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 ...

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.

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 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.

Reliability of digital radiography of interproximal dental caries.
American journal of dentistry, 2004To compare the effects of different image processing modes (filters) on the reproducibility and validity of the assessment of interproximal carious lesions viewed in digitized radiographic images.Variables studied were film type, exposure time, and tissue scatter radiation. Images were assessed in relation to film type, exposure time and tissue scatter.

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%.

Filmless imaging: the uses of digital radiography in dental practice.
Journal of the American Dental Association (1939), 2005As use of digital radiography becomes more common, many dentists are wondering if and how they can replace conventional film-based imaging with a digital system. This article briefly describes the different technologies used for digital radiography in dentistry.
