ABSTRACT
Ahrari Khafi MS, Tabrizi AS., Dental
root elongation in a New Zealand white rabbit, Onl J Vet
Res., 19(12): 803-807, 2015. A 2 year old male New Zealand white rabbit with a
large mass in the ventral border of the left mandible was presented for
examination. Because the rabbit had been fed solely a soft diet, dental root
elongation was suspected and the patient was radiographed. Radiography showed
elongated roots of mandibular cheek teeth penetrating mandibular bone causing
osteomyelitis and abscess formation confirming grade 5 root elongation.
Due to a poor prognosis and limited treatment options, euthanasia was
recommended, but not done. The abscess was treated and patient discharged, but
1 month later, the rabbit was referred again with abscess reformation at the
previous site. Radiography revealed progressed root elongation and
osteomyelitis but in spite of the severe lesions, appetite and body condition
had not been affected. The abscess was evacuated and the patient was discharged
again. Bacterial culture showed that the mass exudates were sterile. Contrary
to previous reports (except for abscess formation), the patient did not suffer
from anorexia, drooling and epiphora and continued to
live for another 6 months. The finding suggests that euthanasia may not advised for every case of severe dental root elongation.
Key Words: dental root
elongation, rabbit, abscess.
