Abstract

Amalgam has been used as a filling material for over 150 years. Mercury, copper, and zinc are present in restoration. The aim of this study was to compare mercury, copper, and zinc concentrations in extracted human teeth with amalgam restorations and teeth without restorations. Thirty-two teeth, 15 restored with dental amalgam and 17 without restorations, were chemically analyzed in an Optima 3300 DV (Perkin Elmer) plasma emission spectrometer. Mercury, copper, and zinc were found in human teeth regardless of the presence of amalgam restorations. The highest mercury concentrations were found in the coronary portions of the teeth with amalgam restorations. Copper concentrations were very high. Zinc concentrations in the teeth without restoration were lower than those seen in the coronary portion of the teeth with restorations.

摘要

汞合金作为一种填充材料已使用了150多年。修复体中含有汞、铜和锌。本研究的目的是比较有汞合金修复体的拔除人类牙齿与无修复体牙齿中的汞、铜和锌浓度。在Optima 3300 DV（珀金埃尔默公司）等离子体发射光谱仪中对32颗牙齿进行了化学分析，其中15颗用牙科汞合金修复，17颗无修复体。无论是否存在汞合金修复体，人类牙齿中均发现有汞、铜和锌。在有汞合金修复体的牙齿冠部发现汞浓度最高。铜浓度非常高。无修复体牙齿中的锌浓度低于有修复体牙齿冠部的锌浓度。
