Abstract
The purpose of this study
was to investigate the effect of trace metals and fluoride on structural
disorder in carbonated apatites and to consider the relevance of the results to
dental apatite (enamel). Synthetic carbonated apatites were precipitated in the
presence of low levels of zinc, magnesium, strontium, iron and fluoride.
Crystal imperfection, as indicated by X-ray peak half-widths, was altered
markedly by the substituents. Fluoride alone was effective and zinc- fluoride
was the most effective combination in compensating for disorder caused by
carbonate inclusion. These results show that disorder induced by carbonate
inclusion can be modified greatly by appropriate elements. Trace-element
inclusions may therefore markedly affect dental enamel reactivity. Carbonate
content alone cannot be used as an indicator of the reactivity of apatite or of
the potential susceptibility of dental enamel to caries.
