A digital subtraction technique for dental radiography

Oral Surgery, Oral Medicine, Oral Pathology, 1983
The 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.

Is digital better in dental radiography?

Radiation Protection Dosimetry, 2008
In 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.

Digital Radiography in the Dental Practice: An Update

Primary Dental Journal, 2013
The 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.

Quantitative subtraction with direct digital dental radiography.

Dentomaxillofacial Radiology, 1997
To 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, 2000
The 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.

Digital radiography in general dental practice: a field study

Dentomaxillofacial Radiology, 2007
The aim of this study was to conduct a field study to survey the performance of digital radiography and how it was used by dentists in general dental practice.19 general dental practitioners were visited at their clinics. Ambient light (illuminance) was measured in the rooms where the monitors were placed.

Quality assurance tests for digital radiography in general dental practice

Dental Update, 2014
Quality 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.
