Abstract

Dentine samples were prepared from 123 permanent teeth and Co, Cu, Mg, Mn, Ni, Pb, Sr and Zn concentrations were determined with an atomic absorption spectrophotometer. Relations between the cations were evaluated using the correlation matrix and multiple linear regression analysis. When the simultaneous variation of the concentrations of all determined elements was taken into consideration, the following statistically significant positive correlations were found: Cu-Mn, Mn-Co, Ni-Mn and Sr-Ni. A weaker correlation was obtained between Ni and Mg and between Ni and Pb. The only negative correlation was between Sr and Pb, but the explanation percentage in the regression model was low. The results indicated that the chemically and physically related elements Co, Cu, Mn and Ni formed positive correlations. Sr-Ni and Mn-Cu relationships were similar to those reported for human cancellous bone.

摘要

从123颗恒牙制备牙本质样本，并用原子吸收分光光度计测定钴、铜、镁、锰、镍、铅、锶和锌的浓度。使用相关矩阵和多元线性回归分析评估阳离子之间的关系。当考虑所有测定元素浓度的同时变化时，发现以下具有统计学意义的正相关：铜 - 锰、锰 - 钴、镍 - 锰和锶 - 镍。镍与镁以及镍与铅之间获得较弱的相关性。唯一的负相关是锶与铅之间，但回归模型中的解释百分比很低。结果表明，化学和物理相关元素钴、铜、锰和镍形成正相关。锶 - 镍和锰 - 铜的关系与人类松质骨报道的关系相似。
