Carious lesions: diagnostic accuracy using pre-calibrated monitor in various ambient light levels: anin vitrostudy

Abstract

There is no evidence that any difference between ambient light levels affects the ability to detect carious lesions in digital radiographs as long as the monitor was calibrated in accordance with the surrounding light level.

Performance of 5 different displays in the detection of artificial incipient and recurrent caries-like lesions

“…The interval window length is longer than the more commonly reported two weeks, however it is approximately half that of some other studies which reviewed images after at least six months. 2,17,18 In two studies by Hellén-Halme et al 19,20 they reported intraobserver agreement ranging from fair to moderate, which was similar to our restored molar agreement. 19,20 However our intraobserver agreement was significantly higher than Hellén-Halme et al 19,20 for the primary caries detection on the premolar, which was observed to be from moderate to almost perfect.…”

Although Hellén-Halme et al 19,20 did not themselves find statistically significant differences, perhaps the variation in light levels led to more uncertainty by the observers and therefore lower agreements (fair to good) when evaluating primary caries.…”

Diagnostic accuracy of different display types in detection of recurrent caries under restorations by using CBCT

“…25,26 Authors claimed that the ability to detect carious lesions by experienced clinicians can be enhanced by hooding laptop displays in bright clinical environments. 25 In a previous study, 26 seven observers evaluated teeth for proximal carious lesions on standardized intraoral digital radiographs using three setups as follows: (1) precalibrated monitor for high ambient light (.1000 lux), (2) precalibrated monitor for low ambient light (,50 lux) and (3) Barten calibration (digital imaging and communication in medicine) on the monitor in dimmed ambient light (,50 lux). Authors found no difference in diagnostic accuracy for the detection of any type of proximal carious lesions between the different calibration modes of the monitor according to different ambient light levels.…”

“…Authors concluded that monitor calibration according to ambient light level eliminates the negative effects of ambient light in detection of carious lesions in digital radiographs. 26 In the present study, ambient light was not an issue, as we assessed all types of images under dimmed light and no calibration was applied to display modes prior to viewing sessions.…”
