Primordial odontogenic tumor (POT) is a rare characterized by variably cellular loose fibrous tissue with areas similar to the dental papilla and covered cuboidal columnar epithelium. We herein report case of POT in 14-year-old boy. Computed tomography (CT) exhibited round cavity defined cortical border circumscribing tooth second molar. However, gross finding was solid mass, not cyst. Histolog...

BACKGROUND Dentigerous cyst is the second most common type of odontogenic cysts that encloses the crown of an unerupted tooth by expansion of its follicle due to the collection of cystic fluid. In view of the capability of these lesions attaining a marked size if not diagnosed early and treated properly, the present study was done based on the clinical and radiographic presentation of the denti...

The aim of this study was to verify the relationship between the radiographically measured width of the pericoronal space (PS) and the microscopic features of the follicle in order to contribute to the diagnosis of small dentigerous cysts and paradental cysts. One hundred and thirty unerupted teeth (UT) and thirty-five partially erupted teeth (PET) were radiographed and extracted. The radiograp...

The mechanism of proliferation and expansion remains unclear. Metalloproteinases (MMPs) are associated to diverse pathological conditions. The aim of the present study was to correlate the radiographic aspect (area) and the presence of MMP-2 and MMP-9 in dentigerous cysts, radicular cysts and keratocystic odontogenic tumors. The radiographic area of each lesion was calculated using the mathemat...

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...

BACKGROUND The purpose of the study was to correlate the provisional diagnosis of pericoronal radiolucencies associated with impacted, embedded, or unerupted teeth with the histopathologic diagnosis, and also to emphasize the importance of early detection for better diagnosis and management. METHODS This is a retrospective study involving 18 cases of pericoronal radiolucencies associated with...

Background: Jaw cysts and cyst-like lesions cause facial deformity, destruction of dental tissues and affect masticatory and phonation functions. These adversely erode patients’ psycho-social status; create low self-esteem and may change one’s facial identity and appearance. Objective: To determine the histopathologic characteristics, variants and demographic pattern of jaw cysts and cyst-like ...

Central hemangioma, a bone destructive lesion, is a benign tumor. Hemangiomas of jaws are rare entity and produces many different radiographic images. Radiographic differential diagnosis includes osteosarcoma, fibrous dysplasia, central giant cell granuloma, ameloblastoma, odontogenic myxoma, multiple myeloma, dentigerous cyst and aneurysmal bone cyst. Since it involves proliferation of blood v...
