BIVALENT CATIONS IN ORAL PATHOLOGY.

Bivalent cations have multiple actions in the oro-maxillary region. In patients with oro-maxillary area suppurations, our data revealed significant increase in the salivary magnesium concentration and a decrease in the serum zinc concentration. In maxillary sinusitis, there are no changes in the calcium and magnesium concentrations, whereas the plasmatic zinc level is decreased. Zn, Cu, Ca, Mg also play important roles in the synthesis of dental enamel, and their misbalances are involved in the pathogeny of tooth decay and other maxillary diseases [ABSTRACT FROM AUTHOR]
