Digital versus conventional radiography for determination of primary incisor length
(2009-04-01)
Aim: This in vitro study evaluated the accuracy of primary incisor lengths determined by digital and conventional radiography compared to the actual tooth length. Methods: Twenty extracted primary maxillary incisors were ...
Comparative analysis of human and bovine teeth: Radiographic density
(2008-12-01)
Since bovine teeth have been used as substitutes for human teeth in in vitro dental studies, the aim of this study was to compare the radiographic density of bovine teeth with that of human teeth to evaluate their usability ...
Accuracy of direct digital radiography for detecting occlusal caries in primary teeth compared with conventional radiography and visual inspection: an in vitro study
(BRITISH INST RADIOLOGY, 2010)
Objectives: The diagnosis of caries lesions is still a matter of concern in dentistry. The diagnosis of dental caries by digital radiography has a number of advantages over conventional radiography; however, this method ...
Bone mineral density on conventional and digitized images under different parameters of digitization and storage
(2010-10-21)
Aim: To assess the bone mineral density on conventional and digitized images, comparing whether different parameters of digitization and storage change these values. Methods: Twenty radiographs were taken from five partially ...
Accuracy of linear measurements before and after digitizing periapical and panoramic radiography images
(Fundação Odontológica de Ribeirão Preto, 2011)
The aim of this study was to evaluate the accuracy of linear measurements made on conventional and digitized periapical and panoramic radiographic images of dry human hemi-mandibles. Images from the posterior region of 22 ...

Comparison of changes in dental and bone radiographic densities in the presence of different soft-tissue simulators using pixel intensity and digital subtraction analyses
(British Inst Radiology, 2013-09-01)
Objectives: To evaluate the influence of soft-tissue simulation materials on dental and bone tissue radiographic densities using pixel intensity (PI) and digital subtraction radiography (DSR) analyses.Methods: 15 dry human ...
Assessment of manipulation accuracy of digitized occlusal radiographic images--sub and over exposure.
(2009-12-01)
The aim of this study was to evaluate whether digitized images obtained from occlusal radiographs taken with low or over dose of radiation could be improved with the aid of computer software for digital treatment. Thirteen ...
Evaluation of the maxillary premolar roots dissociation using radiographic holders with conventional and digital radiography
(Sociedade Brasileira de Pesquisa Odontológica, 2010)
This in vivo study evaluated the dissociation quality of maxillary premolar roots combining variations of vertical and horizontal angulations by using X-ray holders (Rinn -XCP), and made a comparison between two types of ...
Detection of cavitated approximal surfaces using cone beam CT and intraoral receptors
(2013-01-01)
Objectives: The aim of this study was to compare cone beam CT (CBCT) in a small field of view (FOV) with a solid-state sensor and a photostimulable phosphor plate system for detection of cavitated approximal surfaces. ...
