Glandular odontogenic cyst (GOC) is an uncommon developmental cyst. It accounts for 0.012% to 1.3% of all the jaw cysts; its prevalence is 0.17%. It was described by Gardner et al. in 1988 as a distinct entity. GOC has a slight predilection for mandible and affect more commonly in the middle-aged patients. Radiographic and clinical features of this cyst are not pathognomonic or specific. Only t...

Adenomatoid odontogenic tumor (AOT) is an uncommon tumor of odontogenic origin and often misdiagnosed as an odontogenic cyst. It is predominantly found in young female patients, located more often in maxilla, and in most cases associated with an unerupted permanent tooth. There are three variants of AOT namely follicular, extra follicular, and peripheral. We report an unusual case of extrafolli...

A dentigerous cyst is a benign odontogenic cyst that is associated with the crown of an unerupted permanent tooth. This report describes a conservative approach to treatment using a customised removable appliance for managing a large dentigerous cyst in a 7-year-old female. At the 2-year follow-up, healing of the lesion and ossification of the bony defect was observed.

Unicystic ameloblastoma is a rare, benign, locally invasive odontogenic neoplasm of young age that shows clinical, radiographical or gross features of an odontogenic cyst, but it histologically shows typical ameloblastomatous epithelium lining part of the cyst cavity, with or without luminal and/or mural tumor growth. A case of asymptomatic unicystic ameloblastoma in an 11- year-old-female, who...

Calcifying odontogenic cyst is considered as a rare lesion and accounts for 1% of jaw cysts. It represents a heterogeneous group of lesions which exhibit a variety of clinicopathologic and behavioral features. It has been categorized as cyst and neoplasm. Even after several classification and subclassification, COC remains an enigma. WHO classification 2005 has reclassified the lesion as calcif...

In recent years, there have been published clinical reports dealing with cysts or tumors of the odontogenic character the extract of which revealed pathologic keratinizing or calcifying changes in the light of histopathologic examination Cl, 6, 8, 9, 10, 11, 12). These pathologic changes are said to give quite different histopathologic findings from those of the radicular cyst, follicular cyst ...

  Background and Objectives: There are a few studies on histopathologic type of oral lesions especially from Iran. The aim of this study was to survey the oral lesions in Babol, northern Iran. Methods: The histopathology records were retrospectively reviewed for all lesions of oral cavity and jaws, during the years 1990 to 2009. The data were collected from the archive of pathology and analyz...

In 2005, odontogenic cyst was classified as keratocyst odontogenic tumor due to being aggressive and recurrent. The keratocyst odontogenic tumor has characteristics, with slow development, does not cause metastases and provides great bone destruction. The aim of this study was to discuss the aspects regarding the diagnosis, prognosis and treatment of odontogenic keratocyst tumor, through the re...

Adenomatoid odontogenic tumor (AOT) is a rare odontogenic tumor often misdiagnosed as odontogenic cyst. AOT is predominantly found in female patients, which usually arise in the second or third decade and is located more often in the maxilla than mandible and often associated with an unerupted permanent tooth. However, AOT frequently resembles other odontogenic lesions such as dentigerous cysts...

A calcifying cystic odontogenic tumor (CCOT) is a proliferation of odontogenic epithelium and scattered nests of ghost cells and calcifications that may form the lining of a cyst, or present as a solid mass. It was previously described by Gorlin et al in 1962 as a calcifying odontogenic cyst. Dentigerous cysts are developmental odontogenic jaw cysts, commonly manifesting in the second and third...
