Parodontal tissues were studied using semithin and ultrathin sections. Cell populations participating in parodontitis development consist of plasmocytes, fibroblasts, granulocytes, lymphocytes, endotheliocytes, mast cells and, to a lesser extent, epitheliocytes, thrombocytes, macrophages. The ultrastructural criterion of severe chronic parodontitis is the presence of pronounced changes in plasmocyte population with their transformation.
