in cosmetics, particularly in skincare products, for its ability to improve skin texture and hydration.
