background: linear endoscopic ultrasonography (eus) is a proven modality for the diagnosis and treatment of different gastrointestinal lesions. the aim of this study was to describe the role of eus-fna in the evaluation of pancreatic and submucosal lesions. materials and methods: over a 1-year period, in a prospective descriptive study, patients referred to naft hospital, underwent linear eus. ...

Invasive cervical resorption is a relatively uncommon form of external root resorption exhibiting no external signs. The resorptive condition is often detected by routine radiographic examination. The clinical features vary from a small defect at the gingival margin to a pink coronal discoloration of the tooth crown resulting in ultimate cavitation of the overlying enamel which is painless unle...

A 3-year-old male patient was referred to the Maxillofacial Surgery Clinic due to a painless swelling of the right palatal region. Conventional radiographs revealed no alteration of the dentition and did not delineate a lesion in the region of interest. Cone-beam tomography depicted small radiopaque, extraosseous deposits inside the palatal space. Histological examination revealed a minute mixe...

We reported a case of a 10-year-old girl with cementifying fibroma and cementoblastoma co-existed in the right mandible. Her right mandible swelled and became asymmetry in one month. Radiographically, a radiopaqueradiolucent lesion in anterior site and a radiopaque mass in posterior site were revealed. With fibrous dysplasia (anterior lesion) and odontoma (posterior lesion) as our initially dia...

RFO, Passo Fundo, v. 17, n. 1, p. 41-45, jan./abr. 2012 Objective: The aim of this present study was to determine the prevalence of developing lesions such as: antral pseudocyst, Stafne bone cavity and elongated stylohyoid complex in patients from the Dentistry Faculty of the Federal University of Pelotas – RS – Brazil. Methodology: A total of 667 panoramic radiographies were observed. Dome-sha...

Calcifying Epithelial Odontogenic Tumor (CEOT) is a rare benign odontogenic tumor that was first described by Pindborg in 1955. It accounts for less than 1% of all odontogenic neoplasms. This lesion is a locally aggressive benign odontogenic neoplasm arising from epithelial tissue. The radiographic appearance is characterized by unior multilocular radiolucent areas with radiopaque masses of var...

odontoma.2,3 Compound odontomas consist of tooth-like structures that radiographically appear as opacities. Complex odontomas comprise a mixture of odontogenic tissues without dental organization.2,4 Clinically, three types of odontomas are recognized in the literature: central (intraosseous) odontoma, peripheral (extraosseous or soft tissue) odontoma, and erupted odontoma.2,5 Odontomas are oft...

Osteomas are benign osteogenic neoplasms or hamartomas with a very slow growth rate. Osteoma is the most common mesenchymal neoplasm of the paranasal sinuses. In the jaws, the mandible is more commonly involved than the maxilla. Osteomas may occur at any age, but most frequently are found in individuals older than 40 years. Although most osteomas are small, some may become large enough to cause...

Osteoblastoma is a rare benign tumor that accounts for less than 1% of all bone tumors. About 10% of osteoblastomas are found in the skull bones and almost half of these cases involve the mandible, especially the posterior segments. This report describes the case of a 27-year-old female patient with a unilocular radiopaque expansive lesion in the left mandible, which had well-delimited margins ...

Florid cemento-osseous dysplasia (FCOD) has been described as a condition that characteristically affects the jaws of middle-aged black women. This condition has also been classified as gigantiform cementoma, chronic sclerosing osteomyelitis, sclerosing osteitis, multiple estenosis and sclerotic cemental masses. It usually exhibits as multiple radiopaque cementum-like masses distributed through...
