What dental system is used in dentistry for horses?

• A. Small Animal Triadan System
• B. Universal Dental System
• C. Canine Dental System
• D. Equine Triadan System

Answer: (D)

Equine dentistry uses a numbering method designed specifically for horses, called the Equine Triadan System. It assigns a three-digit code to each tooth, so you can say exactly which tooth you’re talking about. The first digit identifies the quadrant (which half of the mouth and whether it’s upper or lower), while the other two digits locate the tooth within that quadrant and indicate its type. This standardization works for both permanent and deciduous teeth and makes documenting eruption dates, wear, and pathology consistent across clinicians. Other systems mentioned are geared toward small animals or are not the standard in horse dentistry, so they aren’t used for equine charts.
