Equations to estimate sex using pulp volume

Tooth	Age condition	Logistic regression equation	R² adjusted	p values
Upper central incisor	Known age	Logit Sex = −33.258+(0.823 x central incisor volume) + (0.378 x age)	0.649	<0.0001
	Unknown age	Logit Sex = −0.840+(0.039 x central incisor volume)	0.047	0.047
Upper canine	Known age	Logit Sex = −40.655+(0.818 x canine volume) + (0.395 x age)	0.770	<0.0001
	Unknown age	Logit Sex = −2.040+(0.069 x canine volume)	0.148	0.001
Both teeth	Known age	Logit Sex = −41.614+(−0.747 x central incisor volume) + (1.411 x canine volume) + (0.364 x age)	0.812	central incisor <0.0001
				canine <0.0001
	Unknown age	Logit Sex = −5.442+(−0.517 x central incisor volume) + (0.549 x canine volume)	0.393	central incisor <0.0001
				canine <0.0001
