Used in dental and orthopedic applications as a bioactive component in bone cements and restorative materials. Promotes bone regeneration by forming hydroxyapatite when in contact with physiological fluids. Commonly found in calcium phosphate cements that harden in situ to support bone repair. Also utilized in dental composites for its ability to release calcium ions, aiding in remineralization of tooth structure. Exhibits good biocompatibility and osteoconductivity, making it suitable for use in scaffolds for tissue engineering.
