Impact of Photobiomodulation on Pain During Orthodontic Treatment

The objective of this study is to determine to effect of PBM Ortho, a photobiomodulation device, in adult patients undergoing clear aligners orthodontic treatment. We hypothesize that PBM Ortho will reduced the orthodontic associated pain in the clear aligner patients. This effect will be evaluated by recording the pain on visual analog scale given to the patients before the placement of clear aligners and collecting saliva.

Detailed Description

Pain associated with orthodontic treatment is one of the main causes of treatment discontinuation and patient non-cooperation. Several treatment modalities have been studied to alleviate orthodontic pain which includes pharmacological, mechanical, and behavioral approach. One potential treatment is the application of photobiomodulation (PBM) therapy which is a form of light therapy. The objective of this study is to determine to effect of PBM therapy in adult patients undergoing clear aligners orthodontic treatment. This effect will be evaluated by recording the pain on visual analog scale given to the patients before the placement of clear aligners and collecting saliva. The patients will be provided with active PBM Ortho device and sham PBM device (placebo, which will look similar to the active device) to use them at home for one 8 minutes application for 7 days (4 minutes per arch, upper or lower). The pain scale sheets will also be given to the patients to fill them every day for 7 days. The inflammatory protein associated with pain present in the saliva will be collected on Day 1 (24 hours after clear aligner treatment start), Day 4 (fourth day of treatment), and Day 7 (after 1 week from the treatment start). On the last visit, the device and pain scale sheets will be collected from the patients. If successful, this device therapy will reduce the orthodontic associated pain and improve patients' compliance and cooperation.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Visual analog scale
Time Frame: Day 0: prior to seating first clear aligner tray
Study endpoint for effectiveness in decreasing the pain perception during orthodontic tooth movement. Pain intensity will be scored between 0 (no pain) and 10 (worst imaginable pain) on the numeric scale. Pain intensity does not have a unit to describe. The pain intensity will be recorded in both groups at Day 0 (after the placement of the first composite attachments on the teeth but before the seating of the first clear aligner), and then every day for 7 consecutive days.
