Enamel biopsies taken from schoolchildren in a community where exposure to lead was a health hazard were analyzed for lead and fluoride. The children with high enamel lead had significantly higher caries scores than the children with low enamel lead, in spite of the fact that the high lead group also was higher in enamel fluoride. There was no increase in enamel lead with age. The lead in saliva was only a fraction of that in blood. Infants with lead poisoning showed higher saliva lead than a…

Relation between lead in surface tooth enamel, blood, and saliva from children residing in the vicinity of a non-ferrous metal plant in Belgium.

Monitoring of two groups of schoolchildren exposed to lead (Pb) at a concentration that could cause health problems, found that surface enamel Pb concentrations correlated with blood-Pb concentration for the period starting with the pre-eruptive development of the incisors and corresponded partly to the exposure at the time of pre-ERUptive development and/or eruption.

[Lead level, enamel defects and dental caries in deciduous teeth].

No relationship was found between lead and dental caries in the industrial area of Piracicaba, thus emphasizing that more studies of such relationships are needed.

Salivary Lead Levels in Mixed Unstimulated Saliva of Children and its Correlation with Dental Caries

Lead poisoning, particularly causing a risk to children when they live in old houses in deprived urban areas can even affect the caries susceptibility of the child.

Study of lead and cadmium content of surface enamel of schoolchildren from an industrial area in Belgium.

A comparison of the concentrations of these heavy metals was made between children from a school close to a non-ferrous metal plant and children from the same age group from aSchool situated nearby the same plant but in a zone polluted to a lesser degree.

The association of tooth lead content with dental health factors.

Lead in teeth: the influence of the tooth type and the sample within a tooth on lead levels.

Association of dental enamel lead levels with risk factors for environmental exposure.

Surface dental enamel can be used as a marker of past environmental exposure to lead and lead concentrations detected are associated to well-known sources of lead contamination.



The Distribution of Lead in Human Enamel

The evidence of the importance of lead with regard to dental caries is negative and the solubility-reducing effect of lead needs further investigation because of the contradictory findings which have been reported on intact enamel.

Subclinical lead exposure in philadelphia schoolchildren. Identification by dentine lead analysis.

Abstract Dentine lead levels were measured from shed deciduous teeth of 761 Philadelphia schoolchildren with no prior history of lead poisoning and residing in two school districts, one considered

The Effect of Topical Applications of Fluorides on Dental Caries in Young Adults

Until clinical tests demonstrate that a treatment program which is effective in children is ineffective in adults, the conclusion that topical fluoride treatments do not prevent caries in adults is not warranted.

Lead Determination in Human Parotid Saliva

A microtechnique for quantitative determination of lead in human parotid saliva was developed by use of the technique of the Delves sampling cup and by atomic absorption and the resulting lead peaks are quantitated by comparison with standard lead peaks.

The effect of topically applied fluorides on dental caries experience; report of findings with two, four and six applications of sodium fluoride and of lead fluoride.

The results of the study indicate that four applications of a 2-percent solution of sodium fluoride, applied as described in the section on materials and methods, and preceded by dental prophylaxis, are the minimum number required to give maximum reduction in caries incidence.
