摘要：

Determination of rare earth and trace elements in teeth enamel was studied by inductively coupled plasma mass spectroscopy. The sample was completely dissolved by HNO3-H2O2. The range of precision is 0.50%-6.79% given by the relative standard deviation and the range of accuracy is 94.45%-104.78% obtained by measuring standard recovery rate. The above data satisfied completely the requirements of biological sample. While this study provides experimental data of rareearth and trace elements of teeth enamel for carious teeth and none carious teeth of human for prevention and cure of decayed tooth. A reasonable method is provided for mouth medicine research.
