Retrieval of cement-retained implant prostheses can be more demanding than retrieval of screw-retained prostheses. This case report describes a simple and predictable procedure to locate the abutment screw access openings of cementretained implant-supported crowns in cases of fractured ceramic veneer. A conventional periapical radiography image was captured using a digital camera, transferred t...

OBJECTIVE The study was performed to evaluate detection of soft-tissue foreign bodies using conventional radiography (film-screen radiography), computed radiography printed on films (computed radiography-hard copy), and computed radiography displayed on a computer workstation (computed radiography-soft copy). SUBJECTS AND METHODS Fifteen foreign bodies of different size, shape, and compositio...

BACKGROUND Loss of the interproximal dental papilla may cause functional and, especially in the maxillary anterior region, phonetic and severe esthetic problems. The purpose of this study was to investigate whether the distance from the contact point to the bone crest on standardized periapical radiographs of the maxillary anterior teeth could be correlated with the presence of the interproxima...

The possibility of using long film-focus distance radiography as a new screening method for lung cancer diagnosis was investigated. Long-film focus distance radiography produced exceptionally superior image sharpness suitable for use as clinical photographs, at a distance of about FFD (Film-Focus Distance) 20 m. The effective energy was increased by narrowing the radiation spectrum via an air-f...

New digital detectors were developed for medical applications, which have the potential to substitute the X-ray film and revolutionise the radiological technique. Flat panels and imaging plates allow a fast detection of radiographs in a shorter time and with higher dynamic than film applications. The properties of these detectors can be controlled by electronics and exposure conditions. New nam...

i ntroduction: vertical root fracture (vrf) is the longitudinal fracture of the root in endodontically treated teeth. considering the limitations of two-dimensional radiographic images in detection of vrf and introduction of cone-beam computed tomography (cbct), this study was designed to find the sensitivity, specificity and accuracy of cbct and periapical (pa) radiography in detection of vrfs...
