ABSTRACT
The electrokinetic activity of buccal epithelial cells drops in patients with lichen planus. The most pronounced changes develop in patients with severe forms of the disease (exudative hyperemic and erosive ulcerative). The functional activity of the epithelium does not depend on sex or presence of metal dentures; the effect of the disease duration is negligible, while the underlying somatic disease is significant. The electrokinetic activity of epithelial cells is sharply reduced in cardiovascular patients with lichen planus of the buccal mucosa. Increase of electrokinetic activity of epitheliocytes after local drug therapy for lichen planus clinically manifests by epithelialization of erosions, which recommends this test for predicting the course and outcome of lichen planus.
