Sex determination is considered an important step in reconstructing the biological profile of unknown individuals from a forensic context. Forensic anthropologists have long used teeth as an additional tool for sex determination as they resist postmortem destruction. In this case the use of population-specific data is necessary since sexual dimorphism varies between different populations. Currently there are no odontometric standards for determining sex in Greek populations. The purpose of this study is to examine the degree of sexual dimorphism in permanent teeth of modern Greeks. A total of 839 permanent teeth in 133 individuals (70 males and 63 females) from the Athens Collection were examined. Mesiodistal and buccolingual crown and cervical diameters of both maxillary and mandibular teeth were measured. It was found that males have bigger teeth than females and in 65 out of 88 dimensions measured, male teeth exceeded female teeth significantly (P<0.05). Canines were the most dimorphic teeth followed by first premolars, maxillary second premolar and mandibular second molar. Although other teeth were also sexually dimorphic they did not have a statistically significant difference in all dimensions. The most dimorphic dimension was buccolingual cervical diameter followed by buccolingual crown diameter. A comparison of sexual dimorphism in teeth between different populations showed that it differs among different groups. European population groups presented the highest degree of sexual dimorphism in teeth whereas Native South Americans the lowest.
性别鉴定被认为是从法医学背景下重建未知个体生物特征的重要步骤。法医人类学家长期以来一直将牙齿作为性别鉴定的辅助工具，因为牙齿能够抵抗死后的破坏。在这种情况下，由于不同人群之间的性别二态性存在差异，因此需要使用特定于人群的数据。目前，希腊人群中还没有用于确定性别的牙测量标准。本研究的目的是检查现代希腊人恒牙的性别二态性程度。对来自雅典收藏的 133 个人（70 名男性和 63 名女性）的 839 颗恒牙进行了检查。测量了上颌和下颌牙齿的近远中冠和颊舌颈直径。结果发现，男性的牙齿比女性大，在测量的 88 个尺寸中，有 65 个男性牙齿明显大于女性牙齿（P<0.05）。犬齿是最具性别二态性的牙齿，其次是第一前磨牙、上颌第二前磨牙和下颌第二磨牙。尽管其他牙齿也具有性别二态性，但在所有尺寸上并没有统计学上的显著差异。最具性别二态性的尺寸是颊舌颈直径，其次是颊舌冠直径。不同人群之间牙齿性别二态性的比较表明，不同人群之间存在差异。欧洲人群的牙齿性别二态性程度最高，而南美原住民的牙齿性别二态性程度最低。
