The purpose of this project was to characterize the histopathology of radiolucent furcation lesions associated with primary molars which had received pulpotomy treatment. Twenty-four pulpotomy-treated primary molars which displayed radiolucent lesions in the root furcation suggesting unsuccessful outcome were extracted. Pretreatment radiographs were available for 6 teeth and none had evidence o...

We have investigated the mid-term outcome of total shoulder replacement using a keeled cemented glenoid component and a modern cementing technique with regard to the causes of failure and loosening of the components. Between 1997 and 2003 we performed 96 total shoulder replacements on 88 patients, 24 men and 64 women with a mean age of 69.7 years (31 to 82). The minimum follow-up was five years...

Carbon-fiber-reinforced polyetheretherketone implants offer several benefits over traditional metal implants. Their radiolucent property permits improved, artifact-free radiographic imaging. Their lower modulus of elasticity better matches that of bone. Their fatigue strength is greater than most metal implants. This article reviews the use of these implants in orthopedic surgery, including tre...

In children with acquired oesophageal strictures * even without a definite history of ingestion, there could be a foreign body in the oesophagus * diagnostic work-up in cases of suspected 'occult foreign body' still presents difficulties, particularly if the foreign body is radiolucent * the chronic presence of a foreign body in the oesophagus may lead to severe and unsuspected complications a ...

Extracorporeal shock wave lithotripsy (ESWL) revolutionized the treatment of urolithiasis and gradually became the favorite treatment option so that today it is considered to be the first line of treatment for more than 75% of the patients with urolithiasis. The purpose of this study was the assessment of the therapeutic efficiency, complications and limitations of ESWL in urolithiasis in the i...

An intraosseous, slightly painful swelling was noted upon clinical examination of an eight-year-old girl. The swelling was of an unspecified duration and slow growing in nature. A radiopaque mass with a radiolucent periphery attached to the roots of the mandibular right second primary molar was noted on a periapical radiograph. The diagnosis of cementoblastoma was verified by the histologic ass...

PEEK has been implemented in various orthopaedic applications due to its many beneficial mechanical, tribological, and radiolucent properties. These properties can be further tailored by introducing fillers into the PEEK matrix. In this work, graphene has been incorporated due to its high mechanical resistance, intrinsic stiffness, and lubricating properties [2].

Dysphagia is a well-recognized complication of stroke. We report two cases of dysphagia in stroke patients caused by the pharyngeal impaction of dental prostheses. Radiologic identification of such impaction is unreliable due to the increasing use of radiolucent material in dental prostheses. We recommend direct or indirect laryngoscopy to exclude foreign body impaction in all patients complain...

Titanium coated PEEK cages incorporate the advantages of both PEEK, which offers a native-like elastic modulus and a radiolucent behaviour, and Titanium which provides improved biocompatibility and promotes osseointegration. In this study, we evaluated the response of Titanium plasma sprayed PEEK cages to provide safe support of the lumbar spine and promote bony fusion.
