摘　　要：对上颌牙齿大小和颅骨大小进行了相关研究。全部上颌牙齿大小与上齿槽弓长和弓宽相关显著或非常显著,与颅围长(右I^2无显著相关,左I^1、左I^2、右I^2、左M^1、右M^1和右PM^1与中部面宽)相关显著或非常显著。在此基础上求出了17个以牙齿大小推算颅骨大小的回归方程。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 coef-ficients 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 I2 and maximum cranial length, the left I1, bilateral I2, right PM1, bilateral M1 and middle facial bteadth, are significant, and the others not significant. On the basis of the significant coeffi-cients 17 regression formulae of estimating cranial size from the tooth size were listed.
