| Abstract: | Teeth measurements and observation of cusp types have been made on 1963 permanent teeth of modern Chinese of south China. The mean measurements of total length, length of crown, length of root, M-D diameter and B-L diameter of crown, M-D diameter and B-L diameter at cervix of each tooth category were made. The statistical results on cusp types of each molar category indicates that the number of cusps from MI to M3 tends to reduce. The Carabellis Tuberculum on M1 occurred in 23.8%, and that on M2 in 1.6%. The shovel-shaped I'occurred in 91.8%. |
