This randomized trial examined the efficacy of Low-Level Laser Therapy (LLLT) effectiveness in spontaneous and chewing pain relief after the first orthodontic archwire placement.
In the
quest to find the an
effective way to control orthodontic pain without medicines, the results of
this placebo-controlled,
randomized clinical study
revealed no statistical noteworthy difference in pain scores for any studied
time point between the laser group and placebo concerning spontaneous and
chewing pain except after 72 hours of laser use for chewing pain only.
This
randomized trial examined the efficacy of Low-Level Laser
Therapy (LLLT) effectiveness in spontaneous and chewing pain relief after the
first orthodontic archwire placement.
In this trial, 26 patients (mean age 20.07 ± 3.13 years)
with maxillary Little’s Irregularity Index (LII) of ≥7 mm representing the
first maxillary premolars extraction and no medicine use were considered. They
were randomized to receive either LLL or placebo.
Blinding was relevant for patients only. The patients were given a single LLL
dose (wavelength 830 nm, energy 2 J/point) in 2 points each of palatal and
buccal area for each maxillary anterior tooth root in the laser group. The placebo
group patients had same laser application technique minus the laser beam. After
different time points i.e. 1 hour, 6 hours, 1 day, 2 days, and 3 days of
treatment, the patients scored their sponteneous and chewing pain intensity via
the Visual Analogue Scale (VAS). The mean pain scores between the laser and
placebo groups for both sponteneous and chewing pain at each time point were
compared using the independent t-test.
There were no dropouts. No statistical significance was found for each studied time point (p > 0.05) for both sponteneous and chewing pain apart from after 3 days for chewing pain with a VAS score of 18.84 ± 13.44 mm for the laser group than 38.15 ± 27.06 mm for the placebo, inspite of few clinical differences between the groups represented in following graph:

LLLT was not effective for pain relief
concerning initial orthodontic archwire placement.
