Comparative study of B content and δ B in the enamel of isolated teeth from brothers in the same family.

Rationale: The quantity of boron (B) and its isotopic ratios in tooth can provide information on dietary habits and oral health of individuals. These metrics are gradually being used in stomatology, environmental science and geochemistry.

Methods: This study measured the B concentration and δ B in the enamel of isolated teeth from brothers in the same family living in high-B-exposure areas at different times using inductively coupled plasma mass spectrometry (ICP-MS) and multicollector ICP-MS.
