Trace element distribution in human teeth by x-ray fluorescence spectrometry and multivariate statistical analysis [PDF]
arXiv, 2014 X-ray fluorescence spectrometry (XRFS) was used as a multielement method of evaluation of individual whole human tooth or tooth tissues for their amounts of trace elements. Measurements were carried out on human enamel, dentine, and dental cementum, and some differences in tooth matrix composition were noted.
