External Cervical Resorption: A Comparison of the Diagnostic Efficacy Using 2 Different Cone-beam Computed Tomographic Units and Periapical Radiographs
The aim of this study was to compare the diagnostic efficacy of 2 cone-beam computed tomographic (CBCT) units with parallax periapical radiographs for the detection and classification of simulated external cervical resorption (ECR) lesions. This study revealed that both CBCT scanners tested were equally accurate in diagnosing ECR and significantly better than periapical radiography. CBCT scans were more likely to correctly categorize ECR according to the Heithersay classification compared with parallax periapical radiographs
