Similar endoscopic techniques performed with an intraoral camera system have been reported in human and equine dentistry.29 In the rabbit of the present report, a 2.7-mm telescope permitted detailed examination and assisted in successful tooth extraction and abscess debridement. Abnormal ocular or oculonasal discharge can also develop as a consequence of the eye irritation and the rabbit may show signs of discomfort such as excessive blinking and grinding teeth.

We started with antibiotics, vet said it could be 4-6 weeks before we saw results. Systemic problems may also affect the metabolically active apical germinal tissue and odontoblasts.13,19-23, Diagnosis and treatment of dental disease are often complicated by a vague clinical history, examination late in the disease process, variable and nonspecific clinical signs, and the difficulty inherent in performing detailed oral cavity examination in conscious rabbits.
