Odontogenic tumors contain a heterogeneous collection of lesions that are categorized from hamartomas to benign and malignant neoplasms of inconstant aggressiveness. Odontogenic tumors are usually extraordinary with assessed frequency of short of 0.5 cases/100,000 population for every year. The lesions such as odontogenic tumors are inferred from the components of the tooth-structuring contrapt...

Background: Odontogenic tumors are derived from the epithelial and/or mesenchymal remnants of the tooth-forming apparatus. Therefore, they are found exclusively in tooth-bearing areas. Similar to other neoplasms in the body, odontogenic tumors tend to histologically mimic the cell or tissue of origin. Case history: A 5-year-old boy presented with a chief complaint of pain in the mandible whi...

STATEMENT OF THE PROBLEM Odontogenic cysts and tumors are the most frequent osseous destructive lesions of the jaws; however, there is little information regarding the relative frequency of these lesions among the Iranian population. PURPOSE The purpose of this study was to determine the distribution of clinically and histologically- diagnosed odontogenic cysts and tumors during a period of 1...

OBJECTIVE This article presents the results of a retrospective study of the frequency and classification of odontogenic tumors recorded at four centers of diagnostic pathology in Rio de Janeiro, Brazil. STUDY DESIGN All medical records and microscopic slides of odontogenic tumor specimens for the years 1997 to 2007 were retrieved from the files of four services of diagnostic pathology in Rio ...

Abstract Introduction: Pigmented odontogenic lesions are rare; to date, only 60 cases have been reported in the literature. Melanocytes have been detected in a wide variety of odontogenic lesions. Several studies have discussed melanocyte presence and melanin production in odontogenic lesions, but its origin is still unclear. Therefore, the present systematic review aimed to gather information...

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...

p53 and pcna expression in keratocystic odontogenic tumors compared with selected odontogenic cysts summary: the aim of this study was to evaluate p53 and pcna expression in different odontogenic lesions regarding their different clinical behaviors. slices prepared from 94 paraffin-embedded tissue blocks (25 radicular cysts (rc), 23 dentigerous cysts (dc), 23 keratocystic odontogenic tumors (kc...

BACKGROUND AND PURPOSE Ameloblastomas and keratocystic odontogenic tumors are major aggressive odontogenic tumors in the maxillomandibular regions, but the differentiation between these 2 tumors is frequently ineffective based on only conventional CT and MR imaging findings. Here, we evaluated diffusion-weighted MR imaging for the differentiation of these 2 odontogenic tumors. MATERIALS AND M...

BACKGROUND The purpose of this study was to assess and compare angiogenesis in ameloblastoma, keratocystic odontogenic tumors, dentigerous cysts, and normal oral mucosa. METHODS Angiogenesis was assessed in 28 ameloblastoma-36 keratocystic odontogenic tumors, 28 dentigerous cysts, and 19 normal oral mucosa by measuring the mean vascular density (MVD), total vascular area (TVA) and mean vascul...
