20 Clinical lesions and signs of discomfort
The cat had no previous history of oral or dental disease. She had been presented to the referring veterinarian due to signs of oral discomfort, i.e. reduced appetite and selecting soft foods. On conscious clinical examination, the referring veterinarian had identified cavities at the buccal aspects of several teeth and referred the cat to us for evaluation and treatment.
The following teeth were affected by external root resorption: 304 (Fig. 20.2b), 307 (Fig. 20.1b), 404 (Fig. 20.2b), 104 (Fig. 20.5), 107 and 204 (Fig. 20.3b).
Figure 20.5 Oblique lateral radiograph of the right rostral upper jaw. Replacement resorption of 104 is obvious. Note the radiolucent resorption tracks within the dentine of the root. Tooth 106 was missing on clinical examination and the radiograph shows that it is resorbing.
