Table 4. Model analysis; the transverse control for the canine, premolar, and molar teeth from the midline (incisive papilla perpendicular) on the right and left sides .

Parameter	Mean changes (mm)		P-value (two-tailed)
	N=20
	Group A	Group B	Group A	Group B
MID-C –RT	0.125	0	0.334	0.351
MID C –LT	0	0.25	0.334	0.335
MID PM RT	-0.3750	-0.25	0.619	0.619
MID PM LT	0.125	0	0.727	0.727
MID M RT	-0.125	-0.125	1.0	1.0
MID M LT	-0.25	-0.125	0.55	0.55

Minimal transverse changes were observed with the right premolars and molars in both groups, which were statistically insignificant. There was no transverse change in the position of the left canine in group A and the right canine as well as the left premolar in group B. Negative values indicate palatal movement. P<0.05 was considered as statistically significant. (MID = midline-canine, PM = Premolar, M = Molar, RT = right side, LT = left side).
