Tooth growth and mineralization follow an incremental pattern that creates daily growth lines (indicated by short white lines), as well as a neonatal line (NL) at birth. Growth starts at the enamel-dentine junction and both tissues continue to grow away from the junction (arrows) and towards the root. As the tooth mineralizes, barium and other elements are incorporated into the tissue depending on the amount circulating through the body and specific chemical properties. Variations in circulating barium lead to concentration patterns that reflect dietary transitions.
