The biocompatibility of carbonated apatite can be attributed to the tendency of the carbonate to reduce crystallinity within the apatite structure, thereby increasing its solubility which enhances bone reformation or turnover . Carbonated apatite is also a dominant mineral in phosphorites, natural apatitic rocks found in …

Fluoride reacts with tooth mineral, forming either fluoridated apatite (firmly-bound) or calcium fluoride (loosely-bound). Firmly-bound fluoride, incorporated onto the surface of the crystals of apatite, can reduce the solubility of tooth mineral and hence inhibit demineralization due to acids generated by plaque bacteria. 13
