Endodontic clinical management of a dens invaginatus case by using a unique treatment approach: A case report

摘要

Introduction: Dens invaginatus is a developmental anomaly that poses treatment challenges when nonsurgical root canal therapy is deemed necessary. Teeth with complex root canal morphology often require a comprehensive treatment approach to effectively clean, shape, and disinfect the pulp canal space before obturation. Endodontic clinical management of a tooth with dens invaginatus might include using cone-beam computed tomography (CBCT) to aid in the diagnosis and treatment-planning phase and use of the surgical operating microscope in performing the clinical phase of treatment. A novel approach could include using the revascularization technique as the final treatment step in the management of a dens invaginatus case in which the root apex has not completed formation. Methods: This case report will provide both an overview of the feasibility of using CBCT scans in diagnosis and treatment planning and a step-by-step clinical technique, by using surgical operating microscope and the revascularization technique, in the successful endodontic management of a complex dens invaginatus case. Conclusions: Five-month and 12-month follow-up clinical and radiographic findings will provide a candid view of inherent advantages and challenges of this technique.
