Abstract:
As seen at semithin and ultrathin sections, there are marked changes in the cells and extracellular components of the microcirculatory bed in chronic periodontitis. These changes affect endotheliocytes, subendothelial zone, basal membrane and pericytes. In the capillary lumen there are erythrocytes and other corpuscles, platelets, in particular. A close contact of plasmocytes with components of the vascular wall confirms the leading role of vascular theory of chronic periodontitis pathogenesis.
