The Incidence of Radiographic Lesions of Endodontic Origin Associated With Uncomplicated Crown Fractures of the Maxillary Fourth Premolar in Canine Patients.

Fractured maxillary fourth premolar teeth are commonly diagnosed in canine patients. These fractures are subdivided into uncomplicated and complicated, depending on absence or presence of pulp exposure, respectively. Pulp injury associated with fractures can lead to pulpitis, pulp necrosis, and "lesions of endodontic origin" (LEO) on intraoral radiographs.

Modified Labial Button Technique for Maintaining Occlusion After Caudal Mandibular Fracture/Temporomandibular Joint Luxation in the Cat.

Maxillofacial trauma in cats often results in mandibular symphyseal separation in addition to injuries of the caudal mandible and/or temporomandibular joint (TMJ). Caudal mandibular and TMJ injuries are difficult to access and stabilize using direct fixation techniques, thus indirect fixation is commonly employed. The immediate goals of fixation include stabilization for return to normal occlusion and function with the long-term objective of bony union.

Common Carotid Artery Ligation to Minimize Blood Loss During Oral and Maxillofacial Surgery.

Oral and maxillofacial surgery in veterinary medicine carries the risk of severe hemorrhage due to the great vascular supply of the head. Temporary hemostasis can be achieved with the application of pressure or hemostatic agents, but more definitive treatment may be needed to ensure bleeding will not resume once the patient is awake and normotensive. Actively bleeding vessels encountered during maxillofacial surgery may be inaccessible, and vessels may recoil into bone, sometimes preventing definitive ligation.
