Prophylaxis and screening diagnostic methods for precancerous diseases of the oral mucosa and early forms of cancer

Precancerous diseases of the oral mucosa and those of the vermillion are common pathology; in 62.7-96.4% of cases they precede the onset of cancer. Although the mucous membrane of the mouth and vermillion are visible during observation, malignant neoplasms in a large percentage of cases (more than 60%) are diagnosed by dentists in later stages. In this sense, doctors of dental medicine should pay increased attention in terms of oncological pathology, including by using additional diagnostic methods.

Currently, in order to actively detect precancerous diseases and early stages of malignant neoplasms of oral cavity and vermilion, in addition to observation and palpation of the regional lymph nodes, un innovative method of screening diagnosis – fluorescence (autofluorescence) stomatoscopy is used. As a result of autofluorescence stomatoscopy in the focus of precancerous and cancerous diseases, the intensity of luminescence is significantly reduced and they are visualized as focal nonhomogenic darkening (“dark spot” effect).

Luminescent (autofluorescence) stomatoscopy is a non-invasive, contactless method for visualizing precancerous diseases and early stages of malignant tumors of the oral cavity and vermillion, which allows increasing the efficiency of the diagnosis by using an APS LED device.

Autofluorescence stomatoscopy of the oral mucosa was performed in 25 503 patients. Precancerous diseases were detected in 110 patients and 28 patients were diagnosed with cancer of the oral mucosa and vermillion. In 2421 patients who did not have complaints, inflammatory diseases of the oral mucosa were identified.

The obtained results testify the effectiveness of using autofluorescence diagnostics with the LED device APS in the conditions of dental treatment in order to keep oncological vigilance.

Key words: diagnosis, precancerous diseases of oral mucosa; fluorescent stomatoscopy.
