Abstract: One hundred and eighty-three Chinese mandibles(male 113, female 70) were measured. Statistical test shows that of all 13 measurements 12 have significant sex differences. The sex differences of mandibular ramus height was found most significant. It can discriminate mandibles 80% accurately alone. 11 mandibular sex discriminant functions were calculated by Fisher's method. The discriminant rate ranges from 85.2% to 87.4%.
