Maxillary incisor lingual fossa depth was measured in East Greenland Eskimos. It was shown that the statistical distribution for the trait may vary from population to population, from tooth type to tooth type and between the sexes. Examination of statistical distribution should be a part of studies giving detailed statistical analysis of trait. The statistical distribution is probably compatible with a hypothesis of polygenic inheritance. The correlations across the midline were higher for I1 than for I2, and I1 to I2 correlations were lower than across midline correlations for both I1 and I2. It was shown that the degree of fluctuating asymmetry may vary from one dental trait to another. For lingual fossa depth no population variation in fluctuating asymmetry could be demonstrated, in spite of obvious differences in environmental conditions for the populations compared. No sex differences in fluctuating asymmetry were found.
对东格陵兰爱斯基摩人的上颌切牙舌窝深度进行了测量。结果表明，该性状的统计分布可能因人群、牙齿类型以及性别而异。对性状进行详细统计分析的研究应包括对统计分布的检验。这种统计分布可能与多基因遗传假说相符。I1跨中线的相关性高于I2，且I1与I2之间的相关性低于I1和I2各自的跨中线相关性。结果表明，波动不对称程度可能因牙齿性状而异。尽管所比较的人群环境条件存在明显差异，但对于舌窝深度，未发现波动不对称存在人群差异。未发现波动不对称存在性别差异。
