Ageing draft and trotter horses by their dentition.

The research article is a comparative study on the accurateness of ageing draft and trotter horses using their dental features, and establishes that incisor shedding and dental star appearance are the most reliable determinants.

Assessment of Dental Aging Method

• This study examined the dental characteristics of trotter and Belgian draft horses and compared them to the horses’ known ages to assess the accuracy of utilizing dentition for determining horse age.
• Inspecting 212 trotter horses and 189 draft horses ranging from two to 25 years in age, characteristics like the shedding of incisors and the visibility of the dental star (a naturally occurring feature in horse teeth) were considered as prime indicators of age.

Dental Features as Age Markers

• The research found that the shedding of incisors and the appearance of the dental stars are the most accurate indicators of age in both horse breeds.
• In younger horses, there was little variation in the dental arrangement between the two breeds, making these two features reliable for broadly estimating horse age.

Variation between Draft and Trotter Horse Dental Aging

• The research identified breed-specific differences in dental aging patterns; namely, the incisors of draft horses were observed to be more prone to wear and tear in comparison to trotter horses as they aged.
• This wear and tear, or abrasion, was seen as affecting the dental aging process and hence the timing of typical aging markers, like the sequential change in permanent incisors, which was noticed to occur earlier in draft horses than in trotters.
