The prediction of the age of a horse from its dentition has been widely accepted as an accurate technique, but recent reports have questioned this belief. In this study the dental features of 434 thoroughbreds of known age were documented and a multiple regression equation was calculated from the 13 dental features which had the highest correlation with true age. The accuracy of the ages assessed by a computer model were compared with the ages estimated by experienced equine clinicians. There was little difference between the accuracy of the computer model and the human observers, and neither method provided an acceptable level of accuracy for ageing horses from their dentition.
根据马的牙齿来预测其年龄已被广泛认为是一种准确的技术，但最近的报告对此观点提出了质疑。在本研究中，记录了434匹已知年龄的纯种马的牙齿特征，并从与实际年龄相关性最高的13个牙齿特征计算出多元回归方程。将计算机模型评估的年龄准确性与经验丰富的马医估计的年龄进行了比较。计算机模型和人类观察者的准确性之间几乎没有差异，并且两种方法都不能为根据马的牙齿判断年龄提供可接受的准确水平。
