Determination of Trace Elements in Carious Teeth by ICP-AES
Trace elements such as Zn,Fe,Cu,Sr,Mg,Cr,Al and Pb in carious teeth and none carious teeth of enamel and dentin were determined by inductively coupled plasma atomic emission spectrometry(ICP-AES).The sample was completely dissolved by HNO3-HClO_4.The range of relative standard deviation is 1.1%-2.7%and the range of recovery is 90.0%-106.7%.The contents of Zn,Fe,Cu and Sr in carious teeth were lower than in none carious teeth.The contents of Mg,Cr,Al and Pb in carious teeth were higher than in none carious teeth.Trace elements in teeth are a factor to indicate sorts of teeth diseases.The study provides experimental data of trace elements of carious teeth,and provides useful data for dental department in preventing and curing the decayed teeth.
