The effect of a low-intensity magnetic field combined with polarized light on the microvasculature links in periodontal tissues during orthopaedic treatment by fixed dentures in patients with partial secondary adentia and periodontal diseases were determined using an experiment on laboratory animals. The aim of the research was to study the character of morphological changes in the tissues of pathologically changed periodontium after exposure to magneto phototherapy in animal testing. Objects and methods. The experiment was made on selected 107 random-bred rats. The animals were divided into three groups: control group 1, control group 2, and the experimental group. Results and discussion. A dynamic analysis of morphological changes in the tissues of pathologically changed periodontium in three groups of animals demonstrated that, as compared to other animals, the rats from the experimental groups, following experimental magneto phototherapy, had early elimination of inflammation. Conclusion. Early elimination of inflammation (1 hour after termination of the impact) in all gum components and perifocal structures due to vaporization of inflammatory cells, activation of vessels (plethora and a noticeable increase in number) was found after the exposure to magneto phototherapy, while regeneration and complete epithelialization of the gingival pocket completed 2 days after termination of magneto phototherapy.
