Morphological and morphometric studies of exfoliated oral squames from chronic inflammatory oral ulcers using light and scanning electron microscopy.

The morphological and morphometric features of exfoliated squames from the margins of chronic oral ulcers were studied by light and scanning electron microscopy. A variety of features consistent with a mixture of degenerative changes and regenerative activity were observed. None was sufficiently reliable to distinguish chronic inflammatory from malignant ulcers.
