A modified technique for using the endoscope in periradicular surgery. A case report

The aim of this case report was to describe a modified endoscopic technique for enhancing visualization in endodontic microsurgery. Tooth treated surgically showed a periradicular lesion of strictly endodontic origin. Following the reflection of a full mucoperiosteal papilla base incision flap, surgical access to the root was made through the cortical bone. The periradicular lesion was curetted, root-end was resected, and root-end cavity was prepared with a zirconium nitrate tip driven by ultrasonic device unit. Finally zinc oxide EBA-reinforced cement root-end filling was placed. Root-end management procedure was performed using an endoscope. Diving the endoscope lens in the bone cavity filled with saline solution contributed to improve visualization and keep clear the lens. Following clinical and radiographic assessment at 12 months postsurgery, the case was evaluated successfully. Thus, in conclusion, the endoscope provided excellent visualization of the surgical field during root-end cavity preparation.
