使用标准参考斑块，由一名观察者观察三次，由第二名观察者观察一次，观察了50个科迪亚克岛爱斯基摩人牙模样本的牙列和颌骨的47个分级和离散形态特征。虽然观察会话之间的观察者内和观察者间的评分差异的频率相对较高的一些字符，统计分析表明，差异在很大程度上是随机的方向和抵消。大多数牙齿形态变异可以观察到一个排名的方式与足够的内部和观察员之间的可靠性。然而，四个特点都存在内部和观察者之间的困难：结节齿状突，犬齿远端副嵴，边缘副尖的上部第一前磨牙，和前凹的下部第一磨牙。
A sample of 50 Kodiak Island Eskimo dental casts were observed, using standard reference plaques, three times by one observer and once by a second observer, for 47 graded and discrete morphological characters of the dentition and jaws. Although the frequency of the intra- and interobserver scoring differences between observation sessions are relatively high for some characters, statistical analysis reveals that differences are largely random in direction and cancel out. Most dental morphological variants can be observed in a ranked fashion with adequate within- and between-observer reliability. However, four traits present both within- and between-observer difficulties: the tuberculum dentale, the canine distal accessory ridge, marginal accessory cusps of the upper first premolar, and the anterior fovea on the lower first molar.
