About this study
Official title: Evaluation of Treatment Outcome of Lower Incisors Crowding Using Clear Aligners With Laser Acceleration (Randomized Control Study) .
The present study will be performed to evaluate the effect of low-level laser therapy (LLLT) on the rate of orthodontic tooth movement through the correction of lower incisors crowding using clear aligners
Read the detailed description
This study will employ a two-arm parallel randomized clinical trial design with an allocation ratio of 1:1. The study will include participants aged 16 to 23 years with mild to moderate anterior lower crowding and Class I Angle malocclusion, presenting with a full set of teeth excluding wisdom teeth. Eligible participants will be randomly assigned to either the intervention group, receiving LLLT in addition to clear aligner therapy, or the control group, receiving clear aligner therapy alone.
Intervention:
The intervention group will undergo LLLT using the Biolase Epic X device, calibrated to 0.2 W power, 0.16 J energy, and 0.8 seconds pulse duration per point. The laser will be applied to five points on the buccal surface (cervical mesial, distal, middle root, apical mesial, and distal) and four points on the lingual surface (cervical mesial, distal, middle root, and middle apical) of the target tooth. LLLT sessions will be conducted weekly over seven sessions.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Low-Level Laser accelerationProcedure or surgery
This intervention involves the application of Low-Level Laser Therapy (LLLT) using the Epic X device for patients undergoing orthodontic treatment. The protocol is designed to assess the effects of LLLT on pain reduction and treatment efficacy during the initial leveling and alignment phase of orthodontic therapy using clear aligners .
clear aligner therapyProcedure or surgery
Clear aligner therapy involves using a series of custom-made, clear plastic aligners to gradually move teeth into their desired positions. These aligners are worn over the teeth and are typically changed every week as the teeth gradually shift. The treatment process starts with a digital scan or impression of the teeth, which is used to create a 3D model. This model helps in planning the precise movements needed to achieve proper alignment. Throughout the treatment, patients visit their orthodontist periodically to monitor progress and receive new sets of aligners. Clear aligners are popular for their aesthetic appeal and the convenience they offer compared to traditional braces.
| Study group | Role | What they receive |
|---|---|---|
| control group | Active comparator | ten patients treated with removable clear aligner Receives: Procedure: clear aligner therapy |
| Experimental group | Experimental | ten patients treated with removable clear aligner with application of Low-Level-Laser Receives: Procedure: Low-Level Laser acceleration; Procedure: clear aligner therapy |
What is being measured
The primary outcome is the main question the study is designed to answer.
• Little irregularity index
The Little Irregularity Index is a quantitative method used to assess the degree of dental crowding. It measures the linear displacement of the contact points of the mandibular anterior teeth (canine to canine) from their ideal positions. This measurement is taken before and after orthodontic treatment using scanned 3D models, allowing for an objective evaluation of alignment improvement.
Measured: through study completion, an average of 6 months
Secondary outcomes (7)
• Treatment time
The duration of orthodontic treatment, including active treatment phases such as wearing aligners or undergoing procedures like interproximal reduction, is crucially monitored. This active treatment time is distinct from overall treatment duration, which encompasses intervals such as retention phases or breaks between aligner changes.
Measured: through study completion, an average of 6 months
• Number of aligners
The number of aligners measurement involves determining the total quantity of clear aligners required for a patient's orthodontic treatment.
Measured: through study completion, an average of 6 months
• Patient comfort and satisfaction
Patient comfort and satisfaction were evaluated using standardized scales, including Visual Analog Scales (VAS) , to assess pain levels, oral discomfort, and overall treatment experience.
Measured: through study completion, an average of 6 months
• Refinement rate
The refinement rate in orthodontics refers to the frequency and extent of adjustments made to aligners or appliances during treatment to achieve optimal tooth alignment. It is typically measured by assessing the need for additional aligners,
Measured: through study completion, an average of 6 months
• Digital cast accuracy
Digital cast accuracy was assessed using 3D surface comparison methods, comparing intraoral scans with traditional plaster models.
Measured: through study completion, an average of 6 months
• Tooth movement accuracy
This process involved aligning and overlaying 3D models to assess the extent and direction of tooth displacement over time.
Measured: through study completion, an average of 6 months
• Software predictability
3D models were superimposed to analyze the accuracy of predicted tooth movements compared to actual outcomes.
Measured: through study completion, an average of 6 months

Questions about this trial
What is this clinical trial studying?
A study testing Low-Level Laser acceleration and clear aligner therapy in people with Tooth Movement, run by Huda Abdelhakim at 1 site in Egypt.
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 5 inclusion and 4 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 30 Jul 2024. 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 Egypt. 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?
• Little irregularity index (time frame: through study completion, an average of 6 months). 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 NCT06526871, which also lists 16 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 30 Jul 2024; AzTrials last refreshed its copy on 8 Nov 2026.
