On a quantitative basis, the most important of the calcium phosphates (Table 11) is an apatite closely related to hydroxylapatite (HAP). This is better described as an impure carbonate-containing apatite (CO3Ap) and forms the inorganic component of bones and teeth. Table 11 also includes calcium phosphates (including two pyrophosphates) that occur in pathological mineralizations and those that are used for the repair of mineralized tissues. Unlike the well-controlled process of normal mineralization in bones and teeth (see later), pathological mineralizations are usually poorly controlled with the result that several calcium phosphates may occur together.
