چکیده

Background and aims. early diagnosis of external root resorption is important for accurate treatment. the purpose of this study was to compare the efficacy of a charge-coupled device (ccd) sensor and a photostimulable phosphor (psp) plate receptor in the diagnosis of artificial external root resorption. materials and methods. in this diagnostic in-vitro study, 40 maxillary incisors were mounted in a segment of dry bone and preliminary radiographs were obtained using ccd and psp sensors. artificial resorption cavities were produced on the middle-third in half of the samples and on the cervical-third in the other half on the buccal root surfaces. radiographs were repeated and images were evaluated. data were statistically analyzed using chi-square and diagnostic tests. results. there were no significant differences between the two sensors in the sensitivity (p=0.08 and 0.06) and specificity (p=0.13) for the diagnosis of resorption in both root areas. the overall accuracy of ccd was higher than psp sensor; however, the difference was not statistically significance (p>0.05). conclusion. ccd and psp sensors chosen for the present study produced similar results in diagnosing simulated external root resorption.
