[A morphological assessment of the efficacy of the deaggregation therapy of chronic catarrhal gingivitis].

Light optics, electron microscopy, morphometry were used to study the structural changes in the epithelial cells and endotheliocytes of gingival papillary capillaries of patients with chronic catarrhal gingivitis after papaverin therapy. The studies have revealed signs of disappearance of intercellular edema and a higher degree of cellular differentiation; signs of normalization of transcellular fluid transport were seen in the endotheliocytes, and aggregations of formed elements of the blood disappeared.
