This study analyzes and compares the dental size variation and sexual dimorphism of the Highland Beach Mound people, a late southeastern prehistoric aboriginal Florida population (ca. 800-1200 AD) with a somewhat earlier midwestern group (ca. 200-800 AD) and an Archaic sample (ca. 4160-2558 BC). The lengths and breadths of maxillary and mandibular permanent teeth of 99 individuals were measured, and crown surface areas were calculated for the molars. Results indicated that there was little sexual dimorphism. Only the mesiodistal dimensions of the upper P2 and lower C were significantly different at the P less than 0.05 level. In terms of dental size, what appears to be a chronologically based reduction in most points of comparison was seen in all three groups, with the exception of the molars, which were larger in the Highland Beach sample than in the earlier Schultz Mound.
本研究分析并比较了高地海滩丘人（佛罗里达州东南部史前晚期的原住民群体，约公元800 - 1200年）与稍早的中西部群体（约公元200 - 800年）以及一个古代样本（约公元前4160 - 2558年）的牙齿大小变异和性别二态性。测量了99名个体上颌和下颌恒牙的长度和宽度，并计算了磨牙的冠表面积。结果表明，性别二态性较小。仅上颌第二前磨牙和下颌尖牙的近远中尺寸在P小于0.05水平时有显著差异。在牙齿大小方面，除了磨牙外，在所有三组的大多数比较点上都出现了基于时间顺序的减小，高地海滩样本中的磨牙比早期的舒尔茨丘样本中的磨牙更大。
