Abstract
A bioactive glass composition comprising one or more glasses comprising Si02, P205 and a fluoride, the Si02 content being less than 40 mole %, the P205 content being at least 4 mole %, and the fluoride content being greater than 1 mole %. The bioactive glass or glass-ceramic can be used in a number of medical applications, including dental applications such as toothpaste.
Claims18
A bioactive glass composition comprising one or more glasses comprising SiO2, P2O5 and a fluoride, the SiO2 content being less than 40 mole %, the P2O5 content being at least 4 mole %, and the fluoride content being greater than 1 mole % and less than 25 mole %, wherein the bioactive glass composition forms fluorapatite instead of hydroxycarbonated apatite (HCA) and suppresses formation of fluorite (CaF2) at the expense of fluorapatite when immersed in a body fluid or in simulated body fluid.
