Age influence on periodontal tissues: a histological study.

Abstract

Oral mucosa becomes thinner, smooth and looses stippling aspect with aging. From histological standpoint appears: narrowing and alteration of gingival epithelium, modification of epithelial-connective interface and decreasing of keratinization. However, it cannot be detected significant histological alterations in size, shape or arrangement of epithelial cells that could be endorsed to aging process. Histological studies indicate: decreasing of keratinization, regressive changes in epithelium and fibrosis in underlying connective tissue. Parakeratosis is frequent with aging because of microtraumas, in many cases is expression of permanent inflammation.
