Abstract
The effect of age on Ca, Cl, K, Mg, Mn, Na, P, and Sr contents in intact roots of permanent teeth of 38 apparently healthy women aged 15–55 years was investigated by neutron activation analysis. It was found that mass fractions of Ca, Cl, K, Mg, and P are at a maximum in the age range 25–35 years and above 35 years there is a monotonic decrease. A statistically significant age-dependent decrease was shown only for Mg and P. The Sr content significantly increases with age. The mass fractions of Mn and Na remain stable for the ages 15–55 years.
