Dental Treatment in Three Red-necked Wallabies (Macropus Rufogriseus)– A Case Series

The red-necked wallaby or Bennett’s wallaby (Macropus rufogriseus) is a medium-sized macropod marsupial (wallaby), which inhabits the coastal forests of eastern and southeastern Australia and Tasmania. They have been trapped extensively for fur and persecuted by ranchers. However, the population numbers have recovered in recent years and they are now common to abundant throughout most parts of their range. Three intact, red-necked wallaby females, all aged 6 years, from the local zoo were presented with a history of inappetence, difficulties with food intake, hypersalivation, scratching of the head, hiding and social avoidance. The animals were sedated by IM darting with a cocktail of dexmedetomidine 0.05 mg/kg, ketamine 3.5 mg/kg and butorphanol 0.3 mg/kg. A clinical examination revealed severe oral inflammation, broken, missed and infected teeth, bone expansion and loss of periodontal attachment, diagnosed by periodontal probing. Dental radiography showed severe alveolar bone loss in the area of the maxillary incisors, connective tissue attachment loss and bone resorption. Under the general anaesthesia, maintained with 2% sevoflurane, dental cleaning was performed by using power scalers. Infraorbital nerve blocks with 0.5% bupivacaine was used for all three surgical procedures. Extraction was the treatment of choice for maxillary incisors, and an open method tooth extraction was performed. Periodontal flaps were used for gingival reconstruction. Postoperative care included analgesia with meloxicam 0.1 mg/kg administered SC once, and then PO for seven more days, and antibiotic treatment with clindamycin 22 mg/kg PO, given with food, for seven days. All three animals were returned to their den immediately after recovery from the surgery. Food was not withheld, and they started to eat within a day. Dental radiography was performed 30 days post-surgery, showing good healing without signs of inflammation or secondary lesions in all three animals.
