Adenomatoid odontogenic tumor (AOT), a benign (hamartomatous) lesion of odontogenic origin, is an uncommon tumor which affects mainly females in the second decade. This lesion is most commonly associated with an impacted maxillary canine. This paper reported a case of AOT, in a 16-year-old female, associated with an impacted maxillary left lateral incisor. The evolution of this tumor was follow...

The squamous odontogenic tumor (SOT) was first described by Pullon, et al. in 1975 [1]. SOT is a benign epithelial odontogenic tumor which usually occurs intraosseously and develops in the periodontal ligament between the roots of vital erupted permanent teeth.1This slow growing tumor presents with very few clinical findings and affects the mandible more often than the maxilla. To date, fewer t...

OBJECTIVE the role of p53 expression in odontogenic lesions has not been fully determined, but has been associated with cell proliferation. The purpose of this study was to analyze p53 and proliferating cell nuclear antigen (PCNA) expression in 4 different odontogenic lesions. DESIGN expression of p53 and PCNA was analyzed in radicular and dentigerous cysts, odontogenic keratocysts, and calci...

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...

Start developing at 20 weeks gestation. Cysts and tumors in the mandible: a retrospective clinical trial. Cystic 6, intraosseous tumors of odontogenic origin, with a characteristic lining.July 19: Odontogenic Cysts, Tumors, and Related Jaw Lesions. Odontogenic cysts are defined as epithelial-lined structures derived from odontogenic.Overall, odontogenic tumors are rare and form only a small pro...

Background. The aim of this study was to investigate myofibroblast (MF) density in a broad spectrum of odontogenic cysts and tumors and the relation between the density of MFs and the clinical behavior of these lesions. Methods. A total of 105 cases of odontogenic lesions, including unicystic ameloblastoma (UAM), solid ameloblastoma (SA), odontogenic keratocyst (OKC), dentigerous cyst (DC), rad...

Oral and maxillofacial pathology has paramount importance in connecting basic science and clinical features; progress in this field will improve diagnosis and treatment. Although the prevalence of odontogenic tumors varies in different geographic sites, there are no reports in English on the relative frequency of odontogenic tumors in Iran. In the present 30-year retrospective study, the case r...

Central odontogenic fibroma (COF) represents a rare group of benign odontogenic tumor, while dentigerous cyst (DC), on the other hand, is the odontogenic cyst that encloses the crown of an unerupted tooth. A combination of COF and DC is rare and not reported in literature till date. The aim of this paper is to report a case of COF occurring concurrently with DC. The simultaneous occurrence of C...

The purpose of this study was to report an extrafollicular adenomatoid odontogenic tumor in the mandibular anterior region in a patient. A 15 year-old female with a painless swelling in the mandibular anterior region was referred to our clinic. Fine needle aspiration yielded no fluid. Periapical, panoramic and computer tomography scans showed circumscribed radiolucent area with fine calcificati...

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...
