Between 2002 and 2005 210 rabbits, 257 guinea pigs and 123 chinchillas were examined; oral disease was diagnosed in 38·1 per cent of the rabbits, 23·4 per cent of the guinea pigs and 32·5 per cent of the chinchillas. In the rabbits, the maxillary right P3, mandibular right P3, P4 and M1 and mandibular left P3, P4, and M1 were the teeth most frequently affected; in the guinea pigs, the mandibular right P4 and both the mandibular left incisor and P4 were most often affected; and in the chinchillas the maxillary right P4 and M1 and maxillary left P4 were most often affected. The incisors and first mandibular cheek teeth of the guinea pigs were significantly more often affected than those in the chinchillas or rabbits. Bilateral lesions of the maxillary cheek teeth were significantly more common in the chinchillas. The highest incidence of gingival hyperplasia was recorded in the rabbits. The incidence of gingival erosions and gingivitis were significantly higher in the chinchillas.
