About this trial

This is an interventional treatment trial for Dental Malocclusion focused on measuring Low-level laser therapy, Orthodontic Tooth Movement, Leveling and Alignment, Little Irregularity Index.

Eligibility Criteria

16 Years - 25 Years (Child, Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Selection of participants was based on the following criteria:

    1. The age range was from 15 to 25 years.
    2. All permanent teeth erupted (3rd molar not included).
    3. Angle class I occlusion with normal facial proportions.
    4. Moderate crowding in the lower dental arch assessed by Little's irregularity index that requires treatment with fixed appliance using non-extraction approach.
    5. Good oral and general health.
    6. No previous or current periodontal disease.
    7. No systemic disease or regular medication that could interfere and\or affects orthodontic teeth movement.
    8. No evidence of craniofacial anomalies, such as cleft lip and palate or previous history of trauma, bruxism or parafunction.
    9. No previous orthodontic treatment.

Exclusion Criteria:

  • The patients were excluded from the study if they have:

    1. Severe crowding that requires an extraction approach.
    2. Blocked-out teeth that didn't allow for placement of the bracket at the initial bonding appointment.
    3. Poor oral hygiene or periodontally compromised teeth.
    4. Relevant medical history that interferes with orthodontic treatment.
    5. Craniofacial anomalies or previous history of trauma, bruxism or parafunction.
    6. Previous orthodontic treatment.
    7. The deep bite which interferes with orthodontic brackets placement.

5. Study Description

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