Objective The aim of this retrospective study was to perform an epidemiological analysis of all odontogenic tumors treated in the University Hospitals "Ospedali Riuniti" in Ancona and "Policlinico" in Bari, from 1990 to 2015. Materials and methods A retrospective survey of 277 patients treated for odontogenic tumors from 1990 to 2015 was performed. Data were retrieved from the archives of the...

BACKGROUND Cysts of the jaws constitute an important pathology in the oral and maxillofacial region and are broadly classified as odontogenic and non-odontogenic. Objective of this study was to document the clinical and radiographic presentation of odontogenic cysts at a tertiary care centre. METHODS In this descriptive case-series, patients presenting with features of suspected cystic lesion...

Objective: Odontogenic tumors show a distinct geographic variation. In 2005 a new WHO classification was published which included odontogenic keratocyst as one of the odontogenic tumors, renaming it as a keratocystic odontogenic tumor. To our knowledge there are only few studies based on 2005 classification in Asian subcontinent. This study was done to determine the relative frequency of odonto...

UNLABELLED Statement of the Problem : Ameloblastoma is the most common odontogenic tumor which is slow-growing, locally invasive and exhibit specific biologic behavior and high recurrence rate. Likewise, odontogenic keratocyst is a developmental odontogenic cyst that has a high recurrence rate and aggressive behavior. There are limited studies considering the relationship between the angiogenes...

This case report describes a rare case of an adenomatoid odontogenic tumor (AOT) arising in the mandibular third molar region of a 20-year-old female. The tumor was a well-circumscribed intraosseous lesion with an embedded tooth. Histologically, the induction of extensive globular calcification was evident in addition to the characteristic histological features of AOT. The present case lends su...

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...

P63 may have a role in tumorigenesis and cytodifferentiation of odontogenic lesions. We investigated the immunohistochemical expression of P63 in a total of 30 cases of odontogenic cysts and tumors. The percentage of positive cells was calculated in the lining of odontogenic cysts and islands of ameloblastoma. P63 expression was evident in all types of odontogenic lesions. P63 was expressed thr...

Calcifying epithelial odontogenic tumors (CEOTs) and ghost cell odontogenic tumors (GCOTs) are characteristic odontogenic origin epithelial tumors which produce calcifying materials from transformed epithelial tumor cells. CEOT is a benign odontogenic tumor composed of polygonal epithelial tumor cells that show retrogressive calcific changes, amyloid-like deposition, and clear cytoplasm. Differ...

a 16-years-old female patient with painless swelling of the right side of mandible is described. she noticed the swelling from two years ago, without painful symptoms. axial ct imaging showed buccal expansion with intact buccal and lingual cortical bone. the report of incisional biopsy was central odontogenic fibroma. under general anesthesia the lesion was removed after ostectomy of buccal cor...
