Fluorescence Spectroscopy Application in the Express-evaluation of the Gastrointestinal Microflora.

Possible application is studied for fluorescence spectroscopy in the express-evaluation of the gastrointestinal microflora. This diagnostic approach is feasible because of the difference in fluorescent spectra from different microorganisms, with anaerobic microorganisms exhibiting the most pronounced fluorescence. It was found that fluorescence strength raised with an increase in the bacteria Bacteroides and bifid bacteria, whereas it decreased with an increase in Escherichia coli.

Prospects for applying fluorescence spectroscopy to diagnose the hard tissues of a tooth.

This article deals with the autofluorescence spectra from the hard tissues of a tooth, both in norm and pathology. An investigation was made on 30 extracted human teeth. The measurements were made both for the intact hard tissues of a tooth, such as enamel, dentine, cementum, and root canal, and for the tissues pathologically affected by a caries (superficial, intermediate, and deep) and by a dental calculus.

[Problem in the diagnosis of anaerobic infections and dysbacteriosis in clinical dentistry].

The fluorescence technique was proposed for rapid diagnosis of anaerobic infection. It determines the microbiocenosis of a wound, the gastrointestinal tract, maxillofacial region, and other pathologically changed organs and tissues. The technique allows one to follow the time course of changes in the microflora and in the pathological process during the treatment and follow-up of a patient.
