Calcium phosphates have important role in biological and pathological
mineralization. While only one of calcium phosphates, carbonate apatite,
represents the main mineral component of teeth and bones, octacalcium
phosphate, calcium hydrogenphosphate dihydrate and beta-tricalcium phosphate
occur in pathological deposits. From the stand-point of chemists, processes
of biological and pathological mineralization could be considered as
deposition of inorganic phase within organic matrix, i.e. formation of
inorganic-organic composites. Although this approach is very simplified at
first glance, it allows clarification of important issues related to
biomineralization (e.g. what is the role of individual components of organic
matrix in the emerging solid tissue), and design and preparation of new
materials for hard tissue regeneration (e.g. process of transformation after
implantation). The importance of investigation about calcium phosphates will
be presented through the overview of basic physico-chemical reactions related
to the formation and transformation of biologically relevant calcium
phosphates and their interaction with various organic additives in the
laboratory.
