采用多变量分析方法，将青冈岛民牙齿特征的度量和非度量数据与日本本州（东京和京都地区）、冲绳岛民、阿伊努人、绳纹人和弥生人的牙齿特征进行比较。青岛岛民的整体牙齿大小最接近东京居民，比绳文人群、冲绳岛民和阿伊努人大，小一些。比弥生的人口还多另一方面，青岛岛民在牙冠测量的形状因素方面与冲绳岛民相似。在非公制牙齿特征中，青岛岛民与其他人群相比更接近于冲绳岛民。总的来说，青岛岛民与绳文人以及与后者有密切关系的人相似，但在牙齿形态上与弥生人有很大差异。这一发现似乎表明，在孤立的人群，如青岛岛民的牙齿性状可能会提供重要的信息，地理变化，这应该是反映历史的形成过程中的日本人口。
Metric and non-metric data of the dental traits of the Aogashima Islanders were compared with those from the Honshu Japanese (Tokyo and Kyoto areas), the Okinawa Islanders, the Ainu, the Jomon and the Yayoi populations using multivariate analysis methods. The overall tooth size of the Aogashima Islanders is closest to the Tokyo residents, larger than the Jomon population, the Okinawa Islanders and the Ainu, and smaller. than the Yayoi population. On the other hand, the Aogashima Islanders are similar to the Okinawa Islanders in the shape factors of the tooth crown measurements. In the non-metric dental characters, the Aogashima Islanders show a closer affinity to the Okinawa Islanders than to any other populations compared. As a whole, the Aogashima Islanders are similar to the Jomon population as well as those who show close affinities to the latter, and largely differ from the Yayoi population in dental morphology. This finding seems to suggest that the dental traits in isolated populations such as the Aogashima Islanders may give important informations about the geographic variations which are supposed to reflect the history of formation processes of the Japanese population.
