Primordial odontogenic tumor
(POT) has been included as a new entity in a recent WHO (2017) classification of odontogenic tumors
under benign mixed mesenchymal and epithelial tumors.
Lesion location and distribution within the jaw is also important, as odontogenic tumors
are in approximation with the root apex or crown of a tooth and are more focal.
We found a statistically significant difference in the ratio of Ki67-positive cells in the entire layer between the keratocystic odontogenic tumors
and both the dentigerous cysts and the radicular cysts.
8% of all odontogenic tumors
, ranking them third among odontogenic tumors
in Mexico: a collaborative retrospective study of 349 cases Oral Surg Oral Med Oral Pathol Oral Radiol Endod 1997; 84: 672-5.
8] The peripheral odontogenic fibroma must be differentiated histologically from POF, which is a reactive lesion, and from the peripheral ameloblastoma and the calcifying epithelial odontogenic tumor
which are benign odontogenic tumors
Based on the diagnostic criteria, biological behavior and diversity of the odontogenic lesions, different classification plans have been established however, the World Health Organization's histological typing of odontogenic tumors
, updated in 2005, has an upper edge over the other and still in use for classification of odontogenic lesions.
Purpose: The aim of this retrospective study is to determine the radiological features of keratocystic odontogenic tumors
(KCOT) using cone-beam computed tomography (CBCT).
It has been speculated that odontogenic tumors
are associated with development of mandibular permanent incisors because they appear at an early age (Tetens et al.
The disruptions in the BMP expression may lead to the formation of odontogenic tumors
, including denticles .
Objective: To determine calretinin expression by immunohistochemistry in ameloblastoma and keratocystic odontogenic tumors
(KCOT) and to document the use of calretinin as a differentiating marker between the two lesions.
