Two female patients presented with multiple radiolucent lesions noted on panoramic radiography. Cone-beam computed tomography (CBCT) scans confirmed “punched-out” affecting the skull.

OBJECTIVES Practitioners should be aware of the occurrence rate and usual location of radiolucent jaw lesions. The aims of this study were to examine the frequency and location of radiolucent jaw lesions, including apical granulomas, apical cysts, keratocystic odontogenic tumors (KOTs), central giant cell lesions (CGCLs), ameloblastomas, and metastatic lesions, that were submitted for biopsy al...

BACKGROUND Radiolucent lines and sclerotic margins are often seen on knee radiographs taken a year or longer after knee replacement surgery. Histology has shown that the radiolucent zone is predominantly fibrocartilage and the sclerotic margin is lamellar bone. The reasons for their existence are not clearly understood. METHODS A three-dimensional finite element model of the medial half of th...

Purpose In situ fixation for mild to moderate slipped capital femoral epiphysis (SCFE) remains an acceptable treatment methodology in most centers. Satisfactory fixation results have been reported with the procedure using either the fracture table or radiolucent table, both of which allow the hip to be imaged during the procedure. The position of the pin within the center of the femoral head is...

A 13-year-old boy who accidentally ingested an aluminum beverage can pull tab. Neck and chest radiographs did not reveal any foreign body. This case report illustrates poor negative predictive value of conventional for a suspected body demonstrates superiority CT this purpose. In such presentations, it is imperative to have low threshold performing further diagnostic evaluation with due the rel...

cone beam computed tomography is a useful technique for imaging the craniofacial lesions. it produces more realistic images that facilitate interpretation. juvenile ossifying fibroma (jof) is a rare and benign fibro-osseous neoplasm that arises within the craniofacial bones, especially in the maxilla. mandibular lesions can be seen in 10% of the cases.in both jaws, it has a predilection for the...

The purpose of this report is to describe the histopathology of radiolucent lesions associated with pulp necrosis in primary molars. Twenty-one carious, previously untreated, primary molars with radiolucent lesions were extracted with forceps under local anesthesia. If a lesion remained attached to the root, the specimen was transferred to 10% neutral buffered formalin. The sockets were gently ...

CLINICAL PRESENTATION A 22-year-old white female presented with a solitary, well circumscribed, round radiolucency 15 mm in diameter, with a largely sclerotic border in the mandibular midline, seen on Panorex (Fig 1) and occlusal films. The lesion was asymptomatic and of unknown duration, and there was no detectable expansion of the jaw. The incisor teeth were nonrestored, noncarious, and vital...

conclusions we reported a rare case of large residual cyst. dental practitioners should consider this lesion in the differential diagnosis of radiolucent lesions of the jaw bone. case presentation a 59-year-old iranian man complaining of a dull pain in his left side of the mandible after falling down one month ago was referred to the department of oral and maxillofacial pathology, hamadan unive...
