Snapshot of Equine Dentistry: Past, Present, and Future
A lecture on Equine Dentistry given by Dr Mike Lowder almost 20 years ago was titled “Who’s Floating Who?” At the time, the experts were mostly charismatic lay “Equine Dentists,” and the dental procedures being taught had not significantly changed, other than improved instrumentation, during the previous century. Furthermore, almost all of the procedures being performed at that time had no scientific basis. Some commonly practiced procedures did not correct the indicating problems, and some procedures were actually harmful to our patients. (Source: Veterinary Clinics of North America: Equine Practice)

Equine Oral Endoscopy
Oral endoscopy is a valuable addition to the equine dental examination process. It enables veterinarians to visualize subtle oral disorders and is a useful client education tool. There are several commercially available oral endoscopic systems on the market. Practitioners can also assemble their own systems. An oral endoscope is used to perform a thorough and systematic oral examination and to visualize normal oral structures as well as oral disorders. It is also used to guide instrument placement during oral surgeries and other dental procedures. (Source: Veterinary Clinics of North America: Equine Practice)

Dental Radiography and Radiographic Signs of Equine Dental Disease
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. The limitations of radiography are discussed with regard to determining the need for adjunct diagnostic techniques and more advanced imaging techniques, such as computed tomography.

Adjunct Extraction Techniques in Equine Dentistry
Adjunct extraction techniques are used when the shape or integrity of the tooth, the shape or size of the patient ’s oral cavity, the location of the tooth, or the location of the proximal teeth prevents or complicates standard oral extraction. Techniques described and discussed include partial coronectomy, tooth sectioning, minimally invasive buccotomy, transbuccal screw extraction, and commissurotomy.

Equine Sinus Surgery
The anatomy of the equine paranasal sinuses is critical to understand to assess the extent of the disease process, the optimal surgical approach, and the ability to drain through the normal nasomaxillary pathway. By following established anatomic landmarks, direct sinus access can be used to further explore the sinus compartments, remove compromised cheek teeth, remove any purulent debris or feed contamination, and establish drainage. Many complications can be avoided or minimized by thoroughly evaluating all sinus compartments and critically assessing the ability of the sinus to drain. (Source: Veterinary Clinics of North...

Equine Nasal Endoscopy
The nasal conchal bullae (dorsal and ventral) are separate, air-filled structures within their respective dorsal and ventral nasal conchae. Computed tomography scans have assisted with the increasing diagnosis of empyema of the nasal conchae. This condition is usually associated with dental or sinus disease. Drainage of affected bullae is considered critical for resolution of clinical signs. The ventral conchal bullae can be easily viewed with a standard 10  mm diameter flexible endoscopy via the middle nasal meatus. This approach can also be used for fenestration of the bullae, using a diode laser, equine laryngeal force...

Update on Equine Odontoclastic Tooth Resorption and Hypercementosis
Equine odontoclastic tooth resorption and hypercementosis (EOTRH) is a progressive, painful disease, affecting incisors, canines, and cheek teeth. Examination findings include gingival inflammation, gingival recession and/or hyperplasia, subgingival swelling, bulbous enlargement of teeth, associated periodontal disease, pathologic tooth fracture, and/or tooth mobility and loss. Current hypotheses include biomechanical stresses and secondary bacterial involvement. Early recognition allows case management, but it is a progressive disease. Owner education is crucial; horses with complete or multiple extractions have a favorab...

Equine Dental Floating (Crown Osontoplasty)
Odontoplasty (floating and occlusal equilibration) is the most commonly performed procedure in equine dentistry. From an anatomic perspective, an irregular occlusal surface, prominent cingula, transverse ridges, and enamel points all contribute to the function, form, and longevity of the equine cheek tooth. With limited reserve crown available and an average functional life range between 18 and 25  years, removal of tooth structure should be conservative. The authors consider a quality oral examination to be the most important dental procedure performed in the horse. Individual tooth evaluation should lead to a specific d...

Genetics of Equine Neurologic Disease
Neurologic disease in horses can be particularly challenging to diagnose and treat. These diseases can result in economic losses, emotional distress to owners, and injury to the horse or handlers. To date, there are 5 neurologic diseases caused by known genetic mutations and several more are suspected to be heritable: lethal white foal syndrome, lavender foal syndrome, cerebellar abiotrophy, occipitoatlantoaxial malformation, and Friesian hydrocephalus. Genetic testing allows owners, breeders, and veterinarians to make informed decisions when selecting dams and sires for breeding or deciding the treatment or prognosis of a...

Genetics of Immune Disease in the Horse
Host defenses against infection by viruses, bacteria, fungi, and parasites are critical to survival. It has been estimated that upwards of 7% of the coding genes of mammals function in immunity and inflammation. This high level of genomic investment in defense has resulted in an immune system characterized by extraordinary complexity and many levels of redundancy. Because so many genes are involved with immunity, there are many opportunities for mutations to arise that have negative effects. However, redundancy in the mammalian defense system and the adaptive nature of key immune mechanisms buffer the untoward outcomes of ...
