The use of tooth cementum annulations for age determination has been deemed promising, exhibiting high correlations with chronological age. Despite its apparent potential, to date, the tooth cementum annulations method has been used rarely for estimating ages in archaeological populations. Here we examine the readability of cementum annulations and the consistency of age estimates using a sample of 116 adults from the Iron Gates Gorge Mesolithic/Neolithic series. Our examination of the method pointed to several sources of error that call into question the use of this method for estimating the chronological ages of archaeologically derived dental samples. The poor performance of the method in our analysis might be explained by taphonomic influences, including the effect of chemical and biological agents on dental microstructures.
牙骨质环的使用被认为是有前途的年龄测定方法，与实际年龄有高度相关性。尽管有明显的潜力，但迄今为止，牙骨质环方法在考古人群中的年龄估计中很少使用。在这里，我们检查了 116 名来自铁门峡谷中石器时代/新石器时代系列的成年人样本中的牙骨质环的可读性和年龄估计的一致性。我们对该方法的研究指出了几个可能导致质疑该方法在估计考古衍生牙样本的年代的误差来源。在我们的分析中，该方法的性能不佳可能是由于埋藏学的影响，包括化学和生物制剂对牙微观结构的影响。
