Abstract
ABSTRACT
The Keratocystic Odontogenic Tumor is a developmental cyst derived from the
enamel organ or from the dental lamina. It is a benign, multicystic, intraosseous
tumor of odontogenic origin, with a characteristic lining of parakeratinized
stratified squamous epithelium and has a potential for aggressive, infiltrative
behavior and recurrence. Keratocystic Odontogenic Tumors have a predilection for
males and occurs mainly in the second and third decade of life, most commonly in
the mandible, mostly in the posterior body, the angle and the ascending ramus.
It extends in the intramedullary space making it difficult to diagnose at an early
stage. It is regarded as a distinctive entity because of its characteristic histology,
proliferation kinetics and behavior. Main in 1970 described, collateral variant of
Keratocystic Odontogenic Tumor, which presents adjacent to the roots of the teeth
usually in the mandibular premolar region and radiologically is indistinguishable
from the lateral periodontal cyst and gingival cyst.
