Abstract

Synchrotron micro X-ray fluorescence has been used to study differences in the trace element concentration between the dentine and cementum rings of human teeth. The results show that metals such as zinc are concentrated in the cementum rings. This suggests that if the rings are deposited annually a temporal record of metal exposure may be extracted from this material.

Notes

The Royal Society of Chemistry chose to feature this article as an innovative application of synchrotron XRF: http://www.rsc.org/publishing/chemscience/volume/2004/10/ch0041000c74a.asp
