“…The recent studies in adults showed that high PBT levels might be related with diabetes and hypertension [51]. It was also found that high blood lead (PBB) and PBH was associated with breast cancer [52].…”

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.

“…These methods are commonly employed because the samples are easily collected. Tooth has also been used in one study [34]. The turnout rate of trace metals in the blood and urine is rapid; whereas the hair, fingernail and tooth accumulate these elements over a long period.…”

SummaryCopper and zinc are essential trace biometals that regulate cardiovascular homeostasis, and dysregulation of these metals has been linked to vascular diseases, including hypertension. In this article, we review recent human population studies concerning this topic, focusing on: 1) the relationship between blood pressure and levels of zinc and copper; 2) correlations between trace metals, the renin-angiotensin system, obesity, and hypertension; 3) the relationship between environmental metal pollution and the development of hypertension; and 4) methods commonly employed to assay zinc and copper in human specimens. Moreover, based on the findings of these studies, we suggest the following topics as the basis for future investigations: 1) the potential role of environmental metal pollution as a causal factor for hypertension; 2) metal profiles within specific pathogenic subsets of patients with hypertension; 3) standardizing the experimental design so that the results between different studies are more comparable; and 4) the requirement for animal experiments as complementary approaches to address mechanistic insight that cannot be studied in human populations.

“…Also, the effect of treatment time and the type of appliance used on the amount of released metal ions as a consequence of corrosion has not been evaluated. This is related with difficulties associated with the use of invasive vs. noninvasive biomarkers [13, 14]. It seems that multidisciplinary approach towards the problem of the assessment of exposure of human organism to trace elements may reveal different aspects associated with the application of metallic materials in dentistry [15–18].…”

In this paper, we report the results of an in vitro experiment on the release of metal ions from orthodontic appliances composed of alloys containing iron, chromium, nickel, silicon, and molybdenum into artificial saliva. The concentrations of magnesium, aluminum, silicon, phosphorus, sulfur, potassium, calcium, titanium, vanadium, manganese, iron, cobalt, copper, zinc, nickel, and chromium were significantly higher in artificial saliva in which metal brackets, bands, and wires used in orthodontics were incubated. In relation to the maximum acceptable concentrations of metal ions in drinking water and to recommended daily doses, two elements of concern were nickel (573 vs. 15 μg/l in the controls) and chromium (101 vs. 8 μg/l in the controls). Three ion release coefficients were defined: α, a dimensionless multiplication factor; β, the difference in concentrations (in micrograms per liter); and γ, the ion release coefficient (in percent). The elevated levels of metals in saliva are thought to occur by corrosion of the chemical elements in the alloys or welding materials. The concentrations of some groups of dissolved elements appear to be interrelated.
