Effect of Low Level Laser Therapy on Local Bone Resorption During Orthodontic Treatment: A Randomized Controlled Trial

The aim of this study was to assess whether the application of low-level laser therapy (LLLT) during the first stage of orthodontic treatment has an effect on local bone resorption and is detectable at the systemic level by measuring deoxypyridinoline levels (Pyrilinks) in urine. This was a randomiz...

This was a randomized (1:1), double-blind, active-controlled, parallel-group trial. 28 adult patients who were going to start orthodontic treatment were randomly divided into the control group (n: 13) and the experimental group (n: 15), the latter of which received LLLT. All of the subjects underwent testing of urine samples: the first one on the day before the beginning of orthodontic treatment (T0), and the second one 5 days after bracket placement to measure Pyrilinks values (Dpd/Cr) in urine. Group differences were evaluated with Student's paired t-test. At the beginning of the study, the Pyrilinks were in the normal range for 53.57 % of the patients, and 46.43 % had elevated values according to the normal ranges. Only taking into account the normal values at (T0), the average Pyrilinks for control group (T0) were 5.75± 1.20 nM/mM, (T1): 6.02±3.00 nM/mM. For experimental group, (T0) was 5.71± 0.72, and it was 6.63± 0.73 in (T1).There were no significant differences in the Pyrilinks changes. (p= 0.75).
