To evaluate the diagnostic abilities of near-infrared light transillumination (using the DIAGNOcam) and bitewing radiographs in detecting cavitated proximal carious lesions in primary molars.
The study was a cross-sectional analytical, clinical study. The proximal surfaces of primary molars of healthy 5- to 8-year-old children were radiographically screened for the presence of carious lesions in the enamel or outer third of dentin (D1). Two trained and calibrated examiners evaluated the depth of caries in bitewing radiographs and DIAGNOcam images and then verified the presence of cavitation by direct visual examination using the "International Caries Detection and Assessment System" after temporary tooth separation.
A total of 236 proximal lesions were included in the study. Most of the clinically cavitated lesions (51.9%) were D1 radiographically and in outer dentin lesions (scores 3 and 4) by the DIAGNOcam (37% and 48.1%, respectively). Although DIAGNOcam showed higher sensitivity (0.852) compared to the radiographs (0.519), it showed slightly less specificity (0.569) compared to the radiographs (0.579). However, DIAGNOcam showed higher value of the area under the curve (AUC = 0.722; P < 0.001) compared to the radiographic method (AUC = 0.561; P = 0.308).
The DIAGNOcam showed higher sensitivity and better accuracy than bitewing radiographs in diagnosing cavitated proximal lesions in primary molars and can be generally considered as an alternative to radiographs to detect cavitation without the hazards of ionizing radiation in children.
评估近红外光透照法（使用DIAGNOcam）和咬合翼片X线片在检测乳牙邻面龋损龋洞方面的诊断能力。
本研究为横断面分析性临床研究。对5至8岁健康儿童乳牙的邻面进行X线片筛查，以确定釉质或牙本质外三分之一（D1）中是否存在龋损。两名经过培训和校准的检查者评估咬合翼片X线片和DIAGNOcam图像中的龋损深度，然后在乳牙分离后使用“国际龋病检测与评估系统”通过直接视觉检查来确认龋洞的存在。
本研究共纳入236个邻面病变。大多数临床有龋洞的病变在X线片上为D1，而DIAGNOcam检测到的外牙本质病变（评分3和4）分别为37%和48.1%。尽管DIAGNOcam的灵敏度（0.852）高于X线片（0.519），但其特异性（0.569）略低于X线片（0.579）。然而，与X线片检查方法相比，DIAGNOcam的曲线下面积值更高（AUC = 0.722；P < 0.001），X线片检查方法的AUC = 0.561；P = 0.308。
在诊断乳牙邻面龋洞病变方面，DIAGNOcam比咬合翼片X线片具有更高的灵敏度和更好的准确性，并且通常可被视为一种替代X线片的方法，用于检测龋洞，而不会给儿童带来电离辐射危害。
