Tooth root abscesses in llamas and alpacas: 123 cases (1994-2005).
OBJECTIVE
To determine features, outcome, and complications of surgical treatment of camelid tooth root abscesses.


METHODS
Retrospective case series.


METHODS
123 camelids with tooth root abscesses.


METHODS
Signalment, history, teeth involved, surgery performed, ancillary diagnostic tests, and short-term complications were recorded from each medical record. An owner questionnaire was used to obtain long-term (> 1 year) follow-up information.


RESULTS
The most common surgical treatments included tooth extraction (n = 106) and apicoectomy (13). Owners provided follow-up information on 84 animals. Postoperative complications were reported in 42 of 84 animals. The most common complications included reinfection (n = 15), chronic draining tract (14), and osteomyelitis (14). Significantly more camelids that were in good or obese body condition at the time of surgery were alive at the time of follow-up, compared with those with thin body condition at the time of surgery. Camelids with 2 teeth extracted had significantly more complications than those with 1 tooth extracted. Thirty-four of 47 owners reported that they were completely satisfied with the outcome.


CONCLUSIONS
Owners of camelids in poor body condition should be forewarned that such animals are at greater risk for complications following dental surgery. Clinicians should recognize that the number of teeth affected was not associated with a poorer outcome.
