摘要：
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.
