About this study
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
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 :
- treated with Low level laser therapy (LLLT)
- 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 .
Read the detailed 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 .

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
low level laser therapyRadiation
Also called LLLT, soft tissue laser
low level laser therapy will be used in order to induce tooth movement. 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 Joules/each tooth.
Lingual OrthodonticsDevice
Lingual braces will be used to conduct the orthodontic treatment of patients with moderate level of crowding on the upper dental arch.
| Study group | Role | What they receive |
|---|---|---|
| Lingual orthodontics | Active comparator | Patients will be treated with lingual braces without being irradiation with low level laser therapy. Treatment will go forward in the normal manner. Archwires will be changed in the traditional way. Receives: Radiation: low level laser therapy; Device: Lingual Orthodontics |
| Low level laser therapy | Experimental | Patients will be subjected to low level laser therapy during their orthodontic treatment using lingual braces. Receives: Radiation: low level laser therapy |
What is being measured
The primary outcome is the main question the study is designed to answer.
Duration of tooth alignment
Days required to complete tooth alignment will be counted.
Measured: When the treatment is completed (i.e. tooth alignment is achieved) and this is expected to take 100 days on average
Change in Tooth Alignment at one month
Little's Index of Irregularity will be measured at 30 days after the onset of treatment.
This index is measured on intraoral photographs of patients' teeth. The value obtained will be compared to the value obtained at the beginning of treatment.
Measured: T1: one day before the beginning of treatment; T2: at 30 days after the onset of treatment.
Change in Tooth Alignment at two months
Little's Index of Irregularity will be measured at 60 days after the onset of treatment.
This index is measured on intraoral photographs of patients' teeth. The value obtained will be compared to the value obtained at the beginning of treatment.
Measured: T1: one day before the beginning of treatment; T2: at 60 days after the onset of treatment.
Change in Tooth Alignment at the end of Alignment Stage
Little's Index of Irregularity will be measured when a complete alignment is achieved; this is expected between 90 to 120 days after the onset of treatment.
This index is measured on intraoral photographs of patients' teeth. The value obtained will be compared to the value obtained at the beginning of treatment.
Measured: T1: one day before the beginning of treatment; T2: when alignment of teeth is complete and this is expected to occur within 90 - 120 days
Secondary outcomes (2)
Change in the levels of pain and discomfort
Assessment will be performed using questionnaires via numeric rating scales (NRS) These levels will be assessed during the first stage of leveling and alignment.
Measured: T1: 10 minutes following the insertion of the first wire in the beginning of treatment; T2: at 24 hours post-commencement; T3: at 48 hours; T4: at 72 hours following the placement of primary archwire
Change in Patients' Acceptance
Assessment will be performed using a standardized questionnaire
Measured: (1) one day following the beginning of the treatment, (2) after one week of the beginning of treatment, (3) after 4 weeks, (5) at the end the alignment stage which is expected to occur within 3 to 4 months

Questions about this trial
What is this clinical trial studying?
A study testing low level laser therapy and Lingual Orthodontics in people with Malocclusion, Angle Class I and Crowding, run by Damascus University at 1 site in Syria.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 18 Jul 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Syria. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Duration of tooth alignment (time frame: When the treatment is completed (i.e. tooth alignment is achieved) and this is expected to take 100 days on average). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03646942, which also lists 6 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Jul 2019.
