Fungus balls are tangled mats of hyphae that are often found in the maxillary sinus. In approximately half of affected patients, radiologic evaluation will reveal areas of hyperdensity within soft-tissue masses. Histopathologic examination will reveal no invasion of the mucosa and no granulomatous reactions. Surgical removal is sufficient because fungus balls are not known to recur. We describe...

Filler –matrix coupling determines, to a large extent, the mechanical strength and clinical longevity of dental composites. Incorporation of filler into resin matrix greatly influences and improves material properties provided that filler particles are bonded to polymer matrix or otherwise it may actually weaken the resin. Benefits of filler content presence are increased hardness, strength, ra...

Amalgam tattoos are common exogenous pigmented lesions of the oral mucosa occurring mainly by inadvertent placement of amalgam particles into soft tissues. The diagnosis of amalgam tattoo is simple, usually based on clinical findings associated with presence or history of amalgam fillings removal. Intraoral X-rays may be helpful in detecting amalgam-related radiopacity. In cases where amalgam t...

Idiopathic osteosclerosis (IO) is described as a localized no expansible radiopacity with unknown etiology. The IO is generally asymptomatic and could appear as round, elliptical or irregular in shape. The internal aspect is usually uniformly radiopaque. IO should be distinguished from condensing osteitis of dental origin, or other alveolar bone related radiopacities such as periapical cemental...

ABSTRACT Among the diseases that cause dyspnea in felines, primary pulmonary neoplasia is rare and tends to affect senile cats. This study reports case of a seven teen year old FeLV infected cat who was diagnosed acinar adenocarcinoma lung kidney metastasis. It presented prostration anorexia hospitalized with pleural effusion. Chest radiography indicated increased radiopacity cranial portion ri...

We present the characteristic plain radiographic and intravenous urographic (IVU) findings of calculus formed over a hair. A 66-year-old man who had been quadriplegic for 40 years because of vertebral injury was admitted for further evaluation of frequent urinary tract infection. Plain radiography showed a linear, serpiginous calcification in the lower abdomen, and IVU revealed a round filling ...

Ceramics are very important in the science of dental biomaterials. Among all dental ceramics, zirconia is in evidence as a dental biomaterial and it is the material of choice in contemporary restorative dentistry. Zirconia has been applied as structural material for dental bridges, crowns, inserts, and implants, mostly because of its biocompatibility, high fracture toughness, and radiopacity. H...

Most of the serious neurologic complications related to angiography are embolic in nature. Meticulous catheter flushing techniques have been suggested to reduce embolic complications [1] . An experimental catheter with a 20-cm-long transparent proximal section has been evaluated to determine its usefulness in monitoring catheter flushing procedures and inadvertent injections of emboli. Catheter...

Increased deposition of cementum is observed in a wide number of both benign and malignant conditions. Many cases are often diagnosed during routine examination as an incidental finding. Diagnosing correctly without confusing it with other similarly appearing lesions, thus avoiding subjecting the patient to unnecessary investigations and stress, is of prime importance. We report one such case, ...
