Importance of 3D imaging in the evaluation of root formation following regenerative endodontic procedures: a case series

The follow-up of teeth that have undergone regenerative endodontic procedures through radiographic imaging is crucial for evaluating their success and determining their future prognosis. The periapical radiographs stand out as the primary tool for this task and are also recommended by the existing guidelines. However, two-dimensional (2D) imaging may not reveal the findings accurately, mimicking the root formation success which may not be true otherwise when assessed using cone beam CT (CBCT) imaging. This case series featuring two instances underscores the significance of CBCT in identifying such signs of failure, particularly when they might be obscured in 2D imaging.
