The overall duration of canine retraction was shortened significantly in the experimental side compared to the control side by a mean of 1.17 month (p = 0.001) in the PG and 1.05 month (p ≤ 0.001) in the LG whereas the difference between the two experimental sides was not significant (p = 0.523; Fig. 7).Fig. 7
