Atherosclerosis precursors in Finnish children and adolescents. XIV. Zinc and copper concentrations in deciduous teeth

Abstract

land). Atherosclerosis Precursors in Finnish children and adolescents. XIV. Zinc and copper Concentrations in deciduous teeth. Acta Paediatr Scand Suppl. 318: 213, 1985. Zinc and copper concentrations were analysed from cariesfree deciduous teeth of 125 Finnish children, 6-7-and 9-10-year-olds, from three cities. Enamel and dentine were separated and prepared into pills which were analysed individually with the proton induced x-ray emission spectrometry (PIXE) method. The total mean ( f SD) zinc concentrations for enamel and dentine were 143 f 31 and 133 f 36 ppm, respectively, and are in agreement with the values reported recently. The median copper concentration for enamel was 0.54 ppm with a range from 0.0 to 4.29 and for dentine 0.27 ppm with a range from 0.0 to 3.60 being among the lowest reported. The low copper values are interesting as to the possible association with the development of atherosclerosis. Geographical differences were noted between the zinc concentrations of the three cities, the children of Helsinki having significantly higher zinc values than the children of Kuopio and Oulu. No linear correlation was found between zinc and copper concentrations at the individual level. Key words: copper in teeth, deciduous teeth, trace elements, zinc in teeth.

Levels of lead, cadmium, copper, iron, and zinc in deciduous teeth of children living in Irbid, Jordan by ICP-OES: some factors affecting their concentrations

“…The median concentration of Pb in teeth of children living in Brazil (Gomes et al 2004) was found to be 169 μg/g from the industrial area and 118 μg/g from the children living far from the industry. The average concentrations of Zn in Finnish children were 143 and 133 ppm for enamel and dentine, respectively, and the median Cu concentrations for enamel and dentine were 0.54 and 0.27 ppm, respectively (Haavikko et al 2008). The average concentrations of Pb, Cu, Fe, and Zn in human teeth from Poland were 17.1, 4.4, 46.6, and 802.2 μg/g, respectively (Baranowska et al 2004).…”

Tooth Element Levels Indicating Exposure Profiles in Diabetic and Hypertensive Subjects from Mysore, India

“…The levels of elements that are lower in the teeth of control subjects from Mysore than that of other investigations [11,[21][22][23] are indicative of low levels of environmental exposure to heavy metals. Likewise, low levels of Pb-T were reported in the 9-year-old children from two (Helsinki and Kuopio) Finnish towns [6].…”

“…In the case of nutritional elements, low Cu-T levels detected in the hypertensive subjects of Mysore and Finnish children with atherosclerosis [11] may be attributed to nutritional implication. It is, therefore, viewed that human teeth may indicate low status of essential trace elements.…”

“…Whereas, Brown et al [24] demonstrated that Uganda children with endomyocardial fibrosis had greater cerium levels in their primary teeth than the controls. In addition, enhanced levels of Cd and Pb were, respectively, discerned in the deciduous teeth of Finnish children with atherosclerosis [11] and children with chronic renal failure [12]. In all such cases, the excessive levels of nonessential trace elements (Pb, Cd, and Ce) may be ascribed to origin of the health disorders.…”

“…In support, few investigations have elucidated that there exists correlation between elevated Pb-T levels and development of atherosclerosis in Finnish children [11] and chronic renal failure in children [12]. Whereas, other studies have revealed no relationship between Pb-T levels and children's neurobehavioral measures [13] and preschool children with enamel defect from Penacicaba, state of Sau Paulo, Brazil [14].…”
