Life threatening hemorrhage associated with a dentigerous cyst in a dog: Case report.

Abstract

Dentigerous cysts are the most common type of odontogenic cysts and arise from an unerupted tooth. These cysts have stereotypical radiographic and clinical findings. They can be extremely invasive but rarely present as a life-threatening emergency. This case report describes the stabilization and treatment of a 6-year-old mixed breed dog with a dentigerous cyst with concurrent life-threatening hemorrhage. The dog presented with severe oral hemorrhage from the mandibular artery and required multiple blood transfusions. It was ultimately diagnosed with a dentigerous cyst. Complications from dental issues and potential life-threatening complications, such as this case, can be prevented by routine annual oral examination and full mouth dental radiographs if an unerupted tooth is suspected.
