Forty-five skulls of European brown bears from the Central Forest Nature Reserve and adjacent regions were examined in detail. The frequencies of oligodonty, dental caries, parodontosis, and traumatized teeth were estimated. A total of 12 variants of the tooth formula were described. The sample under study was distinguished from the populations examined previously by the lowest frequency of oligodonty. Dental caries in one or several teeth, caused by mechanical damage or malocclusion, occurred in 14% of animals. Strong wear marks on the canines caused by feeding on oats frequently resulted in broken canines in bears of the senior age groups. [ABSTRACT FROM AUTHOR] |
