DIAGNOSTIC TECHNIQUE FOR EROSIOGENIC ACTIVITY OF ORAL FLUID IN PATIENTS SUFFERING FROM OESOPHAGEAL ORAL REFLUX ACCOMPANYING GASTROESOPHAGEAL REFLUX DISEASE Russian patent published in 2014 - IPC G01N33/48 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely dentistry, and concerns a diagnostic technique for the erosiogenic activity of the oral fluid in patients suffering from gastroesophageal oral reflux accompanying gastroesophageal reflux disease. The diagnostic technique for the erosiogenic activity of the oral fluid in the patients suffering from gastroesophageal oral reflux accompanying gastroesophageal reflux disease involves taking the oral fluid sample at 7 a.m., 2 p.m., 7 p.m., 11 p.m., and 3 a.m. next day and analysing the chemical property of the oral fluid sampled from the patients with or without dental erosions accompanying gastroesophageal reflux disease; the oral fluid is additionally analysed to measure chlorides and bicarbonates, variations of which are foremost observed at 11 p.m. and 3 a.m. next day; if the chloride amount measured is above a reference, while the bicarbonates are found to be less than that, the oral fluid is stated to be erosiogenic, while the chloride and bicarbonate amounts falling within the reference ranges allow considering the oral fluid to be non-erosiogenic with underlying gastroesophageal reflux disease.

EFFECT: technique provides the more accurate diagnosing of the erosiogenic activity of the oral fluid in the patients suffering from gastroesophageal reflux disease.
