Measurements were taken of the crown diameter of the anterior teeth of the inhabitants in Miyakojima and Ishigakijima and compared with those of another region. Mesiodistal and labiolingual crown diameters of all anterior teeth in Miyakojima and Ishigakijima were smaller than those in Okinawa. The crown diameters of all anterior teeth in Ishigakijima were smaller than those in Miyakojima. In Ryukyu islands tooth sizes were correlated with geographical locations. But when compared with another region the sizes of Miyakojima and Ishigakijima were not geographically correlated. The degree of regression in Miyakojima and Ishigakijima was higher than that in Okinawa. But when compared with another region, the degree of regression in Miyakojima and Ishigakijima was about smaller than that in another region. Inhabitants of Ryukyu islands were affected by the northern characteristics and the southern characteristics.
