Table 7 Stepwise discriminant analysis for sex estimation from maxillary teeth.
| Teeth | Function | Discriminant function | Wilks’ Lambda | p-value | Accuracy (%) | Cutting point* | ||
|---|---|---|---|---|---|---|---|---|
| Male | Female | Overall | ||||||
| All | Crown dimensions | −20.461+0.838 ×(BL13)-1.219×(BL21)+1.122 ×(MD13)+1.275×(MD16) | 0.758 | <0.001 | 69.2 | 72.0 | 70.6 | −0.011 |
| All | Crown area | −8.521+0.342×(CA13)-0.083 ×(CA21)-0.24×(CA23)+0.066×(CA26) | 0.788 | <0.001 | 63.5 | 68.0 | 65.7 | −0.010 |
| All | Crown module | −18.094+2.107×(CM13)+1.359×(CM16)-1.578×(CM21) | 0.841 | <0.001 | 63.5 | 64.0 | 63.7 | −0.009 |
| BL13 – buccolingual distance of the right canine; BL21 – buccolingual distance of the left central incisor; CA13 – crown area of the right canine; CA21 – crown area of the left central incisor; CA23 – crown area of the left canine; CA26 – crown area of the left first molar; CM13 – crown module of the right canine; CM16 – crown module of the right first molar; CM21 – crown module of the left central incisor; MD13 – mesiodistal distance of the right canine; MD16 – mesiodistal distance of the right first molar. * A discriminant score less than sectioning point indicates a woman. | ||||||||
