Iceboy, a 13-year-old white tiger was presented with multiple tooth fractures, including complicated crown-root fractures (with pulp exposure) in all four canine teeth. Diagnostic workup included full-mouth radiography, dental charting and probing. The patient was operated on by a dental team of four (including two european specialists in veterinary dentistry) in Sóstó Zoo (Nyíregyháza, Hungary). Anaesthesia team was provided by the zoo. All canine teeth were treated by root canal treatment including a combination of hand-filing and motorized techniques in a single anaesthetic episode. Simultaneous treatment of ipsilateral canine teeth in lateral recumbency was performed to reduce anaesthesia time.15 months later a follow-up procedure was performed, during which all previously treated teeth were radiographically rechecked and were considered successful. This presentation highlights the challenges of performing complex dental procedures in a zoo environment and reviews the current literature on endodontic treatment of large felids.
