Oral traits of Taiwan Aboriginals have been a subject of interest for anthropology. Little, however, has been reported because of geographical peculiarity. Therefore, a study on the Ami tribe, a total of 110 subjects, 41 males and 69 females aged over 16, was made on the plaster casts for the purpose of clarifying their dental arches and palatal traits. Upper and lower dental arch lengths of the Ami tribe were not significantly different between males and females. Dental arch lengths were similar in the Ami females and Taiwanese females and those in the males were shorter in the Ami than in Taiwanese. They were shorter in the Ami tribe than in the Japanese, but longer than in the Paiwan and the Rukai tribes in both males and females. Upper and lower dental arch breadths of Ami were significantly greater in the males than in the females. Dental arch breadth measurements were smaller in the Ami than in the Rukai and Taiwanese, and greater at posterior region than in the Japanese in both males and females. Dental arch breadths were smaller at posterior region in the Ami males than in the Paiwan males, but those at anterior region in the females were greater in the Ami than in the Paiwan. Lengths of dental arch of the Ami were longer in the males than in the females. Lengths of dental arch were similar or slightly shorter in the Ami than in the Paiwan, the Rukai, Taiwanese and the Japanese in both males and females. Anterior and posterior palatal heights of the Ami tribe were significantly greater in the males than in the females. Palatal heights were smaller in the Ami than in the Paiwan and the Rukai, and greater than in Taiwanese in both males and females. Anterior palatal height was smaller but posterior was greater in the Ami than in the Japanese. Length of sutura palatina mediana of the Ami were not significantly different between males and females. Length of sutura palatina mediana was slightly longer in the Ami than in the Paiwan and the Rukai. Palatal arch lengths of the Ami were significantly longer in the males than in the females. Palatal arch length were shorter in the Ami than in the Paiwan, the Rukai, Taiwanese and the Japanese in both males and females. Palatal breadths of the Ami were significantly greater in the males than in the females. Palatal breadths were similar in the Ami males than in the Paiwan and Rukai males, and greater than in Taiwanese and Japanese males. Those in the females were similar between the Ami and Taiwanese, and smaller at anterior region but greater at posterior in the Ami than in the Paiwan and the Rukai. Mandibular alveolar breadths of the Ami were significantly greater in the males than in the females. They were smaller than those of the Paiwan and Rukai, and also smaller at anterior but similar or slightly greater at posterior than those of the Taiwanese and Japanese in both males and females.
