ABSTRACT
Objective:
the aim of this study was to compare the diagnostic accuracy of two direct digital radiography systems the charge-coupled device (CCD) XIOS XG Sirona and the photostimulable storage phosphor (PSP) VistaScan DürrDental, in the detection of non-cavitated proximal caries lesions. materials andmethods:
in this experimental and cross-sectional study 112 proximal surfaces from 27 molars and 31 premolars with or without proximal caries lesions were evaluated and randomly allocated in a study unit. bitewing radiographs were acquired with a CCD XIOS XG and with the PSP VistaScan. a single x-ray unit was used for both systems. radiographic images were assessed independently by two calibrated radiologists. histological evaluation on a stereomicroscope was used as gold standard.results:
sensitivity values were found to be 0.35 for CCD and 0.31 for PSP. specificity values were found to be similar for both systems (0.867). az values showed a low diagnostic accuracy for both sensors 0.61 for CCD and 0.59 for PSP, no statistical difference was found between these two values (p=0.78).conclusion:
both digital radiology systems have a high diagnostic accuracy to detect sound surfaces but low diagnostic accuracy to detect proximal carious lesions.
