Single Rooted Permanent Premolars and Molars - A Rare Clinical Presentation Confirmed using Cone Beam Computed Tomography.

The morphology of the root and root canal system plays a significant role in the treatment outcome of endodontic procedures. The necessity of clear and high contrast images for tissues like bone and teeth has made the usage of newer imaging techniques inevitable. This is a rare case report wherein, the permanent posterior dentition of both arches was single rooted. While sporadic cases of single rooted teeth have been reported, it is rare for all the premolars and molars to show such variation. This rare clinical observation has been enhanced by Cone Beam Computed Tomography (CBCT), which provides a clear image with added benefits of 3D (Three Dimensional) image reconstruction, low dosage and rapid scan time.
