CHAPTER 2 Intraoral Radiographic Anatomy of the Dog
MAXILLARY INCISOR TEETH


FIGURE 2-2 Normal incisor teeth. A, Radiograph of the incisor teeth and rostral maxillary region of a young adult dog. B, Dorsal view of prepared skull. C, Palatal (mirror) view of skull. D, Same radiograph as A. The crowns of the incisor teeth are foreshortened due to a projection angle that makes an image of the roots without elongation artifact (see Chapter 12).
CANINE TEETH

MAXILLARY PREMOLAR TEETH


FIGURE 2-23 Normal maxillary premolar teeth The facial and palatal region of the dog consists of 36 bones designed to provide a large surface area for the sense of smell and to hold the teeth. The premolar teeth are all within the alveolar process of the maxilla. However, radiographs of the premolar teeth may project through the nasal, frontal, palatine, and zygomatic bones. A, Radiograph of the left maxillary premolar region of a young dog. B, Buccal (vestibular) view of prepared skull. C, Nasal surface of maxilla. D, Same radiograph as A. Correct use of the bisecting angle technique makes an image with accurate root length. The apical anatomy, however, will be slightly enlarged due to an increased object-to-film distance at the apex.
