“…33 In some children we observed higher lead levels in enamel than dentine, which could be due to our inadvertent sampling of 'lead enriched' surface enamel; in vivo acid biopsies of the enamel surface reveal that the first few microns of enamel have anomalously high lead values. 26,27 The overall mean dentine lead level in this study in 2005 (0.26±0.16µg/g) was considerably lower than whole tooth lead levels from a UK study carried out more than twenty years earlier.…”

“…Tooth lead has been considered a potential biomarker for measuring long-term exposure to lead (e.g., years) because lead that accumulates in tooth dentin and enamel appears to be retained until the tooth is shed or extracted (Ericson 2001;Gomes et al 2004;Omar et al 2001;Rabinowitz et al 1989;Steenhout and Pourtois 1987). Formation of enamel and coronal dentin of deciduous teeth is complete prior to the time children begin to crawl; however, lead in shed deciduous teeth is not uniformly distributed.…”

“…Nå kan man, ved hjelp av mer avanserte teknikker, ta serier av prøver på slipesnitt av tannen på tvers av vekstlinjene [29,32]. Etter registrering av neonatallinjen (Figur 2), kan melketannen analyseres for sporelementinnhold i tannvev dannet før og etter fødselen, for å kartlegge variasjoner i elementinnholdet [6,33]. Denne metoden er også mindre destruktiv idet bare en mindre del av tannen brukes i analysen.…”

“…Enkelte vev og vaesker i kroppen kan brukes til å måle kroppens opptak av elementer og forbindelser fra miljøet, såkalte biomarkører for eksponering [4]. Melketenner har vaert brukt som biomarkører i en rekke studier og kan gi viktig informasjon om barnets miljø på fosterstadiet og i tidlig barndom [5][6][7]. Sporstoffer fra miljø og ernaering bygges inn i tannvevet etter hvert som tennene dannes.…”
