Laser Therapy on Controlling Pain During Orthondontic Treatment

Overview

To evaluate the effectiveness of pain reduction on a initial orthodontic treatment by using 810nm Diode laser compared to a placebo. Methods: This study will include two parallels groups, 30 adult patients each (mean age 18 - 40) that will be asked to fill a questionnaire related with pain before starting orthodontic treatment with Tip edge technique. Patients from one of the groups will receive laser therapy on both upper and lower maxillary according to the protocol. The patients from the other group will receive a placebo simulating a laser therapy on both maxillary. After the process, both groups will be checked on different times (12hrs-24hrs-48hrs-72hrs after) by filling a questionnaire related with pain each time.

This is a parallel, double-blind, controlled, single-center clinical trial conducted in systemically healthy subjects requiring orthodontic treatment without extractions at the start of treatment in Bogotá, Colombia. Sixty patients (60) will be randomized in a 1: 1 ratio, to either of the two arms of this trial. This study will consist of a single visit by the patient, in this visit the assembly and activation of the upper and lower orthodontic appliances will be carried out. Measurements of the primary outcome variable will be done remotely through a virtual pain monitoring questionnaire through a visual analog scale (Baseline, 12 hours, 24 hours, 48 hours, 72 hours). After Screening a computer-generated scrambling code will be used for allocation in blocks of 6 to the two treatments. The identity of included patients will not be provided to the trial team, in order to preserve the blinded aspect of the trial. The identity of the research treatment associated with each randomization number will be hidden from the trial team and patients. The final analysis is scheduled for when 100% of the patients (60 subjects) reach the 72-hour evaluation.
