<b>
Background:</b> Patients undergoing orthodontic treatment experience varying degrees of pain with
separator insertion. A survey of patients’ attitude towards orthodontic treatment revealed that pain
was the most discouraging factor related to their treatment. Moreover, it was the highest ranking
reason for wanting to discontinue care. The purpose of this study was to determine the effect of
low-level laser irradiation on dental pain induced by forces from separators in orthodontic treatment. <div>
<b>Materials and Methods</b>: This study was an experimental clinical trial. Twenty-nine patients were
recruited for this research. Low-level laser irradiation was applied on one half of the maxillary and
mandibular arches for 5 days. The opposite half of the arches was considered the control group.
Laser irradiation was applied for 30 seconds in the alveolar bone between the second premolars,
first molars, and second molars. Pain perception was evaluated with a standardized questionnaire
that was answered by patients before and after laser irradiation. Data was analyzed by Wilcoxon
and Friedman test. P value ≤0.05 was considered significant. </div><div>
<b>Results</b>: The highest pain level was reported at day 1 following separator placement and decreased
gradually until day 5. At day 4 and 5, the pain intensity was lower in the laser group than in the control
group however, this finding was not statistically significant. At day 1 and 3, the pain intensity was higher
in the laser group than in the control group however, it was not statistically significant. At day 2, the
pain intensity was lower in the laser group than in the control group and was statistically significant.</div><div><b>
Conclusion</b>: Our findings suggest that there is no statistically significant difference in pain by using
low-level laser irradiation.</div><hr><p class="MsoNormal" style="text-align: left direction: ltr unicode-bidi: embed"><b>Source:
