Dentine lead

An analysis of eight cross-sectional and/or prospective studies which reported tooth lead and PbB levels of the same children found considerable consistency among the studies (Rabinowitz 1995). The mean tooth lead levels ranged from under 3 to over 12 pg/g. In a study of 63 subjects, dentin lead was found to be predictive of concentrations of lead in the tibia, patella, and mean bone lead 13 years after tooth lead assessment in half of them (Kim et al. 1996b). The authors estimated that a 10 pg/g increase in dentin lead levels in childhood was predictive of a 1 pg/g increase in tibia lead levels, a 5 pg/g in patella lead levels and a 3 pg/g increase in mean bone lead among the young adults.

Current opinion comes from the intellectual functioning observed in case reports or large groups of children with varying levels of exposure measured with blood or dentine lead levels. Several reports link mental retardation or autism to higher blood lead levels, but few can determine whether higher lead levels cause the impairment or result from increased pica often observed in mentally impaired children.
