METHOD OF DIAGNOSIS OF GYNGIVITIS IN CHILDREN Russian patent published in 2017 - IPC G01N33/48 

FIELD: medicine.

SUBSTANCE: method involves preliminary preparation of the patient's saliva sample, then carry out a study sample of saliva by IR - absorption spectra in spectroscopy 1200-1000 cm^-1. On the obtained IR spectrum is determined by the height of the peaks of the absorption bands with peaks in 1165, 1150, 1140, 1070, 1040 cm^-1. And then calculating the ratio of the peak height of the peak at 1165 cm-1 peak to peak height of the 1070 cm^-1, height of the peak with a maximum at 1165 cm^-1 to the peak height of the peak 1150 cm^-1, height of the peak with a maximum at 1165 cm^-1 to the height of the peak from 1140 cm^-1 maximum, height of the peak with a maximum at 1040 cm-¹ peak to peak height of the 1070 cm^-1 and value of the ratio 1165/1070, equal to 0.17±0.02, with the value of the ratio 1165/1150, equal to 0.28±0.06, with the value of the ratio 1165/1140, equal to 0.41±0.01, and the value of the relationship 1040/1070, equal to 0.63±0.03 diagnose gingivitis.

EFFECT: method is simple and accurate, requires the implementation of expensive and time consuming and can be recommended as a screening diagnosis of a large population of patients due to its simplicity, accuracy, and efficiency and the use of standard equipment - IR spectrophotometer.
