Table 5. Model analysis; rotational control of molars (angular measurement of the firstmolar with respect to the midline) .

On the left side, there was no change in group B and minimal change in group A. On the right side, mean changes were -0.625^◦ and -0.125^◦ in groups A and B, respectively. The changes were statistically non-significant. P<0.05 was considered as statistically significant. (M = molar, Ang = angulation, RT = right side, LT = left side).
