Stress -induced disturbances of the structure of periodont tissue in experiment on animals

[Experimental medicine]

The aim of the study was to assess the condition of periodontal tissues of experimental animals under conditions of chronic stress caused by a device that forms nonphysiological occlusion of jaws in rats. The results of electron microscopic, X-ray and pathomorphological evaluation of periodontal tissues are presented in the modeling of chronic stress, indicating the dynamic development of destructive processes in the depth of the jawbone. The relationship of weight gain in experimental animals, disproportionate to the nature of nutrition, and deep atrophy of the alveolar process starting from the vertices of the interalveolar septa is shown.
