Abstract
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 SPP 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 Dürr 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 Az value for the radiographs scanned with the Dürr 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.
