The topographical anatomical studies of the teeth were carried out on 20 skulls of donkeys ranging in age between 5-20 years and 10 skulls of horses aging from 5-20 years. In 4 cases of donkeys and one case of horses a rudimentary upper 1P (wolf tooth, was found in upper jaw, which is short, narrow, smooth and lighter in colour. At age of 5-6 years in donkeys and horses we found that the cheek teeth have a long crown (hypodont type), the part of the crown embeded in the alveoli is known as the reserve crown. It was found that the lateral root of 4P and all roots of 1M are embeded in the inferior maxillary sinus, but in horses all roots of 4P and 1M are embeded in the inferior maxillary sinus. While the roots of 2M and 3M are embeded in the superior maxillary sinus in donkeys and horses.
Some dental affections were recorded from 49 skulls of donkeys and horses and also from 9 clinical cases. These affections were classified according to their incidence, dental caris, sharp enamel points, projection of 2P upper cheek teeth, dental tartar (calculus), diastasis dentium, fracture of the teeth, polydentia, exuberantia dentis, all these cases must be treated as early as possible to avoid more complications. Another recorded cases were diastasis dentium, stepformed table mouth and oligodentia.
