[Morphological aspects of vascular changes in the gingival tissue in periodontosis].

The authors report the results from detailed morphological, histochemical and electron microscopic studies on the gingivae of patients without diseases other than periodontosis and of patients with periodontosis and underlying hypertension and atherosclerosis. In each group of patients, the authors established a relationship between the clinical particularities of the course of the periodontosis and the characteristics of the microcirculation in the periodontium. It was also evidenced that the changes in the gingival tissues observed in these groups of patients were due to fundamental differences in the impairment of the transcapillary metabolism which depends on the morphofunctional condition of the microcapillaries. These facts should be considered when adopting a treatment method.
