摘要：
One-hundred and five impacted and erupted sound teeth were analysed for lead content by graphite furnace atomic absorption spectrophotometry. The results showed that lead accumulated before eruption, presumably soon after the onset of dentine formation. The accumulation in dentine was systemic, without any contribution from the oral environment. The amount of lead in dentine may denote the amount of absorption into the body and serve as a precise index to body burden as no absorption from the mouth can take place. In adults, impacted and erupted teeth can be used together in any research and the donor's age can be considered as the period of lead accumulation.
