Hydroxyapatite (HA) is a main inorganic component that is similar to those of natural bone and teeth.
Hydroxyapatite (HA) ([Ca.sub.10][(P[O.sub.4]).sub.6][(OH).sub.2]) is the major available inorganic component with biocompatibility, bioactivity, and osteoconductive properties.
In the experiments that we conducted enamel and hydroxyapatites were subjected to demineralization and remineralization using acids and solutions of different concentrations.
Hydroxyapatite (HAP, [Ca.sub.10][(P[O.sub.4]).sub.6][(OH).sub.2]) is one of the most attractive materials for bone implants because of its compositional and biological similarity to native tissues (Weiner & Addadi, 1997).
Substituted hydroxyapatites for bone repair, Journal of Materials Science: Materials in Medicine, 23(10): 2335-2347.
Some structural changes in bioceramics such as hydroxyapatite may occur after gamma irradiation like an increase in their enthalpy [9].
In particular, bioactive ceramics such as hydroxyapatite (HA) and [??]-tricalcium phosphates ([BETA]-TCP) have excellent osteoconductivity and osteoinduction ability; therefore, their porous structure scaffolds have been widely used as bone substitutes in clinical fields [1,2].
