Aim, Material and Methods. The aim of the study was to study the nature of the structural and functional features of the epithelium of the oral mucosa and the tongue of laboratory animals as a result of exposure to broadband red light. Results and Discussion. As a result of morphological and electron microscopic analysis of the structural changes of the oral mucosa and tongue of 10 rabbits and 120 Wistar rats after exposure to broad-band red light, the absence of severe, irreversible changes in the epithelium, submucous layer and its components, mild and reversible hemodynamic and hemoreological disorders, manifested mainly by the full blood vessels of the microcirculatory bed, in three cases was seen the sludge and stasis of blood in the capillaries, as well as small ones diapedetic hemorrhages with localization in the subepithelial zone. Conclusions. The data obtained allow recommending the method of photoneuromodulation for wider use in practice when treating patients with the burning mouth syndrome.
