Abstract

The objective of our study is to correlate Fe, Cu, Zn, Pb, Br, Sr, and Mo concentrations in human teeth crown, root, and bone.The samples, teeth from a lower jaw bone and the lower jaw bone itself, were obtained from a 97-yr-old female cadaver. Two hundred milligrams of crown and root of the teeth, and lower jaw bones were fixed to a Kapton film and irradiated with a 3.8-MeV external proton beam from an 8-MV FN Tandem Van de Graaff Accelerator.TheF-test was used to analyze the difference between crown, root, and bone. It resulted in the following: For Fe, Zn, and Pb, the comparison showed significant differences among the three sample populations of tooth crown, root, and bone; for Cu, Br, Sr, and Mo, the comparison showed no significant differences among all three sample populations.Several elements in the samples were highly interrelated.

摘要

我们研究的目的是为了分析人类牙齿冠、根和骨中 Fe、Cu、Zn、Pb、Br、Sr 和 Mo 的浓度。我们从一具 97 岁女性尸体中获取了下颚骨牙齿和下颚骨本身的样本。将 200 毫克的牙齿冠、根和下颚骨固定在 Kapton 膜上，并用 8-MV FN Tandem Van de Graaff 加速器的 3.8-MeV 外部质子束照射。我们采用 F 检验分析牙齿冠、根和骨之间的差异。结果表明：对于 Fe、Zn 和 Pb，牙齿冠、根和骨三个样本群体之间的比较存在显著差异；对于 Cu、Br、Sr 和 Mo，三个样本群体之间的比较没有显著差异。样本中的几种元素高度相关。
