This study aims to evaluate the dental variability and the phenetic relationships among archaeological human populations of the Chalcolithic and Bronze Age in North-Eastern Romania.
The evaluation of phenotypic variability was performed using the 2D Geometric Morphometrics on the second molars (upper - M, and lower - M) belonging to adult skeletons discovered in archaeological sites of the Chalcolithic and Bronze Age in North-Eastern Romania.
The size (Centroid Size, CS) and shape analysis of the second molar highlighted specific characteristics for each prehistoric period. The CS doesn't achieve any statistical significance for two of the comparison criterium used (i.e., period, archaeological site). Instead, statistically significant differences were recorded between males and females. The greater variability in the shape of M compared to M was noticed. The M model of the Bronze Age is flattened mesiodistal compared to the Chalcolithic one, while differences in M morphotypes are associated with the hypocone shape, particularly.
This study of dental morphology provides new data that could contribute as evidence of interactions between biological human groups in different regional prehistoric contexts.
本研究旨在评估罗马尼亚东北部青铜时代和铜石并用时代考古人群的牙齿变异性和表型关系。
采用二维几何形态测量学方法对上、下颌第二磨牙（M 和 M）进行表型变异性评估，这些磨牙属于在罗马尼亚东北部青铜时代和铜石并用时代考古遗址中发现的成人骨骼。
第二磨牙的大小（形心大小，CS）和形状分析突出了每个史前时期的特定特征。CS 在使用的两个比较标准（即时期、考古遗址）中没有达到任何统计学意义。相反，在男性和女性之间记录到了统计学上的显著差异。与 M 相比，M 的形状变化更大。与铜石并用时代相比，青铜时代的 M 模型在近远中向更扁平，而 M 形态的差异与小尖牙的形状有关。
这项牙形态学研究提供了新的数据，可作为不同区域史前背景下人类生物群体之间相互作用的证据。
