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.

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.

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 ...

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.

Digital radiography-A cutting edge in the dental practice: A survey
Indian Journal of Contemporary Dentistry, 2014Objective : To compare radiographic technique used by general dental practices i.e. comparison between the use of digital radiography and conventional radiography&to determine the reasons for any difference in numbers. Method : A survey was conducted to study the use of conventional and digital radiographic techniques among 200 general dental ...

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.

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.
