Description
Abstract
Light and electron microscopy were used to
analyze the epithelial lining of odontogenic cysts excised
from edentulous regions of the jaws. Clinically, three
cases were identified as keratocysts, and 21 cases as
cysts other than keratocysts («non-keratocysts~)T. he
epithelium of the former was found to achieve
keratinization over most of the surface and to never
contain mucus secreting cells. The epithelium of the
latter appeared to be in part stratified squamous, with
cells loosely connected to each other, and in part
stratified columnar, with superficial cells connected to
each other by tight junctions and secreting mucus. The
results suggest that cysts arising from edentulous regions
of the jaws may be either keratocysts or cysts with
heterogeneous, non-keratinizing epithelium; the content
of keratocysts can be formed mainly by shedding of
comified epithelial layers, and that of non-keratocysts by
mucus secretion from columnar epithelium associated to
fluid filtration through non-keratinizing squamous
epithelium.
