Abstract

Introduction: Introduction: With the emerging concept of accelerated orthodontics, the duration of treatment has become a prime concern for the orthodontists and the patients. Modern technology has perfected a new equipment that has become almost indispensable in modern dentistry, in accordance with the philosophy of minimally invasive therapy i.e the laser [LIGHT AMPLIFICATION BY STIMULATED EMISSION OF RADATION]. The purpose of this study was to clinically evaluate and compare the effects of low-level laser therapy (LLLT) and rate of retraction of teeth in conventional and self-ligating bracket systems.
Method: This split mouth study comprised of 20 subjects. The subjects were equally divided into two groups; the first group (Group A) consisted of 10 patients who underwent treatment with low friction self-ligating brackets [Ormco Damon Q] and the second group(Group B) consisted of 10 patients who underwent treatment with conventional straight wire brackets [Koden MBT]. The retraction was carried out in 0.019" × 0.025" SS wires using conventional retraction technique with a constant force of 150 gm. The experimental side was exposed to biostimulation using 810 nm gallium-aluminum-arsenide (GaAlAs) diode laser on days 0,21,42,63,84th of retraction. A total of 10 irradiations for 10 sec per site were given, 5 on the buccal side and 5 on the palatal side of the tooth. A digital vernier caliper with an accuracy of ±0.001 mm was used to measure the distance between the contact points of the maxillary canine and second premolar on 1st and 84th day of retraction.
Result: Rate of retraction was significantly higher in the laser assisted retraction side when compared with conventional retraction side in both DAMON Q & MBT groups, Laser DAMON combination accelerated the orthodontic tooth movement by 5.44% than that of laser MBT combination.
Conclusion: Combination of Laser and self-ligating brackets is a promising method for accelerating tooth movement.
