Management of Dens Invaginatus Diagnosed by Spiral Computed Tomography: A Case Report

A thorough knowledge of the normal anatomy of the root canal system as well as the possible aberrancies is imperative for success of endodontic therapy. The challenge lies in diagnosing these conditions properly, complete debridement of the root canal system, and 3-dimensional sealing of the same. Conventional diagnostic aids like radiographs play an important role in assessment of complex root canal morphologies. These modalities, however, do not provide detailed information of the complexity as a result of their inherent limitations. This calls for use of more advanced imaging modalities such as spiral computed tomography, which can help the clinician in making a more accurate diagnosis. This report discusses the usefulness of spiral computed tomography in accurate diagnosis of a case of dens invaginatus and its successful management.
