Odontomas are the most common odontogenic tumors. Intraosseous odontome rarely erupt and very few cases have been reported in the literature. Here we are reporting a case of large erupted complex odontoma in the posterior maxilla, associated with an impacted second molar that caused secondary symptoms like pain and swelling. This case is significant as there are very few reports of complex odon...

Odontomas are the most common type of odontogenic tumors. They are included under the benign calcified odontogenic tumors. Odontomas are basically classified into two types, complex and compound odontomes. Various theories or etiological factors are been quoted for the occurrence of odontomes. Generally, they are asymptomatic. Occasionally, signs and symptoms relating to their presence do occur...

OBJECTIVES Odontogenic tumours comprise a large heterogeneous group of lesions originating from odontogenic epithelium and/or ectomesenchyme and its vestiges. The aim of this study was to analyze odontogenic tumours in children and adolescents seen at a tertiary institution in South Western Nigeria and compare with results from previous studies. MATERIAL AND METHODS Archival records of the De...

Pathogenesis of odontogenic tumors is not well known. It is important to identify genetic deregulations and molecular alterations. This study aimed to investigate, through bioinformatic analysis, the possible genes involved in the pathogenesis of ameloblastoma (AM) and keratocystic odontogenic tumor (KCOT). Genes involved in the pathogenesis of AM and KCOT were identified in GeneCards. Gene lis...

Ameloblastic fibrodentinoma is a benign odontogenic tumor belonging to the category of "odontogenic epithelium with odontogenic ectomesenchyme" along with recognition of induction in the form of dentin in atypical or dysplastic forms. The biological behaviour of ameloblastic fibrodentinoma is not very different from ameloblastic fibroma; hence, it is treated similarly by conservative procedures...

Introduction Ameloblastoma is an uncommon epithelial odontogenic neoplasm that is nonmineralized, locally aggressive and in most cases it is benign. Ameloblastoma accounts for approximately 10% of all tumors that originate in the maxilla and mandible. It often presents as a slow growing, painless swelling, causing expansion of the cortical bone, perforation of the lingual and/or buccal plates a...

Handlers and his colleagus described Central Odontogenic Fibroma (COF) in 1991, as an extremely rare benign odontogenic tumor that is derived from dental mesenchymal tissue. Its accounts for about 0.1% of all odontogenic tumors. COF is an asymptomatic, slow growing lesion, usually occuring in adults and has a female predilection. This article presents a case of COF in a 35-year-old male, on the...

The Glandular Odontogenic Cyst (GOC) is a rare developmental odontogenic cyst that occurs 75% of the time in the mandible and rarely presents in persons under 20 years of age [1]. The GOC was originally described by Padayachee and Van Wyk [2] in 1987 who reported on two cases of multilocular mandibular cysts with features of both Botryoid Odontogenic Cyst (BOC)and central mucoepidermoid tumor (...

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...
