Use of videofluoroscopy in zoo dentistry: endodontic procedure in a tiger.

Videofluoroscopy was used as a radiographic technique to visualize a canine tooth during root canal therapy in a Siberian tiger. Videofluoroscopy was useful because the procedure was performed in a zoo setting with no access to an on-site darkroom. The fluoroscopic screen and videotape allowed for immediate viewing of the root canal system.
