Effect of monitors on approximal caries detection in digital radiographs—standard versus precalibrated DICOM part 14 displays: An in vitro study

Effect of Varying Displays and Room Illuminance on Caries Diagnostic Accuracy in Digital Dental Radiographs

“…In earlier studies, lower illuminance levels were found to significantly improve diagnostic accuracy in the detection of caries lesions [Hellén-Halme et al, 2009] and wrist fractures [Brennan et al, 2007]. Consequently, recommendations have been issued [Samei et al, 2005;STUK, 2008] advocating appropriately low illuminance levels while evaluating radiographs.…”

Effect of ambient light level at the monitor surface on digital radiographic evaluation of approximal carious lesions: anin vitrostudy

“…A carious lesion in the enamel is a diagnostic challenge for dentists. Many studies 2,3,7,18 have concluded that both intra-and interobserver agreement for carious lesions in the enamel is low. It was also concluded 2,3,7,18 that despite many efforts to optimize the technical settings in dental digital radiography, it was still difficult to obtain good results of the diagnostic accuracy for enamel lesions.…”

“…[1][2][3] Previous studies investigated digital detectors and concluded that they were neither better nor worse than analogue film. [4][5][6] One study 7 evaluated various types of monitors and found that, when specifically adjusted for the task of detecting carious lesions on radiographs, standard liquid crystal display (LCD) colour monitors are as good as more sophisticated monitors specifically designed for digital radiographic evaluation.…”

DICOM part 14: GSDF-calibrated medical grade monitorvsa DICOM part 14: GSDF-calibrated “commercial off-the-shelf” (COTS) monitor for viewing 8-bit dental images

“…A recent dental study found that DICOM part 14: GSDF-calibrated display devices made no significant difference to the accuracy of approximal caries lesion diagnosis. 18 However, many dental practitioners may be unaware of the ability to apply window levelling to the displayed images in order that all greyscales present in the input image can be visualized sequentially in time by mapping part of the input greyscales to the available grey levels of the display, and window levelling will invariably increase the time needed to analyse a displayed image. There is more of a dependence on the actual monitor to just present the captured digital information itself during the interpretation and review of the displayed image, and very often the specifications and quality of the monitor can be overlooked by the end user.…”
