FIGURE 3-1 Normal incisor teeth in adult cat. A, Radiograph of the incisor teeth and rostral maxillary region of an adult cat skull. B, Dorsal view of prepared skull. D, Same radiograph as A.

FIGURE 3-2 Normal incisor teeth in adult cat. Superimposition of the nasal ridge of the incisive bone over the incisor roots has been shifted apically (compared to Figure 3.3.1) by angulation of the x-ray beam (ventral tube shift) to elongate the incisor roots. A, Radiograph of incisors in adult cat skull. B, Dorsal view of prepared skull

FIGURE 3-3 The maxillary third incisor tooth and interalveolar bone (between third incisor and canine) can be better imaged using a more lateral projection angle. A, (facing page) Radiograph of adult cat skull. B, (facing page) Labial view of prepared cat skull. C, Saggital plane from CT image of cat skull at level of maxillary third incisor. Area of hypoattenuation in the periapical area (arrow) corresponds to area of decreased bone density around the root tip of the maxillary third incisor. D, Same radiograph as in A.

FIGURE 3-4 Radiographs demonstrating dental problems. A, Periodontal disease (periodontitis) with associated alveolar bone loss (arrows). B, Radiograph of rostral maxilla revealing six retained roots (arrows) from a cat “missing” all the incisors.

FIGURE 3-5 Normal adult cat canine teeth. A, Radiograph of the skull of an adult cat showing the canine teeth and surrounding structures. B, Dorsal view of prepared skull. C, Ventral (mirror) view of skull. D, Same radiograph as A.

FIGURE 3-6 Normal adult cat canine tooth. A, Radiograph of the maxillary right canine tooth. B, Palatal view of prepared skull specimen. C, Radiograph illustrating the nasal surface of the alveolar process of the maxilla. Holes were drilled into the nasal surface of the maxilla bone where the nasal and palatal portions meet and these were filled with gutta percha. D, CT scan, transverse plane at mid-root of canine teeth (arrows). E, Same radiograph as in A.

FIGURE 3-7 A, Radiograph of the right canine tooth and surrounding structures in an adult cat. B, Labial view of prepared specimen. C, Same radiograph as in A.

FIGURE 3-8 Radiographs of feline canine teeth demonstrating commonly found abnormalities. A, Radiograph of the left maxillary canine tooth in an adult cat demonstrating severe alveolar (attachment) bone loss (open arrow) and external root resorption (arrow) associated with severe periodontitis. B, Radiograph of right maxillary canine revealing loss of apical lamina dura (arrow) (endodontic disease, see Chapter 6) and alveolar bone loss (open arrow) (periodontitis, see Chapter 5). C, Radiograph of maxillary right canine revealing severe root resorption (arrow) typically seen with tooth resorption in feline canine teeth (see Chapter 7).

FIGURE 3-9 Normal maxillary premolar and molar teeth in the adult cat. The premolar and molar teeth are all within the alveolar process of the maxilla. Radiographs of the maxillary premolar and molar teeth in cats often projects through the zygomatic bone. A
