Clinical Trial Summary

This is a single blind randomized controlled trial with split mouth design including 45 patients with extractions of maxillary 1st bicuspids. First leveling and alignment will take place till 17 × 25 Stainless Steel wire pass passively through all the brackets. Canine retraction will be done through elastomeric ligatures maintaining force of 150gm on both sides. One of side of maxillary arch will be irradiated by diode laser (aluminum-gallium-arsenide) of 980nm on cervical, middle, and apical third on buccal and palatal surface of cuspid and the other side will act as placebo. Laser irradiation will be done at baseline and then for 3 more consecutive visits. Measurements will be recorded from maxillary canine hook to maxillary 1st molar hook at 3 weeks interval till complete canine retraction will be achieved. Patients will be given a questionnaires supported numeric scale to record their pain score for a week.


Description:

First ethical approval for the study is going to be taken from the scientific committee and then Institutional Review Board of Dow University of Health Sciences. After getting informed consent from the chosen study participants, banding and bonding of the maxillary arch are going to be done through conventional fixed appliance Edgewise brackets. Initial leveling and alignment are going to be achieved by using nickel titanium and round stainless-steel wires until 0.017x0.025-inch stainless-steel wire passes passively through all fixed appliance. Anchorage is going to be implemented by skeletal anchorage through mini implants and molar stops on 0.017×0.025-inch stainless-steel wire just mesial to upper 1st molar band slot. As this study features a split mouth design so, every study subject will receive Gallium-Aluminum-Arsenic diode laser with a wavelength of 980nm ± 10nm on one maxillary canine and a placebo effect on the other maxillary canine. The side receiving laser irradiation is going to be alternated with every consecutive patient. To prevent from chauffeuring effect, a plastic shield will be used. The patient will be given questionnaire based scale to record pain score for a week. Distalization of the canines is going to be accomplished by elastomeric chain (Medium span, Ortho Organizer) which can begin instantly after extraction of first premolars. There is no distinction between retraction rate of canines using either elastomeric chain or Nickel Titanium springs. All study measurements will be taken using 0.01mm with digital Vernier caliper considering hook of maxillary cuspid teeth and hook of maxillary 1st molar teeth as reference points. Measurements will be recorded thrice in a single visit and mean is taken to avoid bias. Readings will be recorded after every three-weeks interval until one of the canines is completely retracted. Arch length will be measured on the cast as inter molar width. Patients will be given a questionnaire supported numeric scale to record their pain score for a week.
