Comparative analysis of the accuracy of periapical radiography and cone‐beam computed tomography for diagnosing complex endodontic pathoses using a gold standard reference – A prospective clinical study

Abstract

Overall, CBCT had a higher diagnostic accuracy in complex endodontic pathoses compared to PR. Nevertheless, CBCT failed to diagnose apicomarginal bone defects in 33% teeth. In evaluating the status of buccal cortical plate from CBCT images, observers could detect absence of bone better than its presence. Thus, limited FOV CBCT should be considered for selective cases where periapical radiography has diagnostic ambiguity.
