Age dynamics of oral liquid chemical elements composition

By the method of x-ray spectral microanalysis studied the distribution of chemical elements (Na, Mg, Si, P, S, Cl, K, Ca, Zn) in amorphous and crystalline zones facies of the oral fluid of patients with sanitized by mouth in 5 age groups (25 people each): adolescents; the faces of young and middle age; the elderly; elderly; long-livers. The content of calcium associated with organic components, in facia oral fluid of centenarians was 4 times higher compared with its content in adolescents, in 2 times above, than at patients of young and middle age, 1.5 times higher than in the elderly, and 1.2 times higher in comparison with its content in patients senile age. Such age-related increase in the calcium concentration in the oral fluid can be explained safe level of its production of calcium salivary glands, increasing reduced intake of calcium from the oral fluid for enamel remineralization in connection with the gradual loss of teeth and destructive processes in periodontal tissues in patients of older age groups.
