Lead storage in teeth was evaluated by examining the lead concentration in deciduous teeth of 32 children whose habits of pica and state of lead exposure had been studied when they were between 1 and 3 years of age. Concentratios of lead in their teeth depended on the reported amount of paint or plaster intake and the duration of exposure. The mean dental concentration of lead in exposed children was significantly higher than the mean value in 36 controls, who presumably did not have undue exposure to lead. A difference in dental lead concentration related to living area was noted. The significant difference in lead content of teeth between the two groups, even though the concentrations of lead in blood at 8 years of age were similar, emphasizes the importance of dental lead measurments for retrospective studies of lead exposure.
通过检测32名儿童乳牙中的铅浓度来评估牙齿中的铅储存情况，这些儿童在1至3岁时曾对其异食癖习惯和铅暴露状况进行过研究。他们牙齿中的铅浓度取决于所报告的油漆或石膏摄入量以及暴露持续时间。暴露儿童牙齿中的铅平均浓度显著高于36名对照组儿童的平均值，后者推测没有过度接触铅。注意到牙齿铅浓度与居住地区有关。两组儿童牙齿铅含量存在显著差异，尽管8岁时血液中的铅浓度相似，这强调了牙齿铅测量对于铅暴露回顾性研究的重要性。
