Abstract

The concentrations of Ca, Mg, Na, K, Cl, Zn, Sr, Mn, Ba, Br, and Au were determined in individual samples of dental calculus collected from patients resident in the Manchester area. The method used was instrumental neutron activation analysis (INAA), combined with gamma-spectrometry. The highest and lowest values of Sr were found in calculus from patients of Asian origin. No differences were found in the elements studied with regard to sex or age. Individual variations were highest in Au and lowest in Ca.
