A prehistoric Native American mandible from a Fremont site (circa AD 1025) in Colorado has a conical pit in the worn occlusal surface of the lower right canine. Natural causes for this modification are ruled out by the presence of internal striae, a finding confirmed by experimental replication. The canine was artificially drilled before the individual's death and is associated with a periapical abscess. This is one of a very few examples of prehistoric dentistry in the world, and the first from the American Southwest.
在科罗拉多州一个弗里蒙特遗址（约公元1025年）发现的一具史前美洲原住民下颌骨，其右下尖牙磨损的咬合面上有一个锥形凹坑。内部条纹的存在排除了这种改变是由自然原因造成的可能性，这一发现已通过实验复制得到证实。这颗尖牙是在该个体死亡前被人工钻出的，并且与根尖脓肿有关。这是世界上极少数史前牙科的例子之一，也是来自美国西南部的首例。
