| Research Abstract |
Trace elements in enamel of deciduous teeth were investigated in order to assess the fatal environment. Deciduous teeth include both pre-natal formed enamel and post-natal formed enamel. They are distinguished by neonatal line. We established the analytical method using micro-PIXE, by which trace elements including pre-and post-natal enamel are measured without destruction of their structure. Some trace elements, Na, Mg, Zn, Sr, and Fe were in prenatal enamel with various concentrations.
