Effectiveness of a customized intraoral photobiomodulator for accelerating orthodontic tooth movement

Abstract

The aim of this study was to evaluate effectiveness of a Customized Intraoral Photobiomodulator for accelerating orthodontic tooth movement using a split mouth design as only limited studies have been done to compare the effectiveness of LLLT and their iatrogenic effects between experimental and control group in the same individual (split mouth technique) with the help of a customised intraoral photobiomodulator. Consented Patients (n = 15) undergoing orthodontic therapy, diagnosed with Class 1 bimaxillary malocclusion were subjected to experiment based on randomly assigned split mouth design for both experiments in all 4 quadrants. At retraction phase, a customized introral photobiomodulator was given to all patients and the amount of anterior teeth retraction was measured at 1 month interval for 4 months (T0-T4). Apical root resorption was measured by CBCT taken at the beginning of study phase (t0) and end of 4th month (t1). PBM showed an increase in the rate of tooth movement of 4.12fold in the 1st, 2nd and 3rd month. Mandibular canine showed the maximum amount of root resorption whereas the maxillary and mandibular premolars the least. There were similar results when pulp vitality was evaluated where all the teeth in experimental and control side showed positive results to cold test. From our study, PBM is a better method compared to control group as it has shown increased rate of orthodontic teeth movement.
