Table 7 Stepwise discriminant analysis for sex estimation from maxillary teeth.

Teeth	Function	Discriminant function	Wilks’ Lambda	p-value	Accuracy (%)			Cutting point*
Teeth	Function	Discriminant function	Wilks’ Lambda	p-value	Male	Female	Overall	Cutting point*
All	Crown dimensions	−20.461+0.838 ×(BL13)-1.219×(BL21)+1.122 ×(MD13)+1.275×(MD16)	0.758		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		63.5	68.0	65.7	−0.010
All	Crown module	−18.094+2.107×(CM13)+1.359×(CM16)-1.578×(CM21)	0.841		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.
