Dental Radiography and Radiographic Signs of Equine Dental Disease.

Radiography is an important imaging modality and is available to most equine veterinarians providing primary care. Diagnostic radiographic imaging of the equine skull and dentition requires careful positioning and technique. This article is aimed at providing the veterinarian with instructions and guidelines for obtaining diagnostic skull and dental radiographs and a discussion of the radiographic signs of dental disease with case-based examples.

Transcutaneous Lateral Alveolar Ostectomy for Standing Surgical Extraction of Mandibular First Molar in an 8-Year-Old Miniature Horse.

An 8-year-old, 125 kg (275 lb) female miniature horse was evaluated for a persistently thickened left mandible and cutaneous fistula. Pulp horn defects were identified in pulp horns 1 and 3 of tooth 309 and occlusal pulp exposure was detected with a dental explorer. Radiography of the left mandibular dental quadrant revealed changes consistent with apical infection of tooth 309.

Dental Radiography of the Horse.

This step-by-step article describes radiographic imaging of the horse's teeth and paranasal sinuses with standard radiographic equipment. Obtaining radiographs of the horse's skull that are of diagnostic quality can be challenging. The descriptions offered in this article can help practitioners become more comfortable with obtaining diagnostic images, which will improve recognition of radiographic signs of dental and paradental pathology.

Hematologic, Biochemical, and Endocrine Parameters in Horses With Tooth Resorption and Hypercementosis.

Background: Equine odontoclastic tooth resorption and hypercementosis (EOTRH) is a frequently diagnosed condition in adult horses. The underlying etiology is still unknown. Hematologic, biochemical, and endocrine values have not been reported in EOTRH-affected horses.

Building an Oral Endoscope for Use in Equine Oral Examination and Treatment.

The use of oral endoscopy can be very beneficial in that it helps the clinician to perform a more thorough oral examination. However, due to the high cost, most commercially available equine oral endoscopy systems have been out of reach for clinicians who practice equine dentistry outside a large hospital setting. This article details how to set up an oral endoscopy system that can be used on equine patients either in an ambulatory practice or in a hospital setting.

Lingual Malignant Peripheral Nerve Sheath Tumor in a Chinese Pug Dog.

A 9-year-old spayed/female Chinese Pug dog presented for evaluation of a mass located on the rostral aspect of the tongue. An incisional biopsy was acquired, submitted, and interpreted as a possible granular cell tumor based on hematoxylin and eosin, and periodic acid Schiff histopathologic staining characteristics. The diagnosis was supported by immunohistochemical evaluation that was positive for S-100, vimentin, and neuron-specific enolase.

Complications associated with cheek tooth extraction in the horse.

Common indications for cheek tooth extraction in the horse include dental fracture, periodontal disease, severe decay/ caries, mandibular fracture with alveolar/tooth involvement, and periapical abscess. Complications secondary to extraction of cheek teeth are prevalent. Typical complications may include retained root tip(s), collateral damage of neighboring teeth and alveolar bone, mandibular fracture non-union or delayed union, cemental ankylosis, dilacerated root(s), oroantral/oronasal fistula, palatal deviation of cheek teeth, bone sequestration, sinus involvement, alveolar plug failure, and palatine artery laceration.
