Autoradiographic analysis of epithelial proliferation in chronic gingivitis

Abstract

Proliferative processes in the gingival mucosa are studied by autoradiogmphy in 55 patients with chronic gingivitis. It is found that the number of DNA-producing epithelial cells does not change. Increased label intensity in chronic catarrhal and hypertrophic gingivitis in comparison with the control testifies to a sufficient compensatory reaction. Regenerative processes are suppressed in chronic atrophic gingivitis. The number of pathological mitoses increases with the development of pathomorphological changes in all studied types of ghlgivitis.
