THE studies which have been made on the occurrence of lead in normal teeth suggest that this element is consistently present in small amounts.'-7 The normal level for whole ashed teeth has been reported to be in the range of 20 to 70 ppm.3 4 Dentin appears to contain approximately 3 times more lead than enamel.3 There have been no studies on the. presence of lead in unerupted teeth or on uptake of lead by teeth. Therefore, it is not known to what extent lead found in teeth has been incorporated… Expand
The analysis and levels of lead in human teeth: a review.
TLDR
Since teeth provide an integrated historical record of a person's lead exposure they have some attractive features as biological indicators, compared with materials such as blood, but considerable care and attention to detail is necessary to obtain reliable data. Expand
Trace Elements in Ancient Indian Teeth
TLDR
To determine whether penetration of trace elements into the bulk of the tooth is a question of time, the concentrations of these elements were determined in surface and subsurface material of ancient teeth and the findings were correlated with comparable data available on contemporary teeth. Expand
Lead in teeth: the influence of the tooth type and the sample within a tooth on lead levels.
TLDR
Dentine appears to be the best material to use to estimate lead, particularly in relation to the integrated lead intake of a person. Expand
Exposure to metal ions and susceptibility to dental caries.

TLDR
Data from several epidemiologic studies and animal-based research support the concept that lead is a caries-promoting element, and Elevated blood levels are found most commonly in persons residing in inner cities, particularly among the poor. Expand
Discoloration of Teeth by Metallic Ions
TLDR
An investigation was undertaken to compare the possible staining properties of lead, tin, silver, mercury, copper, and iron when deposited in enamel and subsequently exposed to a sulfur-containing medium. Expand
Studies of the Composition of Teeth
TLDR
A study was made of the organic and inorganic composition of human enamel and dentin, utilizing the technics developed in previous studies of the composition of Syrian hamster's teeth. Expand
Human tooth enamel as a record of the comparative lead exposure of prehistoric and modern people.
There is a considerable body of evidence to support the contention that the atmospheric Pb burden is now considerably greater than it was in the remote past. However, as there are a diversity ofExpand
Detection of lead in human teeth by exposure to aqueous sulfide solutions.
TLDR
Most of the discoloration in both thin and intact tooth specimens was confined to the outermost layers of the tooth structure, and delta E was greatest for specimens exposed to the more concentrated Pb (NO3)2 solution. Expand
The epidemiology of dental caries in relation to environmental trace elements
TLDR
The influence of the geochemical environment on the epidemiology of human dental caries is reviewed and molybdenum has been associated with reduced caries prevalence whereas selenium and lead appear to have adverse effects. Expand
A plateau detected in lead accumulation in subsurface deciduous enamel from individuals exposed to lead may be useful to identify children and regions exposed to higher levels of lead.
TLDR
The threshold of 600 microg/g of lead in subsurface enamel was tentatively settled here after the plateau seen in exposed children, and enabled us to identify locations with more children exposed to a higher amount of lead. Expand

The Distribution of Fluoride in Human Enamel
TLDR
The purpose of the present study was to observe the distribution of fluoride in the enamel with the hope that a better understanding of its caries-reducing effect might be attained. Expand

Significance of Bone Trabeculae in the Treatment of Lead Poisoning : Lead Studies XVII.
TLDR
Further evidence is presented in favor of removing lead from the bones, which is stored in the bones for long periods of time and may be found in the excreta over a period of months and probably in small quantities for years. Expand
Normal absorption and excretion of lead.
TLDR
Various groups of healthy children and adults in the United States, with no occupational exposure, were shown to have lead in their tissues and in their excreta, chiefly because of regular occurrence of lead in the soil and hence in vegetation and animal products employed as food. Expand
Substances Capable of Decreasing the Acid Solubility of Tooth Enamel
TLDR
In the present work 147 substances, representing compounds of fifty-seven elements, were tested by one or both authors working independently in different laboratories without knowledge of the other's interest in the subject, and the solubilitydepressing effect of sodium fluoride, ammonium oxalate, lead nitrate, and silver nitrate was confirmed.

The Effect of Various Inorganic Salts on the Solubility of Calcium Phosphate, Tooth Enamel, and Whole Teeth in Lactic Acid
TLDR
In the case of lead nitrate and silver fluoride, increases instead of decreases in the weight of residue were obtained, no doubt as a result of precipitation of lead phosphate and silver phosphate, both of which have greater molecular weights than the calcium phosphate being dissolved. Expand

TLDR
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. Expand
