Analysis of interpretations of full-mouth and panoramic surveys

The purposes of this study were to determine differences in interpretation of radiographic findings of full-mouth and panoramic surveys by junior and senior dental students and differences in their interpretive skills. The parameters of interest were caries, incipiencies, lamina dura interruptions, periodontal membrane changes, and periapical bone changes. The questions to be answered regarding the differences between the full-mouth and panoramic surveys were: (1) In which type of radiograph were the most lesions found? (2) In which type of radiograph are the most "non-existing" lesions found? (3) In which type of radiograph are the most lesions undetected? (4) Does the junior or senior dental student demonstrate the most accuracy in his interpretation?
