FEATURES OFT THE PERIODONTAL TISSUES ULTRASTRUCTURE UNDER CHRONIC PSYCHOEMOTIONAL STRESS

Abstract

With the help of electron microscopic and morphometric methods, the features of changes in the ultrastructure of periodontal tissues in persons with psychoemotional stresses were studied.It was shown that chronic psychoemotional stress is accompanied in the gum tissue by the development of endothelial and mitochondrial dysfunction with signs of edema and destruction of the capillary endothelium and a violation of the ultrastructure of about 50 % of the mitochondria in the cells.Structural changes were also observed in bone tissue. They testified about the development of destructive processes with the violation of intercellular signaling system and signs of necrotic cells. Such changes in the gum and bone tissues can promote the development of periodontitis in the case of chronic psychoemotional stress and lead to tooth loss.
