The Role of Low Level Laser Therapy in Acceleration of Teeth Alignment in Lingual Orthodontic Patients

Malocclusion, Angle Class I Clinical Trial

Official title: Evaluation of Low-Level-LASER Therapy (LLLT) Effect on Accelerating Orthodontic Tooth Movement For Crowded Upper Incisors Leveling and Alignment in Lingual Orthodontic Patients: A Randomized Clinical Controlled Trial

Status Completed

Clinical Trial Summary

We will treat patients with class I malocclusion who have moderate crowding (4-6 mm) according to Little's irregularity index and asses the efficacy of low level laser therapy in accelerating orthodontic tooth movement .

There is two groups :

1. treated with Low level laser therapy (LLLT)

2. treated traditionally without any irradiation Patients will be randomly allocated in any group and all data will be collected through photographs when leveling and alignment completed.

Also pain levels will be assessed using numeric rating scale to compare between the two groups and if laser really can relief pain or not .

Clinical Trial Description

The time of orthodontic treatment is considered to be one of the most concerns for patients. The study will investigate the effect of low level laser therapy on the speed of orthodontic tooth movement during the correction of moderately crowded anterior upper teeth using lingual orthodontic appliance.

The study will be accomplished with two arms, the first is LLLT arm and the other is the control arm without any active intervention.

Low level laser with a wave length of 830 nm, output of 150 mW, energy of 2 J per point and application time of 15 seconds per point will be applied on each tooth of the six upper incisors according to this protocol: the root will be divided into 2 halves; gingival and cervical. Laser will be applied in the center of each half from both the buccal and palatal sides which means 4 application points and a total energy of 8 j per each tooth.

Within the limits of our knowledge, this is the first study in the world that will study acceleration of orthodontic tooth movement with lingual orthodontic . ;
