Quality assurance tests for digital radiography in general dental practice
Dental Update, 2014Quality assurance (QA) is essential in dental radiography. Digital radiography is becoming more common in dentistry, so it is important that appropriate QA tests are carried out on the digital equipment, including the viewing monitor. The aim of this article is to outline the tests that can be carried out in dental practice.

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.

A “low‐cost” personal computer (PC) system used to digitize dental radiographs was tested by assessing the accuracy of its subtraction images versus those of “high‐cost” industrial equipment and conventional radiography. Subtraction images were made of artificial lesions in human femur bone and subsequently evaluated by students and teachers.

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 ...

Digital dental radiography needs assessment utilizing the Delphi process.
General dentistry, 2005This article reports the results of a needs assessment using the Delphi process. The purpose of this study was to determine the architecture and equipment (radiographic and computer network) for establishing and supporting an enterprise's vast digital dental radiographic program.

Digital images offer tremendous advantages to dentistry in terms of the potential for lower exposure to patients, absence of darkroom or processing problems, convenience of image enhancement techniques and capacity for remote teledentistry. Digital systems are now able to acquire all types of images including panoramic and cephalometric.

Correction of background noise in direct digital dental radiography.
Dentomaxillofacial Radiology, 1996To clarify the source of noise in direct digital intra-oral radiography with RVG-S (Trophy Radiologie, Vincennes, France) and to use these to develop a method for correction of background noise.Sensor temperature, image acquisition time and X-ray dose were independently analysed with the IPLab Spectrum (Signal Analytics, Vienna, VA) software.The ...

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 ...

Real-time sensing of tooth position for dental digital subtraction radiography
IEEE Transactions on Biomedical Engineering, 1991Dental digital subtraction radiography requires accurate repositioning of the patient and X-ray source in order to facilitate correct diagnostic of bone loss. Present mechanical repositioning systems do not allow radiography of posterior teeth, and are uncomfortable for the patient.

Dental digital radiography: a survey of quality aspects.
Swedish dental journal, 2005The aim was to evaluate the experiences of Swedish general dental practitioners (GDPs) with digital radiography and their opinion on the same, particularly regarding quality issues. A letter was sent to all GDPs in private care in Region Skåne, Sweden, asking whether they used digital radiography (n=513). The response rate was 79%.
