“…In teeth, Pb levels found here were comparable with those in some other countries, e.g., Turkey (former, 3.42 μg g −1 [53]; recent, 1.30–1.77 μg g −1 [54]), and non-polluted regions of Brasilia (1.3 μg g −1 ) [55], while enhanced Pb and Cd teeth levels were observed in children from heavy industrial area of southern Poland [56]. …”

The population of about 300 6-year-old preschool children was studied for lead (Pb) and cadmium (Cd) in deciduous teeth, scalp hair, and capillary blood. Zinc (Zn) content in hair was also measured due to its possible interferences with the elements studied. The Pb and Cd contents were measured by graphite furnace atomic absorption spectrometry with Zeeman background correction, and Zn, by flame method. Metal levels found were comparable to those in European countries. Positive correlations between Pb and Cd in the same and different tissues were widespread (r = 0.23–0.68). A positive correlation was found between Pb in teeth and blood (r = 0.65, p < 0.001). Pb blood threshold 100 μg L−1 referred to 2.6 μg g−1 Pb in teeth. Predictability of this Pb teeth limit was 14% vs. 5% for Pb blood. Strong negative correlation was found between hair Pb and Zn (r = −0.68, p < 0.001). Enhanced Cd and Zn levels in hair were associated with the household drinking water hardness. The associations with some other environmental and behavioral factors were also presented and discussed. The results proved the advantage of analysis of primary teeth for Pb exposure screening of preschool children.

“…Exposure to this metal can be evaluated by measuring lead in blood, teeth, hair, and bone which are then used to estimate body lead burden 1 . Most studies looking at lead exposure among children have used blood‐lead (BPb) levels as a marker of exposure 3,5 . Lead in the blood has a short half‐life of 30 days and reflects recent exposure and, therefore, is of limited value in predicting neurotoxicity 3 .…”

International Journal of Paediatric Dentistry 2010; 20: 186–192 Background. Lead toxicity particularly affects children because of their increased capacity for absorption and retention. Blood‐lead (BPb) levels reflect recent exposure and are of limited value in predicting neurotoxicity, whereas in teeth, lead accumulates over a long period of time and provides an integrated record of lead exposure from intrauterine life until the teeth are shed. Aim. The present study aimed to relate tooth‐lead (TPb) and BPb levels in children residing near a zinc–lead smelter in India, and to evaluate the effectiveness of primary teeth as bioindicators of life‐long lead exposure. Design. The lead levels in primary teeth and blood of 100 children aged between 5 and 13 years, living in the proximity of a zinc–lead smelter were measured by atomic absorption spectrophotometry. The mean levels were tabulated based on village, age, sex and tooth type, and analysed statistically. Results. The mean BPb level was significantly influenced by proximity to the lead source, but not by age or sex. There was no consistent pattern of correlation between BPb and TPb levels. Conclusion. Primary teeth showed significantly high lead levels compared to blood; they reflect cumulative exposure to lead and prove to be better indicators of body lead burden.

“…Omar et al, 25 found a significant difference and attributed this to the greater industrialization of many parts in Egypt; more exhaust fumes from cars, industrial emissions and use of canned food and possible water contamination. Karakaya et al, 26 examined the content of lead of 7-12 age children deciduous teeth collected in suburban and urban areas of Ankara to be the capital of Turkey. Karahalil et al, 27 examined the content of lead of deciduous teeth collected from 4-15 age children who have been living in areas of Ankara and Balıkesir.…”

“…Thus, differences in the lead level were found between urban or industrial areas and rural zones or between different areas of the same city. [26][27][28] Experimental evidence shows a doseresponse relationship between blood lead and dentin lead. Also, increasing lead levels have been documented in permanent teeth with increasing age.…”

Chemical and radioactive gases are released to the environment from Turkey's largest thermal power plant located in Afsin-Elbistan region. Such gases remain suspended in the air, form a layer on the soil surface, seep into groundwater, may be carried to human body through foods and inhalation, and may accumulate in bones and teeth. In this study, accumulations of toxic elements emitted from the thermoelectric power plant in dental, soil, water and plant samples were analyzed. It was statistically determined that there was no significant difference (p>0.05) between the values obtained in consequence of the variance analysis made with intent to evaluate the samples taken from the vicinity of the power plant examined within the scope of the research, and from the city of Yalova examined for control purposes.
