Central odontogenic fibroma is a very rare benign odontogenic tumour characterized by a fibrous mature stroma with variable strands or islands of inactive-looking odontogenic epithelium. Our aim is to report a case of a central odontogenic fibroma and describe the clinical usefulness of Er:YAG laser for the surgical treatment of this tumour. A 74-year-old woman presented with an expansive lesio...

Introduction: Peripheral odontogenic tumors are rare and there is no valid information of the frequency of them in the literature. This study aims to obtain the frequency of these tumors. Materials and Methods: The files of oral and maxillofacial pathology (microscopic reports and slides), faculty of dentistry, Shahid Beheshti University of medical sciences served as the source of the material...

Central odontogenic fibroma (COF) is an extremely rare benign tumor that accounts for 0.1% of all odontogenic tumors. It is a lesion associated with the crown of an unerupted tooth resembling dentigerous cyst. In this report, a 10-year-old male patient is presented, who was diagnosed with central odontogenic fibroma of simple type from clinical, radiological, and histopathological findings.

The odontogenic fibroma is a rare, benign tumor of mesodermal origin, and one of the most ill-defined and least understood of all odontogenic neoplasms. 1 It presently is thought to originate from either dental follicle, periodontal ligament, or dental papilla. 2 Bhaskar reported the lesion as being the most common odontogenic tumor comprising approximately 23°70 of all odontogenic lesions. 3 T...

A spontaneous ameloblastic fibroma was found in a 9-week-old guinea pig. Histopathologically, neoplastic cells consisted of two components: an odontogenic epithelium and odontogenic mesenchyme. The odontogenic epithelium formed strands, nests and islands that were interspersed within the odontogenic mesenchyme. In the marginal region, odontoblasts and scant dysplastic eosinophilic material were...

Odontogenic fibroma (OF) is considered an unusual, benign mesenchymal neoplasm and one of the most little-understood lesions amongst all odontogenic neoplasms. The incidence rate of the tumor is from 0% to 5.5%. WHO classified them into intraosseous or central and extraosseous or peripheral variants. It chiefly consists of fibroblastic tissue with an inconsistent amount of inactive appearing od...

Intra-osseous fibromas of the jaw are classified by origin. Intra-osseous odontogenic fibromas have odontogenic epithelia, while desmoplastic fibromas do not. However, it is often difficult to determine the odontogenic origin for central fibromas. Three subjects with a diagnosis of intra-osseous fibroma were examined. Case 1 was a 35-year-old man found to have a panoramic radiograph from the ri...

BACKGROUND Giant cell fibroma is a type of fibrous tumour of the oral mucosa which rarely affects children under the age of 10. The purpose of this paper was to contribute two clinically and histologically documented cases of giant cell fibroma in the free gingiva of a 7 and 6 year old boys. METHODS Both nodules were presented in the mandibular anterior region. In the differential diagnosis s...
