Dental and Temporomandibular Joint Pathology of the Grey Wolf (Canis lupus).
Skulls from 392 grey wolves (Canis lupus) were examined macroscopically according to predefined criteria. Two hundred and seven skulls were included in this study, comprised of 124 young adults (59.9%) and 83 adults (40.1%); of these, 65 (31.4%) specimens were from male wolves and 104 (50.3%) were f...

Out of 8,694 possible teeth, 8,339 (95.9%) were present for evaluation.

One hundred and sixty-one skulls (77.8%) showed signs of endodontal disease, including attrition or abrasion on 144 skulls (69.6%) and 2,522 teeth (30.2%)and 424 fractured teeth (5.1%) on 103 skulls (49.8%).
