Abstract
Deciduous teeth were analyzed by atomic absorption spectroscopy for lead content to ascertain the extent of lead exposure in certain areas in Tennessee. The data were analyzed to clarify the relationships between tooth lead content and race, sex, age, tooth type, economic status, and place of residence. Results indicated that blacks had slightly higher lead concentrations than whites; however, the age and sex of the person or the type of tooth analyzed had little effect upon the lead content. The major factors were shown to be economic status and, indirectly, place of residence.
