Evaluating the Diagnostic Superiority of CBCT Over Conventional Radiography in Complex Endodontic Cases: A Quantitative Analysis

Abstract

The accuracy of diagnostic imaging plays a pivotal role in the success of endodontic treatment, especially in complex cases involving intricate root canal anatomy, hidden fractures, and periapical lesions. This study quantitatively evaluates the diagnostic superiority of Cone-Beam Computed Tomography (CBCT) over conventional periapical radiography in identifying complex endodontic conditions. A total of selected clinical cases with varying endodontic complexities were analyzed using both imaging modalities. Diagnostic parameters such as sensitivity, specificity, and overall accuracy were statistically compared. The findings revealed that CBCT demonstrated significantly higher diagnostic precision, particularly in detecting missed canals, root fractures, and periapical pathologies that were not clearly visible on traditional radiographs. Although CBCT involves higher radiation exposure and cost, its three-dimensional visualization offers substantial benefits in improving diagnostic outcomes and treatment planning. The study concludes that CBCT should be considered a superior diagnostic tool in complex endodontic cases where conventional radiography proves inadequate.
