Analysis of the results obtained by national research groups with the Russian state cancer program for the screening of diseases of the oral mucosa and the vermillion border.

AIMS AND OBJECTIVES: The purpose of the article is to analyze the results obtained by the national research groups with the Russian State Cancer Program for the screening of diseases of the oral mucosa and the vermillion border. This article analyzes the results obtained by national research groups in the implementation of the Russian State Cancer Program. BACKGROUND: Based on the Department of Therapeutic Dentistry of A.I. Yevdokimov Moscow State University of Medicine and Dentistry, national research groups were created to implement the state program draft for the screening of oncological and precancerous diseases of the oral mucosa and the vermillion border - a grant of the "A" format to support applied research on a competitive basis in the form of subsidies of the federal target program. MATERIALS AND METHODS: From 2015 to the first half of 2019, the national clinical groups studied the epidemiology (prevalence rate and structure) of oncological and precancerous diseases of the oral mucosa and the vermillion border in 486,059 persons aged 18-92 years living in Tula, the Tula region, Moscow and Noyabrsk as a result of active pathology detection during targeted examination of the population (screening) and appealability in the preclinical period, early, timely and late detection. RESULTS: the results of the research confirm low cancer alertness of practicing dentists. An individual patient registration card has been developed to systematize data and create a diagnostic register for the screening of cancer and precancerous diseases of the oral mucosa and the vermillion border. CONCLUSION: A project has been developed to implement the Russian State Cancer Program for oncological and precancerous diseases of the oral mucosa among the population of the Russian Federation.

Periotestometry and tissue hydration. How are these indicators related?

The mobility of teeth in terms of periotestometry and hydration of periodontal tissues in terms of bioimpedance spectrometry were studied in healthy volunteers without dental and concomitant somatic diseases. It was found that teeth of these subjects have both low and pathological mobility. It was also revealed as increased hydration (edema), indicating the presence of inflammation, and reduced hydration, indicating atrophic processes in periodontal tissues. A comparison of the data of periotestometry and bioimpedance spectrometry showed that the indicators of mobility of the teeth and hydration of the periodontal tissues reflect different characteristics of the functional state of dentoalveolar system, and can be used as complementary in the diagnostic studies.
