Abstract: Ninety male adult skulls from south Chinese and their 698 upper teeth (except M3) were investigated, and the coefficients of correlation between tooth size of each upper tooth category and each of six measured cranial items were computed. The coefficient tests denote that coefficients of correlation between tooth size of each tooth category and the maxilloalveolar length, and maxilloalveolar breadth, the right I2 and horizontal cranial circumference, the bilateral l2 and maximum cranial length, the left I1, bilateral I2, right PM1, bilateral M1 and middle facial bieadth, are significant, and the others not significant. On the basis of the significant coefficients 17 regression formulae of estimating cranial size from the tooth size were listed.
