A micro–computed tomographic analysis of the root canal systems in the permanent mandibular incisors in a Chinese population

Table 1 Root canal number of mandibular incisors in both genders n

Gender	N	Central incisors (n = 53)		Lateral incisors (n = 53)		Total incisors (n = 106)
Gender	N	Single	Double	Single	Double	Single	Double
Male	51	21	4	19	7	40	11
Female	55	24	4	18	9	42	13
Total	106	45	8	37	16	82	24

Gender difference has no statistical significance for each tooth type (p = 0.862 and 0.611 for mandibular central and lateral incisors, respectively)
Single: single canal; Double: double canals
