Crown morphology of 85 plaster dental casts from skeletal and living Ainus of less than 1/8 non-Ainu admixture is described and compared for microevolutionary and origins considerations. There is no significant sex dimorphism and few inter-sample differences through time. Inter-observer differences occur where observation standards are poorly established. Ainu teeth exhibit a simplified pattern and have trait frequencies more like those of Polynesians and Micronesians than like Chinese, Japanese or Europeans. There is no dental evidence in support of a Caucasoid origin or close relationship. Similarities outnumber differences between Ainu teeth and those of Micronesians and Polynesians suggestive of a past biological relationship.
对85个来自骨骼和现存阿伊努人、非阿伊努人血统低于1/8的石膏牙模的牙冠形态进行了描述，并为微观进化和起源考量进行了比较。不存在显著的性别二态性，且随时间推移样本间差异较少。在观察标准不明确的情况下会出现观察者间差异。阿伊努人的牙齿呈现出一种简化模式，其性状频率更类似于波利尼西亚人和密克罗尼西亚人，而非中国人、日本人或欧洲人。没有牙齿方面的证据支持白种人起源或密切关系。阿伊努人的牙齿与密克罗尼西亚人和波利尼西亚人的牙齿之间相似之处多于差异，这表明过去存在生物学上的联系。
