Laser in Orthodontic Leveling and Alignment

Dental Malocclusion Clinical Trial

Official title:
Outcome of Low-level Laser Therapy Regarding Orthodontic Leveling and Alignment of Mandibular Anterior Segment: A Controlled Clinical Appraisal

Clinical Trial Summary

to evaluate the outcome of LLLT regarding leveling and alignment of the mandibular anterior segment.

Clinical Trial Description

Thirty patients, 18 females and 12 males, were included who had Class I malocclusion with moderate mandibular crowding and an average age was 19.23 ± 3.1years.They were randomly divided into two parallel groups; a control group without laser intervention and a laser group which received LLLT. All patients followed a non-extraction approach using one category of fixed appliance and matching conventional NiTi archwire sequence during 3 months observation period. In laser group, mandibular anterior teeth were irradiated by gallium aluminum arsenide semiconductor laser with 635 nm wavelength, 6.5J/cm2energy density, for 10 seconds at 10 points (0.2 J/point) on facial and lingual aspects. This protocol was started immediately after first wire insertion and then at days 3,7,14 of the first month and repeated for additional 2 months. In both groups, relief of mandibular crowding was assessed by Little`s irregularity index (LII) after 4 weeks (T1), after 8 weeks (T2), and after 12 weeks (T3) intervals. Changes in LII scores were evaluated through scanned 3D models via software. In addition, the monthly rate of OTM was calculated and compared. The level of significance was set at p ≤ 0.05. ;
