Abstract

Objective: To compare the effect of LLLT and I-PRF on the rate of maxillary canine retraction following first premolar extraction. Methods: A clinical study was conducted on 28 female patients divided into two equal groups. In Group 1 (n=14), LLLT was applied to the right maxillary canine, while the left served as a control. In Group 2 (n=14), I-PRF was injected around the right maxillary canine, with the left side as control. Canine retraction was measured monthly over four months using casts that were fabricated and then scanned with a 3D scanner Results: Group 1, the LLL side (right), showed a statistically significant higher rate of canine retraction than the control side (left); group 2, I-PRF, showed a statistically significant higher rate of canine retraction over the control side (left). LLLT resulted in a significantly higher rate of movement over the four-month observation period. Conclusion: In both groups the experimental side showed accelerated canine movement compared to the control side, the LLL yielded higher rate of canine movement when compared to I-PRF.
