UNASSIGNED: 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.
UNASSIGNED: 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).
UNASSIGNED: 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.
■这项研究是一项横断面分析,临床研究。对健康的5至8岁儿童的初级磨牙的近端表面进行了影像学检查,以检查牙釉质或牙本质的外三分之一(D1)是否存在龋齿病变。两名经过培训和校准的检查者评估了咬痕X射线照片和DIAGNOcam图像中的龋齿深度,然后在临时牙齿分离后使用“国际龋齿检测和评估系统”通过直接视觉检查验证了空化的存在。
■本研究共纳入了236个近端病变。大多数临床上的空化病变(51.9%)是影像学上的D1,并且在DIAGNOcam的外部牙本质病变(评分3和4)中(分别为37%和48.1%,分别)。尽管DIAGNOcam显示出更高的灵敏度(0.852)与X射线照片(0.519)相比,与X线照片(0.579)相比,其特异性(0.569)略低.然而,与射线照相方法(AUC=0.561;P=0.308)相比,DIAGNOcam显示出更高的曲线下面积值(AUC=0.722;P<0.001)。
■在诊断原发性磨牙的近端空化病变方面,DIAGNOcam比bitewingX光片显示出更高的灵敏度和更好的准确性,通常可以被认为是X光片的替代方法,以检测空化,而不会对儿童造成电离辐射的危害。
