Endodontic Retreatment of a Maxillary Central Incisor with a Wide Apex and Short Root
Overview:
In this video, Luca discusses a complex retreatment case involving an upper right central incisor with challenging anatomy. He focuses on isolation strategies for conical teeth, techniques for removing old root filling material, and the use of Mineral Trioxide Aggregate (MTA) plugs for wide apices.
The Case & History:
An asymptomatic patient presented for endodontic retreatment of the maxillary right central incisor. Radiographic examination revealed a significantly shortened root with an irregular, wide apex. The tooth had been previously treated, and the clinical history suggested that previous orthodontic movement or trauma may have contributed to the apical resorption and the unusually wide canal morphology.
The Clinical Problem:
The clinician encountered difficulties in achieving stable rubber dam isolation due to the conical shape of the clinical crown and the lack of natural undercuts. Furthermore, the case presented challenges in the thorough removal of previous root filling material and the selection of an appropriate obturation technique for a wide, non-tapered apex.
