<scp>2D</scp> versus <scp>3D</scp> radiographic assessment of asymptomatic persistent endodontic lesions

Overall, CBCT provided a more comprehensive examination of teeth with APEL than PA radiographs. Larger lesion sizes were generally observed, especially in posterior teeth. Sinus involvement was more readily identified, and the assessment of the presence of missed canals could be performed with more certainty. Where lesion monitoring is chosen, CBCT imaging should be considered for a more thorough assessment of posterior teeth, and where there is uncertainty in PA radiograph interpretation of anterior teeth.
