Quality aspects of digital radiography in general dental practice.
Swedish dental journal. Supplement, 2007 The number of dentists who have converted from conventional film radiography to digital radiography continues to grow. A digital system has numerous advantages, but there are also many new aspects to consider. The overall aim of this thesis was to study how digital radiography was used in general dental practices.

A digital subtraction technique for dental radiography
Oral Surgery, Oral Medicine, Oral Pathology, 1983The relative accessibility and stability of the teeth facilitate generation of geometrically identical radiographs over a period of time. When such radiographs are digitized with the aid of a TV camera coupled to an analog to digital converter and a computer, it is possible to conveniently produce subtraction images of high diagnostic value.

Digital Radiography in the Dental Practice: An Update
Primary Dental Journal, 2013The implementation of digital imaging in dental practice should be considered. The vast number of advantages of digital imaging include time saving and image manipulation. Dose reduction is a big attraction but in practical terms this might not be fully taken advantage of, as a number of studies suggest.

Is digital better in dental radiography?
Radiation Protection Dosimetry, 2008In Slovenia, dental radiography was the first field in which projection x-ray imaging using digital detectors was done. At present around 30% of intraoral dental x-ray units use digital detectors. Annual test results were analysed to compare digital systems with film-based ones.

Bayesian denoising in digital radiography: A comparison in the dental field
Computerized Medical Imaging and Graphics, 2013We compared two Bayesian denoising algorithms for digital radiographs, based on Total Variation regularization and wavelet decomposition. The comparison was performed on simulated radiographs with different photon counts and frequency content and on real dental radiographs.

Terrorist activity has the potential to cause mass casualties. The number of victims often overwhelms the ability of local jurisdictions to identify the causalities in an accurate and timely fashion. Most identifications are usually made through the comparison of ante mortem dental records with post mortem radiographic and clinical findings ...

Quantitative subtraction with direct digital dental radiography.
Dentomaxillofacial Radiology, 1997To elucidate the accuracy in vitro of quantitative digital subtraction for direct digital dental radiography using a commercially available image analysis system.Images were corrected first for dark current and sensitivity variation among pixels of the CCD sensor (first correction), and corrected further for interimage variations due to the variations ...

Digital Subtraction Radiography for Monitoring Dental Demineralization
Caries Research, 2000The aim of the present study was to evaluate the assessment of progression of demineralization by digital subtraction radiography. In each of 14 extracted human teeth, 2 approximal enamel demineralization lesions were induced in vitro to simulate dental caries.

The missing link in image quality assessment in digital dental radiography
Oral Radiology, 2019Digital radiography is gaining popularity among general dental practitioners. It includes digital intraoral radiography, digital panoramic radiography, digital cephalography, and cone-beam computed tomography. In this study, we focused on the methods to assess image quality of these techniques, except for digital cephalography, in the light of ...

Accuracy of dental calculus detection using digital radiography and image manipulation
Journal of Periodontology, 2020AbstractBackgroundThe aim of this study was to determine if image enhancement improves a clinician's ability to identify the presence of calculus on digital radiographs.MethodsSeventy‐one hopeless teeth were collected from 34 patients. Teeth were stained with 1% methylene blue, the largest interproximal calculus deposit was scored, and photographs of ...
