Study Notes

Equine Dental Anatomy and Terminology

Equine adult dental formula is 2(I3/3, C0-1/0-1, P3-4/3, M3/3) totaling 36 to 42 teeth.
Hypsodont describes animals with continuously erupting teeth, characteristic of equine dentition.
Equine teeth grow approximately 2-3 mm per year, affecting dental care practices.

Dental Conditions and Structures

Diastemata refers to the spaces between teeth, which can contribute to dental issues.
Caps are deciduous premolars that may still be present in older horses.
Retained caps occur when baby teeth fail to detach properly post-eruption of permanent teeth.

Specific Tooth Identifications

PM1, also known as the "Wolf Tooth," is commonly found on the maxilla (upper jaw).
The palatine artery is located near the PM1 and is significant in dental procedures.

Age Estimation in Horses

Horses can only be accurately aged until they reach 5 years of age due to changes in dental structure.
The dental star is a pulp cavity mark that appears with wear and aging, first seen as a dark line before becoming oval.

Features of Teeth

Cups are the black cavities located in the middle of the occlusal surface of incisors.
Galvayne's groove appears on the labial surface of the upper I3 around 10 years of age, aiding in age estimation.
Dental stars develop as a dark transverse line in dentin, filling the pulp cavity as the tooth wears down.

Observations on Aging

At 15 years, dental stars appear round in the incisors, indicating progression of age-related changes.

Anatomy and Dental Care

Hyoid bones are described as fragile bones, relevant to equine anatomy.
Floating refers to the practice of filing down hooks, points, ramps, and waves on cheek teeth, necessary for maintenance of oral health.
The surface to focus on when floating maxillary teeth is the buccal surface, while for mandibular teeth it is the lingual surface.

Sedation and Dental Procedures

Common sedatives used for dental procedures in horses include detomidine, xylazine, and butorphanol.

Feeding Issues

Quidding is a condition where horses drop partially chewed food in large rolls, often due to dental problems.
