Dental Health Status and Endodontic Treatment of Captive Brown Bears ( Ursus Arctos ssp.) Living in the Bernese Bear Pit
The teeth of five adult captive brown bears (Ursus arctos ssp.) were examined and radiographed for occlusion, loss of teeth, dental plaque and calculus, and attrition under general anesthesia. Deposits of dental calculus were found in various locations with an overall prevalence of 8% to 15% of all...
