About this study
Official title: Investigating the Effectiveness of Low-Level Laser in Reducing Root Resorption of the Upper Incisors During Intrusion Movement Using Mini-Implants in Adult Patients With Deep Overbite: A Randomized Controlled Clinical Trial
This study aims to investigate the effectiveness of low-level laser in reducing the resorption of the roots of the upper incisors. Participants will be recruited from patients who will attend the Department of Orthodontics and Dentofacial Orthopaedics at Damascus University. The study sample will consist of 30 patients with a deep bite who will be randomly distributed equally into two groups, 15 patients in each group, average age: 22.37±3.38 years. Mini-implants will apply between the roots of the maxillary central and lateral incisor at both sides with a loading force of 40 g on each end by using a nickel-titanium spring extending from the head of the mini-implants to a wire welded to it with two hooks. A low-level laser (Ga-Al-As) will be used with 808 nm wavelength in continuous mode, 250 milli-Watt power output, 4 Joules/point energy density, 16 s per point in the experimental group. It will be applied on the day of intrusion, then on days 3,7, and 14 of the first month, and then every 15 days starting from the second month until the end of the intrusion. In addition to adjusting the force gauge every 4 weeks until the end of the intrusion stage and reaching normal coverage will be activated every 4 weeks in both groups until normal overbite was reached.
Read the detailed description
Several studies have indicated the effectiveness of the LLLT in accelerating orthodontic movement, but studies that have evaluated the role of this laser in reducing the risk of OIIRR have been limited. Moreover, the effects of laser in reducing root resorption have been studied with different types of orthodontic movements such as en masse anterior retraction, canine retraction, and tilting of the premolars before extraction, but they have not been studied with the intrusion movement

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Traditional orthodontic treatmentDevice
As for patients in the control group, the strength of the nickel-titanium coil will be adjusted every 4 weeks to the required strength of 40 g on each end until reaching normal coverage.
Low-Level LaserDevice
The laser will be applied to the root of each of the upper incisors in 8 points (4 points from the labial and 4 points from the palatine), and the head of the device will be placed from the labial side of the root in the center of each of the apical and middle thirds and the mesial and distal of the cervical third in contact with Oral mucosa perpendicular to the root axis, with the application of the laser beam for (16) seconds at one point, and the laser will be re-applied in the same way from the palatal side of the root. So that it was the total application time is (128) seconds for one tooth.
The laser will be applied on the day the upper incisor intrusion started (T1), then on days (3, 7, and 14) of the first month, and starting from the second month, the laser will be applied every (15) day, in addition to adjusting the force gauge every 4 weeks until the end of intrusion stage (T2) and reaching normal coverage.
| Study group | Role | What they receive |
|---|---|---|
| Control group | Active comparator | The strength of the nickel-titanium coil will be adjusted every 4 weeks to the required strength of 40 g on each end until reaching normal coverage Receives: Device: Traditional orthodontic treatment |
| Low-Level Laser Therapy group | Experimental | In the experimental group (LLLT), where a (Ga-Al-As) diode laser, will be used with 808 nm wavelength in continuous mode, 250 milli-Watt power output, 4 Joules/point energy density, 16 s per point. In addition to adjusting the force gauge every 4 weeks until the end of the intrusion stage and reaching normal coverage Receives: Device: Low-Level Laser |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in root volume
The root volume will be measured using cone-beam computed tomography (CBCT) images.
One CBCT image will be taken before starting the incisor intrusion Another image will be taken after the end of intrusion (which is expected to happen within 4 to 5 months) Each root's volume will be calculated using specific software (Mimics 21.0, Materialise NV Technologielaan, Leuven).
This calculation will be performed for the upper incisors (central and lateral incisors).
Measured: T1: One day before the beginning of the incisor intrusion procedure, T2: One day following the end of the incisor intrusion procedure which is expected to happen within 4 to five months.
Change in root length
The root volume will be measured using cone-beam computed tomography (CBCT) images (employing the sagittal view).
One CBCT image will be taken before starting the incisor intrusion Another image will be taken after the end of intrusion (which is expected to happen within 4 to 5 months) Each root's length will be calculated using the 3D viewing software. This calculation will be performed for each tooth in the upper anterior region; i.e., upper central and lateral incisors.
Measured: T1: One day before the beginning of the incisor intrusion procedure, T2: One day following the end of the incisor intrusion procedure which is expected to happen within 4 to five months.

Questions about this trial
What is this clinical trial studying?
A study testing Traditional orthodontic treatment and Low-Level Laser in people with Deep Overbite, 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 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 17 Feb 2023. 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?
Change in root volume (time frame: T1: One day before the beginning of the incisor intrusion procedure, T2: One day following the end of the incisor intrusion procedure which is expected to happen within 4 to five months.). The study lists 2 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 NCT05734092, which also lists 5 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 17 Feb 2023.
