Abstract: | We examined the differences between the concentrations of chemical elements in caries-changed primary teeth and permanent
ones with a division into the root and the crown. The study comprised 27 children aged from 4 to 11 yr and 36 adults aged
from 36 to 71 yr. We examined the elements with the total reflection X-ray fluorescence method. The lowest concentrations
of calcium, manganese, strontium, lead, and copper were in the roots of primary teeth compared to the roots of permanent ones.
The calcium, nickel, zinc, lead, and copper concentrations were significantly higher in the roots of primary teeth than in
the roots of permanent teeth. However, the zinc concentration was higher both in the root and crown of primary teeth than
in permanent teeth. On the basis of our investigations, we can conclude that the content of some elements (manganese, copper,
strontium, and lead) is higher in caries permanent teeth than in primary ones. The nickel and zinc concentrations are higher
in the teeth of the children than the adults. However, the content of other elements (calcium, chromium, iron) is similar
in both kinds of teeth. |
