Tooth identifation in the horse- copyright Academy of Equine Dentistry-2008

Resumen

The formula for deciduous teeth: 2 (I3/3 C0/0 P3/3)

The formula for permanent teeth: 2 (I3/3 C1/1 P3-4/3 M3/3)

Canines

The canines are rudimentary and in diastema. The size of the root is proportionally larger than the crown.

Molars

Diente de Caballo - Copyright Malcom Morley

The molars have enlarged surfaces and higher crowns. They have delayed root development and complicated folding of enamel.

Incisors

Incisors have high crowns and folded enamel surfaces. Their roots converge.

Premolars

A horse's Wolf tooth (PM1) is often lacking. Molars and Premolars form a continuous surface. Premolars have a high rate of wear and continually erupt. The upper teeth are wider than the lower. There is no infundibulum in the lower teeth.

Ageing

Horses can be aged by their teeth. At 2 and a half the first permanent incisor will erupt; At 3 and a half the second permanent incisor will erupt and at 4 and a half the third permanent incisor will erupt. Over 5 years of age the folding of the enamel ring (infundibulum) can indicate age. There is a 7 year hook and over 13 years of age a dental star will be present.

The Galvayne's Groove is a brown groove on the upper corner incisor teeth and indicates that the horse is over 10 years old. At 15 the groove will be approximately half way down the tooth; At 20 the groove will run down the whole tooth; Over 20 the grove begins to disappear; At 25 the groove will only be visible on the bottom half of the tooth. At 30 the groove will usually be gone.

-El '''diente de lobo''' (PM1) del caballo es a menudo insuficiente. Los premolares y molares forman una superficie continua. Los premolares tienen una alta tasa de desgaste y erupciónan continuamente. Los dientes superiores son más anchos que los inferiores. No hay infundíbulo en los dientes inferiores.

-Se puede sacar la edad de un caballo por los dientes. A las 2 años y media erupciona el primero incisivo permanente; A las 3 años y media el segundo incisivo permanentes erupciona y a las 4 años y media el tercer incisivo permanente erupciona. Más de 5 años de edad el plegamiento del anillo de esmalte ('''infundíbulo''') puede indicar la edad. Hay un año gancho de 7 años y a más de 13 años de edad una '''estrella dental''' estará presente.

-El '''surco Galvayne''' es un surco marrón en los incisivos superiores por los lados e indica que el caballo es más de 10 años de edad. A los 15 años la ranura será aproximadamente hasta la mitad del diente; A los 20 la ranura se descargue todo el diente, y a más de 20 el surco comienza a desaparecer; A los 25 la ranura sólo será visible en la mitad inferior del diente. A los 30 la ranura por lo general se ha ido.
