To evaluate the diagnostic accuracy of caries and periapical lesions on a monitor with and without DICOM part 14: grayscale standard display function (DICOM-GSDF) calibration under different ambient light conditions. Forty digital bitewing radiographs were selected, with or without radiographic images of carious lesions and forty digital periapical radiographs with or without periapical lesions were selected from archives of the Radiology Department at the University Hospital of the Federal University of Sergipe. The gold standard radiographic images were determined through consensus between two radiologists with more than 15 and 30 years of experience. The selected radiographs were evaluated on a LG LED monitor with and without DICOM-GSDF calibration under different ambient light conditions: Lx1 (low ambient lighting), Lx2 (moderate ambient lighting) and Lx3 (high ambient lighting). Kappa (K) values determined that evaluator 1 showed almost perfect agreement for all devices, while evaluator 2 presented a substantial agreement for all devices. Monitors with and without DICOM-GSDF calibration have similar accuracy values. The three ambient light conditions analyzed have similar accuracy and can be used for caries lesions diagnosis (p > 0.05); however, the best diagnostic accuracy of periapical lesions was found in Lx 2. The displays with and without DICOM-GSDF calibration studied in this research have similar accuracy and can be used to evaluate digital radiographs without changing the diagnostic capacity. The different ambient lighting conditions did not influence the evaluation of caries lesions. The best diagnostic accuracy of periapical lesions was found in moderate ambient lighting.
评估在不同环境光条件下使用和不使用 DICOM 第 14 部分：灰度标准显示功能 (DICOM-GSDF) 校准的监视器上龋病和根尖周病变的诊断准确性。从塞尔希培联邦大学医院放射科的档案中选择了 40 张数字化咬合片，有无龋病放射影像，以及 40 张数字化根尖周片，有无根尖周病变。金标准放射影像通过两位具有 15 年以上和 30 年以上经验的放射科医生的共识来确定。在不同的环境光条件下：Lx1（低环境照明）、Lx2（中等环境照明）和 Lx3（高环境照明），在具有和不具有 DICOM-GSDF 校准的 LG LED 监视器上评估所选的射线照片。Kappa（K）值确定评估者 1 对所有设备都显示出几乎完美的一致性，而评估者 2 对所有设备都显示出实质性的一致性。具有和不具有 DICOM-GSDF 校准的监视器具有相似的准确性值。分析的三种环境光条件具有相似的准确性，可用于龋病病变的诊断（p>0.05）；然而，根尖周病变的最佳诊断准确性是在 Lx2 中发现的。在本研究中研究的具有和不具有 DICOM-GSDF 校准的显示器具有相似的准确性，可以在不改变诊断能力的情况下用于评估数字射线照片。不同的环境照明条件不会影响龋病病变的评估。根尖周病变的最佳诊断准确性是在中等环境照明中发现的。
