An ectopic tooth is an eruption of a into abnormal location, such as the palate, sinonasal cavities, mandibular condyle, coronoid process, orbit, or skin. It can be found incidentally presented with variety symptoms, unilateral nasal obstruction, epistaxis, rhinorrhea, chronic congestion, headache, facial pain. Ectopic teeth are most commonly supernumerary, but may also deciduous permanent teet...

The calcifying odontogenic cyst represents a heterogeneous group of lesions that exhibits a variety of clinicopathologic and behavioral features. Therefore, a proper categorization of the cases is needed for better understanding of each variant. Ameloblastoma is one of the well-known odontogenic tumors that could be associated with calcifying odontogenic cyst. Very few cases of ameloblastomatou...

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 (...

Calcifying epithelial odontogenic tumor (Pindborg tumor), is a rare benign odontogenic neoplasm representing about 0.4-3% of all odontogenic tumors. This tumor more frequently affects adults in the age range of 20-60 years, with a peak incidence in the 5th decade of life. Calcifying epithelial odontogenic tumour has a much lower recurrence rate than ameloblastoma and malignant transformation, a...

OBJECTIVE To determine the distribution of odontogenic cysts diagnosed histologically over a period of 38 years in a Brazilian population according to age, gender and site affected and to compare these data with previously reported studies from other countries. STUDY DESIGN A total of 1019 cases of odontogenic cysts diagnosed between 1970 and 2007 were studied. Clinical features obtained from...

Calcifying epithelial odontogenic tumors are rare odontogenic neoplasms that account for approximately one percent of all odontogenic tumors. Extra osseous variant is very rare with very few cases being reported in literature Peripheral Calcifying epithelial odontogenic tumor (CEOT) commonly resemble oral hyperplastic or reactive lesions and are histologically similar to their intraosseous coun...

Background and aims. Odontogenic cysts and tumors have a wide spectrum of clinical characteristics that lead to the different management strategies. Since definite diagnosis is difficult in some cases, it has been suggested that CD56 may be a candidate marker for definitive diagnosis of some odontogenic tumors. The present study was designed to examine CD56 expression in lesions with histopatho...

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...
