This study investigated the effect of different monitor calibration modes under various ambient lighting conditions on the ability of observers to recognize proximal carious lesions of varying depths.
7 observers evaluated 100 teeth for proximal carious lesions on standardized digital radiographs using 3 set-ups: (1) pre-calibrated monitor for high ambient light (higher than 1000 lux), (2) pre-calibrated monitor for low ambient light (less than 50 lux) and (3) Barten calibration (Digital Imaging and Communication in Medicine) on the monitor in dimmed ambient light (less than 50 lux). Receiver operating characteristic curves were plotted for all observations. The criterion standard was histological examination of the teeth. The effects of three conditions were compared using a paired t-test. The level of significance was set to p < 0.05.
No significant difference was found 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.
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.
本研究旨在探讨不同环境光照条件下不同显示器校准模式对观察者识别不同深度近表面龋损能力的影响。
7 名观察者使用 3 种设置（1）高环境光（高于 1000 勒克斯）下预校准的显示器，（2）低环境光（低于 50 勒克斯）下预校准的显示器和（3）在环境光低于 50 勒克斯时的监视器上的 Barten 校准（数字成像和通信医学），对标准化数字射线照片上的 100 颗牙齿进行近表面龋损评估。为所有观察结果绘制受试者工作特征曲线。牙齿的标准诊断标准是组织学检查。使用配对 t 检验比较三种条件的影响。显著性水平设置为 p < 0.05。
根据不同的环境光照水平，不同的显示器校准模式对任何类型的近表面龋损的检测准确性均无显著差异。
只要显示器按照周围光照水平进行校准，环境光照水平的差异不会影响对数字射线照片中龋损的检测能力。
