Quantitative SIMS of Prehistoric Teeth
Biological mineralized tissues, such as dry substance of teeth, consist mainly of apatite. Although the secondary ion spectra of apatite are complex /1,2/, sensitive and quantitative SIMS routines have been established for most elements in biomineralizations, with extensive application chiefly in the odontological field /2,3/. In the hard tissue of enamel and dentine, essentially hydroxy-apatite, numerous impurities and elemental substitutions can be found, some of considerable clinical and/or environmental significance. Also, the apatite structure may locally transform to other phosphates. Nevertheless SIMS has been shown to give reproducible elemental analysis of dental tissues.
