Osteoblastoma is a rare benign bone-forming neoplasm which rarely affects the jaws. Due to the rarity and wide range of clinical, radiographic, and histopathological findings, the diagnosis of gnathic osteoblastoma can be challenging. The authors report here an unusual case of osteoblastoma in the periapical region of maxillary molars. An 18-year-old woman presented with pain and swelling of th...

BACKGROUND/AIMS some studies have reported controversial results when comparing the gastrointestinal transit between diabetic and healthy individuals. Therefore, we compared the gastrointestinal transit of radiopaque particles between diabetic and non-diabetic healthy individuals. METHODS abdominal radiographies were performed for 45 type 2 diabetes mellitus patients and 35 healthy individual...

a case of maxillary antrolith in a 14-year-old girl is presented. a radiopaque mass, thought to be a supernumerary tooth, was incidentally found on a panoramic radiograph obtained for orthodontic purposes. during surgical exploration the maxillary sinus was penetrated and 6 calcified masses were discovered. histopathologic analysis revealed a calcium deposition around a necrotic mass.

The efficacy of the laryngeal reflex during dental treatment in two groups of children was tested using propyliodone 10ml. In 25 children not specially afraid of dental treatment there was no aspiration of radiopaque dye into the larynx or chest. A similar group of 25 anxious children treated using oxygen—nitrous oxide sedation (relative analgesia) were examined in the same way; there was no as...

The controlled precipitation of strontium fluoroapatite crystals was studied in four base glass compositions derived from the SiO2-Al2O3-Y2O3-SrO-Na2O-K2O/Rb2O/Cs2O-P2O5-F system. The crystal phase formation of these glasses and the main properties of the glass-ceramics, such as thermal and optical properties and radiopacity were compared with a fifth, a reference glass-ceramic. The reference g...

INTRODUCTION TO RADIOLOGIC DIAGNOSIS OF DISEASE OF THE ORAL AND MAXILLOFACIAL REGION ---GUIDELINES --- Introduction •Adherence to the following guidelines is essential for accurate radiographic interpretation and development of a differential diagnosis: •Images/radiographs of good quality. •Intimate working knowledge of osseous and soft tissue anatomy, radiographic anatomy, and basic nature ...

A 9-month-old Holstein heifer with a history of severely poor growth presented diarrhoea. On physical examination, metallic pinging sound was heard on the simultaneous percussion and auscultation left trunk. cranial abdominal radiography, contour gas-filled balloon-like abomasum wall delineated, which elevated to dorsal abdomen. Radiopaque sand at bottom had been pulled up caudodorsally by abom...

AIMS AND OBJECTIVES To study the clinical, histological features of peripheral and central ossifying fibromas and also to compare between them. MATERIALS AND METHODS The sample comprised a total 50 cases of ossifying fibromas [25 central ossifying fibromas (COF) and 25 peripheral ossifying fibromas (POF)] inclusive of cemento-ossifying fibromas. RESULTS The mean age is 28.2 years in POF and...
