Odontogenic tumors develop in the jaw bones from the odontogenic tissue-oral epithelium in tooth germ, enamel organ, dental papilla, reduced enamel epithelium, remnants of Hertwig's root sheath or dental lamina, and so forth. Hence, a bewildering variety of tumors are encountered in the maxilla and mandible. Ameloblastoma is the second most common odontogenic neoplasm after odontomes, and it ha...

Calcifying epithelial odontogenic tumor (CEOT) is a rare benign, but locally infiltrating odontogenic neoplasm. It accounts for less than 1% of all odontogenic tumors. This is a case report of recurrent CEOT in the maxilla. A 35-year-old patient reported after three years of surgical excision of the lesion, with a recurrence. It is of particular concern because of its anatomic location in the m...

Teeth are present in nearly all vertebrate ani mals except turtles and birds, but tumors of these structures are seldom reported (7). Recently, we had the opportunity to examine the head of a large adult chinook salmon, Oncorhynchus Wzawytscha, and a photograph and histological see tions of a second one. Both fish were taken from displayed innumerable tumors on all tooth-bear ing surfaces. The ...

Odontogenic myxomas are rare odontogenic tumors of jaw characterised by accumulation of mucoid ground substance with little collagen. Peripheral odontogenic myxoma (POM) is extra-osseous variant of odontogenic myxomas, occurring solely in the soft tissue covering the tooth bearing portion of jaws. POM is exceedingly rare, less than 10 cases have been published till date. A case of POM is report...

calcifying epithelial odontogenic tumor is a rare odontogenic neoplasm. its occurrence in the maxillary sinus is very rare. maxillary tumors tend to be locally aggressive and may rapidly involve the surrounding vital structures.  we report a case of calcifying epithelial odontogenic tumor involving maxillary sinus in a 48 years old female patient with the oral mucosal involvement. the purpose o...

Background: Impacted tooth is common in dental practice. Dentists usually remove them if they are associated with any pathologic sign or symptom. The challenge is whether to extract the asymptomatic tooth or not. This study was conducted to determine the association between developmental odontogenic cysts and tumors and impacted and unerupted teeth, if left untreated.    Methods: In ...

Introduction: Adenomatoid odontogenic tumor since years has been a subject for diligent research by Oral Medicine and Radiologists and Oral Pathologists in the past. Adenomatoid odontogenic tumor is a benign hamartomatous slow growing neoplasm of epithelial origin composed of odontogenic epithelium in a variety of histoarchitectural patterns, embedded in a mature connective tissue stroma and ch...

Adenomatoid odontogenic tumor is a relatively uncommon distinct odontogenic neoplasm. It is an uncommon tumor of odontogenic origin with varying number of ductlike structures and inductive changes in the stroma. It is a benign and slow growing epithelial tumor and represents 3% of all odontogenic tumors. Its occurrence is more common in anterior region of the maxilla than mandible. Most of the ...

PURPOSE The objective of this study was to evaluate the diagnostic concordance characteristics of oral cavity lesions by comparing the clinical diagnosis of the lesions with the histopathologic diagnosis. MATERIAL AND METHOD A retrospective analysis was conducted on the patients, who were admitted with oral cavity pathology and underwent biopsy procedure between 2007 and 2011. The oral cavity...

OBJECTIVE The aim of this study is to evaluate the caveolin-1 expression in a group of odontogenic cysts and tumors. MATERIAL AND METHOD In this cross-sectional study, the expression of caveolin-1 was evaluated immunohistochemically in 75 samples including 18 cases of dentigerous cyst, 18 odontogenic keratocysts, 3 orthokeratinized odontogenic cysts, 2 calcifying odontogenic cysts and 34 amel...
