Study summary

The aims of this study will be to evaluate if a Lower Level Laser Therapy (LLLT): (1) enhances the levels of important pro-inflammatory chemokines involved in the bone remodeling process; (2) increases the rate of orthodontic tooth movement (OTM) on human subjects.

Study arms

  • Experimental
    Low-level laser therapy and no orthodontic force

    No orthodontic force. Laser is applied on the first day and the premolars is extracted after 24 hours

    Device: Low-level Laser Therapy

  • Experimental
    Low-level laser therapy and application of orthodontic force

    Orthodontic force and Laser is applied on the first day and the premolars is extracted after 24 hours

    Device: Low-level Laser Therapy · Procedure: Orthodontic force

  • Active comparator
    Orthodontic force only

    Orthodontic force is applied and the premolars is extracted after 24 hours, with no laser therapy

    Procedure: Orthodontic force

  • Experimental
    Low-level laser therapy and orthodontic force

    Orthodontic force and Laser is applied and the orthodontic tooth movement is evaluated

    Device: Low-level Laser Therapy · Procedure: Orthodontic force

  • Active comparator
    Orthodontic force with no laser therapy

    Orthodontic force is applied and the orthodontic tooth movement is evaluated, with no laser therapy

    Procedure: Orthodontic force

Interventions

  • DeviceLow-level Laser Therapy

    Low-level laser therapy is applied on premolars that will be extracted for treatment plan reasons

  • ProcedureOrthodontic force

    Mechanical loading is applied on premolars that will be extracted for treatment plan reasons and in canines for tooth movement

What researchers measure

Primary outcomes

  1. Rate of orthodontic tooth movement, with and without low-level laser therapy

    The canine retraction was measured with a digital dynamometer

    Time frame: The quantification of OTM was performed before canine retraction

  2. Rate of orthodontic tooth movement, with and without low-level laser therapy

    The canine retraction was measured with a digital dynamometer

    Time frame: The quantification of OTM was performed after 1 month of canine retraction

  3. Rate of orthodontic tooth movement, with and without low-level laser therapy

    The canine retraction was measured with a digital dynamometer

    Time frame: The quantification of OTM was performed after 2 months of canine retraction

  4. Rate of orthodontic tooth movement, with and without low-level laser therapy

    The canine retraction was measured with a digital dynamometer

    Time frame: The quantification of OTM was performed after 3 months of canine retraction

Secondary outcomes

  1. Chemokine levels in the periodontal tissue after LLLT and orthodontic force

    The chemokine levels were measured in the periodontal tissue after LLLT and orthodontic force by means of a cytometric bead array (CBA)

    Time frame: The chemokine levels were assayed on days 0, 1, 7 and 14 after application of orthodontic force and low-level laser therapy
