BACKGROUND The keratocystic odontogenic tumor (KCOT) is a relatively rare, benign neoplasm which develops in the maxilla or mandible, arising from the dental lamina or basal cells of the oral epithelium. It is often found incidentally and brings about late symptoms as it does not cause bone distension for a long time. CASE REPORT The presented case is of a young woman with a giant keratocysti...

Dentigerous cyst is a development odontogenic cyst, which apparently develops by accumulation of fluid between reduced enamel epithelium and the tooth crown of an unerupted tooth. It is one of the most prevalent types of odontogenic cysts associated with an erupted, developing or impacted tooth, particularly the mandibular 3rd molars, the other teeth that are commonly affected are maxillary can...

During embryonic organogenesis, the odontogenic potential resides in dental mesenchyme from the bud stage until birth. Mouse dental mesenchymal cells (mDMCs) isolated from the inductive dental mesenchyme of developing molars are frequently used in the context of tooth development and regeneration. We wondered if and how the odontogenic potential could be retained when mDMCs were cultured in vit...

Markers of cell proliferation are widely used as diagnostic and prognostic tools. Coincident estimation these markers increases the precise evaluation proliferative status different tissues can also be helpful in determining progression, aggressiveness prognosis lesions. The current study investigated expression PCNA MCM3 40 formalin fixed paraffin embedded tissue blocks odontogenic keratocyst ...

Abstract Ameloblastic fibroma is a relatively rare benign odontogenic tumor with two neoplastic components both epithelial and ectomesenchymal. A 10-year-old girl was referred to a dentist for routine dental treatments for evaluation of the distance between mandibular right first permanent molar and mandibular right second deciduous molar and it was associated with an undesirable backward mov...

Introduction Odontogenic epithelium is responsible for tooth development under physiologic conditions and can give rise to tumors or cysts in the jaws (1-3). Ameloblastoma is the most frequently encountered tumor arising from odontogenic epithelium and is characterized by a benign but locally invasive behavior with a high tendency to recur (2, 4). Histologically, ameloblastoma shows considerabl...

Dentinogenic ghost cell tumor (DGCT) is an uncommon locally invasive odontogenic tumor regarded by many as a variant of calcifying odontogenic cyst. The peripheral variant of this clinical rarity appears as a well-circumscribed mass mimicking a nonspecific gingival enlargement. Microscopic appearance of odontogenic epithelium admixed with focal areas of dentinoid formation and sheets of ghost c...

INTRODUCTION Oral verrucous carcinoma (OVC) is a rare malignancy of the oral cavity that was first described by Ackerman. This tumor is a well-differentiated low-grade, slow growing cancer that is locally invasive without metastasis. Ameloblastoma is one of the most common odontogenic tumors, which originates from the odontogenic epithelium. Verrucous carcinoma along with central ambloblastoma ...

Objective. We report the first utilisation of transnasal marsupialization to treat a keratocystic odontogenic tumor in the maxillary sinus of a 37-year-old man. Case Report. A 37-year-old man presented with a nasal discharge and right odontalgia. Computed tomography revealed an expanding cystic lesion with a calcificated wall containing an impacted tooth in the right maxillary sinus. The diagno...

Introduction. We report a rare case of unicystic ameloblastoma (UA) of mandible which showed multilocular radiolucency on the left side of mandible on radiographic examination which is very unusual, and the majority of the cases of UAs till date has been reported of unilocular radiolucency. On histopathological examination, an odontogenic cystic lining that proliferates that intraluminally rese...
