During the analysis of a skeletal assemblage from a medieval cemetery in Nubia (c. AD 500–1550), a young adult female with abnormally developed maxillary incisors was discovered. The possible causes of the two dental anomalies found in this individual and their archaeological context are discussed. The remains are from a medieval assemblage from the Fourth Cataract region of Nubia, which forms part of the Nubian collection curated at the British Museum. The left central incisor has a twinned crown with two root canals, and a supernumerary tooth is present on the right side between the central incisor and lateral incisors. Although two different dental anomalies are present, the bilateral expression suggests that the same biological mechanism could be responsible.

古代异常现象：中世纪努比亚人的孪生门牙和多生门牙


在对努比亚中世纪墓地（约公元 500-1550 年）的骨骼组合进行分析时，发现了一名上颌切牙发育异常的年轻成年女性。讨论了在该人身上发现的两种牙齿异常的可能原因及其考古背景。这些遗骸来自努比亚第四瀑布地区的中世纪遗迹，是大英博物馆收藏的努比亚藏品的一部分。左侧中切牙有一个带两个根管的孪生牙冠，右侧中切牙和侧切牙之间有一颗多生牙。尽管存在两种不同的牙齿异常，但双侧表达表明可能是相同的生物学机制造成的。
