Table 4.

Vertical differences between canine and central incisor gingival zeniths (GZs)

Subjects	Rightn ( $\bar{x}$ ± SD)	Leftn ( $\bar{x}$ ± SD)	Bilateraln ( $\bar{x}$ ± SD)
Men	38 (−0.23^* ± 1.29)^a	38 (0.14 ± 1.30)^b	76 (−0.04 ± 1.30)^c
Women	53 (0.51 ± 1.17)^a	53 (0.69 ± 1.07)^b	106 (0.60 ± 1.18)^c
Total	91 (0.20 ± 1.27)	91 (0.46 ± 1.19)	182 (0.33 ± 1.23)

$\bar{x}$ , average of x.

SD, standard deviation.

Unit: mm.

Within a column, number values with the same lower-case letter are statistically different (P < 0.05).

A minus value indicates that the GZ of the canine is located coronal to the GZ of the central incisor.
