目的：为探讨存储式荧光板（SPP）X线片的扫描分辨率对邻面龋损检出的影响，采用15张SPP X线片，对10名口腔医师72颗前磨牙邻面龋损进行了评价，其理论空间分辨率分别为：（1）迪戈拉FMX，7.8 lp mm（-1）;（2）迪戈拉Optime，分别为7.8 lp mm（-1）和12.5 lp mm（-1）;（3）Durr VistaScan，分别为10 lp mm（-1）和20 lp mm（-1）。病变通过组织学检查进行验证。结果：Durr VistaScan在10 lp mm（-1）扫描的X线片的A（z）值显著低于其他系列X线片（P = 0.000）。结论：对于SPP X线片，理论空间分辨率本身的提高与邻面龋检测的改善无关。
Objectives: To investigate the effect of the scanning resolution of storage phosphor plate (SPP) radiographs on the detection of proximal caries lesions.Methods: 10 dentists evaluated 72 proximal surfaces of premolars with respect to caries from 15PP radiographs scanned with theoretical spatial resolutions of: (1) the Digora FMX at 7.8 lp mm(-1); (2) the Digora Optime at both 7.8 lp mm(-1) and 12.5 lp mm(-1); and (3) the Durr VistaScan at 10 lp mm(-1) and 20 lp mm(-1), respectively. The lesions were validated by histological examination. Receiver operating characteristic (ROC) analysis was employed.Results: The A(z) value for the radiographs scanned with the Durr VistaScan at 10 lp mm(-1) is significantly lower than those for the other series of radiographs (P = 0.000).Conclusions: For SPP radiographs, an increased theoretical spatial resolution per se is not related to an improved detection of proximal caries.
