Role of cone beam computed tomography and white mineral trioxide aggregate in the successful management of a permanent anterior tooth with open apex.

Cone beam computed tomography (CBCT) is a recent three-dimensional (3D) radiographic imaging modality used for the accurate diagnosis, management and follow-up of endodontic problems. In tooth with open apex and periapical lesion, the use of new obturation material such as white mineral trioxide aggregate (wMTA) facilitates faster and more predictable closure of root apex and periapical healing. The objective of this case report was to evaluate the role of CBCT and wMTA obturation in management of a permanent anterior tooth with open apex and periapical lesion. After CBCT evaluation of maxillary left central incisor with open apex and periapical lesion, it was endodontically treated with wMTA obturation. The patient was recalled regularly for 6 months. CBCT was found to be a useful tool for the diagnosis and post-operative evaluation of this case. The wMTA used for obturation in two visit endodontic treatment resulted in successful outcome, both clinically and radiographically.
