Introduction: Precise diagnosis is essential for successful endodontic treatment. It is typically achieved based on patient’s first interview combined with physical examination and other complementary imaging examinations, including radiography. Endodontics is the dental specialty most often using diagnostic imaging techniques to obtain detailed information on teeth being assessed. Because of its two-dimensional nature, conventional radiographic images present limitations that hinder or make proper endodontic treatment planning impossible. Objective: The aim of this paper is to report a clinical case in which cone-beam computed tomography (CBCT) was key to endodontic diagnosis and treatment planning. Methods: Conventional periapical radiography revealed an image suggestive of external inflammatory root resorption of maxillary central incisor. Clinically, the tooth presented with chromatic alteration after having been subjected to trauma. CBCT examination was then requested for a more precise investigation. Results: The tomographic report of the investigated tooth highlighted no external inflammatory root resorption, but a distinct root anatomy characterized by intense root dilaceration. Endodontic treatment was deemed unnecessary, and veneering of the affected tooth, as well as periodic clinical and radiographic follow-up was recommended. Conclusion: The clinical case reported herein reveals the significance of CBCT imaging on treatment decisions in Endodontics.
