proliferation, epithelial,
n a characteristic finding in inflammatory lesions affecting the gingival tissues; consists of hyperplasia of the pocket epithelium, with extension and elongation of epithelial rete pegs into the submucosa. Accompanying the hyperplastic changes in the crevicular epithelium, it is noticed that the epithelial attachment proliferates onto and alongside the cementum. Also, the multiplication of epithelial cells resulting either in increased thickness or new epithelial covering of a wound or an ulcer. See also pocket, periodontal.
