FIELD: medicine. SUBSTANCE: method involves measuring DC value flowing via metal structures available in oral cavity. Electric current intensity is measured in direct and reversed connection polarity with respect to power supply source of galvanic system under study. System impedance is calculated as circuit resistance mean value in two measurements. The value is interpreted in terms of galvanic processes intensity in oral cavity. The oral cavity area under study is preliminarily dried. EFFECT: high accuracy and reliability of measurements. 3 dwg
