Abstract

Post-mortem examination of 19 donkey skulls showed that donkeys have a greater degree of anisognathia (27% width difference between upper and lower jaws) compared to horses (23%). Teeth (n = 108) were collected from 14 skulls and examined grossly and by computed axial tomography (CAT). A greater degree of peripheral enamel infolding was found in mandibular check teeth (CT) compared to maxillary CT (P <0.001). A significant increase in peripheral cementum from the apical region to the clinical crown was demonstrated in all CT (P <0.000 1). All donkey CT had at least five pulp cavities with six pulp cavities present in the 06s and I Is. A new endodontic numbering system for equid CT has been proposed. A greater occlusal depth. of secondary dentine (mm) was present in older donkeys (> 16 years) than in the younger (<15 years) donkeys studied. Based on gross and CAT examinations, donkey dental anatomy was shown to be largely similar to that described in horses. (c) 2008 Elsevier Ltd. All rights reserved.
