The aim of the study was to determine the content of: Pb, Cd, Cr, Ni, Fe, Mn, Cu, Zn in the impacted third molars and a fragment of covering bone. Patients were divided according to following criteria: place of residence, age, gender, anatomical location of the removed tooth. Content of Cd, Pb, and Mn in the samples increases with age of the patient. The content of Cd and Pb in the tooth and bone was higher in patients living in Wroclaw. Residents of the Wroclaw had higher Cu content in the teeth, while they had a lower content in the jawbone. In contrast to Cd and Pb, an average of 68% higher concentration of Zn in the jawbone than in the tooth was noted. The content of Cr in tooth was lower by 33% than in the mandible bone and, similarly to the content of Ni, it decreased with age. In women, the Fe content in bone of the jaw was higher than in the removed tooth. The presence of Pb and Cd aggregates is confirmed in all hard tissues of the tooth and bone, in contrast to bioelements which show a stronger tendency to aggregate, essentially within the dentine.
本研究的目的是测定阻生第三磨牙及覆盖骨碎片中铅（Pb）、镉（Cd）、铬（Cr）、镍（Ni）、铁（Fe）、锰（Mn）、铜（Cu）、锌（Zn）的含量。患者根据以下标准进行分组：居住地、年龄、性别、拔除牙齿的解剖位置。样本中镉、铅和锰的含量随患者年龄增加而升高。弗罗茨瓦夫的患者牙齿和骨骼中的镉和铅含量更高。弗罗茨瓦夫居民牙齿中的铜含量较高，而颌骨中的铜含量较低。与镉和铅相反，颌骨中锌的平均浓度比牙齿中高68%。牙齿中铬的含量比下颌骨低33%，与镍的含量相似，它随年龄增长而降低。在女性中，颌骨中的铁含量高于拔除的牙齿。与生物元素相比，牙齿和骨骼的所有硬组织中均证实存在铅和镉聚集体，生物元素更倾向于在牙本质内聚集。
