Table 1

Descriptive statistics and gender difference for the variables measured.

Variables	Genders	Descriptive statistics			Gender difference
		N	Mean	S.D.	t test	p value
Sum of upper and lower incisors crown width	Males	60	54.065	2.884	4.372	0.001
	Females	60	51.949	2.396
Sum of upper canines and premolars crown width	Males	60	43.464	1.884	4.491	0.001
	Females	60	41.880	1.979
Sum of lower canines and premolars crown width	Males	60	42.492	1.844	4.494	0.001
	Females	60	40.973	1.858

p value ≤ 0.01 is considered highly significant.
