Study summary

The primary goal of the study is to determine if there is a difference in pain levels following the use of low level laser therapy versus placebo and control after placement of elastomeric orthodontic separators in pediatric patients. To test this, the investigators will assess the patient's pain levels immediately following separator placement and 24 hours post-operatively but having patients rate their pain on a 10 cm Visual Analog Scale (VAS). Patients will be randomly assigned to one of three groups: treatment, placebo, and control. The aim of this study is to establish whether or not low level laser therapy can be used to reduce pain in pediatric patients following separator placement.

What researchers measure

Primary outcomes

  1. Pain experienced by the patient

    Pain will be assessed via a 10 cm non-hashed visual analog scale at two time points, immediately after placement of the elastomeric separators (time 0), and approximately 24 hours after placement when the patient returns to the clinic for separator removal.

    Time frame: 24 hours

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 31, 2017, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
