[Evaluation of caries susceptibility in Northern Russian population by evaluation of medium-weight-molecular substances and oligopeptides]. / Otsenka kariesvospriimchivosti zubov u zhitelei Severa Rossii s ispol'zovaniem metoda registratsii srednemolekuliarnykh veshchestv i oligopeptidov.

Students of the Arkhangelsk State Medical Academy living in this area from the birth date and those from other climatic zones were examined. The metabolic status indices were defined content of low and middle molecular mass substances in blood and mixed saliva. There were certain features of biological fluidin spectrograms of caries susceptible persons. It was found that caries susceptibility of teeth depends on middle molecular substances pool in biological fluids.
