The main goal of this study was to identify the main distinctive radiographic characteristics of different unilocular radiolucent mandibular lesions based on the criteria used by different groups of specialists during the process of radiograph interpretation to arrive at a correct diagnosis. A total of 24 panoramic radiographs were selected exhibiting the following lesions: ameloblastoma, kerat...

Recent improvements in digital C-arm radiographic units permit the safe and effective performance of cerebral angiography in the operating room. Intraoperative cerebral angiography, in turn, facilitates more effective aneurysm surgery and arteriovenous malformation therapy (1 , 2]. A variety of radiolucent carbon fiber head holders are now available for use in neurosurgical procedures that invo...

A benign bone neoplasm known as an osseous fibroma is frequently referred fibro-osseous lesion. It has a stronger preference for females and thought to have originated from periodontal membrane. Maxilla less often afflicted than the mandible. This made up of highly cellular, fibrous tissue with varied levels calcified tissue, which may resemble cementum, bone, or both. Depending on degree calci...

It is crucial to understand the distribution of embolic agents inside target liver during and after the hepatic portal vein embolization (PVE) procedure. For a long time, the problem has not been well solved due to the radiolucency of embolic agents and the resolution limitation of conventional radiography. In this study, we first reported use of fluorescent carboxyl microspheres (FCM) as radio...

The orthokeratinized odontogenic cyst (OOC) is a rare developmental odontogenic cyst that has been considered as a variant of the keratocystic odontogenic tumour (KCOT) until Wright (1981) defined it as a different entity. Surgery is the usual treatment, and recurrence or association with Gorlin-Goltz syndrome has rarely been described. In this report, we presented three cases of this pathology...

Eighty-six nonhinged total knee arthroplasties performed between 1971 and 1981 have been reviewed. Fifty-one were of the geometric type and 35 of the anametric type. The use of both units resulted in a statistically and clinically significant improvement in preoperative pain and an increase in functional activities. Three of 51 geometric units developed loose components that required revision. ...

Recent in vitro work has shown that sealing the acetabular notch with bone graft in bovine acetabulum samples results in improved cement penetration in the acetabular bone during total hip arthroplasty. Successful sealing of the notch may be identified on postoperative films by a lack of cement extrusion. This study aimed to assess the clinical effectiveness of this technique in preventing ceme...
