AUTOFLUORESCENCE METHOD FOR DIAGNOSING PERIODONTIUM TISSUE DISEASES Russian patent published in 2006 - IPC G01N33/52 

FIELD: medicine.

SUBSTANCE: method involves measuring autofluorescence in red bandwidth of spectrum under study I_b and periodontium region autofluorescence intensity of minimum autofluorescence intensity I_n. The region under study is treated with Schiller-Pisarev solution and autofluorescence intensity I_a is measured for the second time. Coefficients K₁= I_a/I_b and K₁= I_n/I_a are calculated. If K₁ coefficient belongs to bandwidth from 0.700 to 1.000 and K₂ coefficient belongs to bandwidth from 0.005 to 0.350, deep micro flora location is to be diagnosed. If K₁ coefficient belongs to bandwidth from 0.350 to 0.700 and K₂ coefficient belongs to bandwidth from 0.350 to 0.700, deep and superficial micro flora location is to be diagnosed.

EFFECT: high accuracy of study results.
