Abstract
The amount of lead in deciduous teeth has been used extensively as a marker for infant lead exposure and body burden. Elevated tooth lead levels have been seen in children who had lead poisoning. Also, on a population wide basis tooth lead levels appear to vary according to housing status and presumably lead exposure. This exposure index has been applied using varying techniques in Denmark, and the United Kingdom. Because of the neurotoxicity of lead, the tooth lead levels of retarded and normal children have been compared. Most recently, in research of lead and child development, tooth lead levels have been used as markers of past lead exposure. Despite the widespread use of tooth lead values, very little is known about the exact time course of lead deposition in tooth from blood. This report compares blood lead levels at different ages to tooth lead levels in a group of Boston children.
