• An anthropological study of the oral cavity in various areas of Japan and neighboring country has been conducted to clarify racial lineage. This study examined the dental arches of 114 males and 117 females living in northern Shikoku and of 364 males and 422 females living in Kyushu in whom impressions were taken and plaster models made. The data on the two populations were compared with those of the populations in various areas of Kyushu, Okinawa island and Shimonoseki (Yamaguchi prefecture), obtained in other investigations. The length and the breadth of the dental arch in the northern Shikoku population tended to be longer and smaller, respectively, than those of the Shimonoseki and northern Kyushu populations, but were similar to those of the southern Kyushu and Okinawa populations. The height of the palate in the northern Shikoku population tended to be greater than those of the Shimonoseki and northern Kyushu populations, but tended to be smaller than those of the Okinawa population, especially in the anteriority of the palate. The length of sutura palatina mediana in the northern Shikoku population tended to be longer than that of the Shimonoseki and northern Kyushu populations, but tended to be shorter than that of the southern Kyushu and Okinawa populations. These findings indicate that the dental arch and palate in the northern Shikoku population differ in morphology from those of the populations in various areas of Kyushu, Okinawa and Shimonoseki.
