EARLY DIAGNOSTIC TECHNIQUE FOR ORAL DISEASES IN ADOLESCENTS BY MICROELEMENT COMPOSITION AND LACTIC ACID BACILLI CONCENTRATION IN NON-STIMULATED ORAL FLUID Russian patent published in 2012 - IPC G01N33/84 G01N33/569 

FIELD: medicine.

SUBSTANCE: non-stimulated oral fluid is collected on an empty stomach and analysed for the concentrations of sodium, potassium, calcium, phosphorous and lactic acid bacilli. The relations Ca/P and Na/K are calculated. The values Ca/P 0.63, Na/K 1.2 and lactic acid bacilli count 10³-10⁴ enables diagnosing a risk of caries and inflammatory diseases of periodontium tissues; the values Ca/P 1.3, Na/K 0.9 and lactic acid bacilli count 10⁵-10⁶ enables diagnosing a risk of developing caries and no risk of inflammatory diseases of periodontium tissues; while the values Ca/P 1.1, Na/K 1.2 and lactic acid bacilli count 10⁵-10⁶ provides diagnosing a risk of caries and inflammatory diseases of periodontium tissues.

EFFECT: technique enables accurate diagnosis of a risk of developing caries and inflammatory diseases of periodontium tissues in screening programs.
