About this study

Official title: Effect of Low-level Laser Administered to the Masseter and Anteriortemporal Muscles Prior to the Induction of Fatigue

The objective of this study is to perform an evaluation of the effect of LLLT on the prevention of fatigue in the masseter and anterior temporal muscles in young individuals with and without TMD.

Read the detailed description

Male and female individuals aged 18 to 23 years will be evaluated. The Research Diagnostic Criteria for Temporomandibular Disorders will be applied for the determination of the presence or absence of temporomandibular disorder. Each group (with and without temporomandibular disorder) will then be randomly allocated into a control group and experimental group submitted to pre-fatigue low-level laser therapy. Before and after the induction of fatigue, all volunteers will be evaluated with regard to the range of mandibular movement, bite force, sensitivity to palpation of the muscles evaluated and muscle fatigue. Low-level laser therapy will be administered to the masseter and anterior temporal muscles prior to the induction of fatigue, which will be induced with the use of chewing gum. The data will be submitted to descriptive statistical analysis. The chi-square test and Fisher's exact test will be used to establish the associations of the categorical variables. Pearson correlation coefficients will be calculated for the analysis of the correlation of the continuous variables.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • low-level laser therapyDevice

    Three points will be irradiated over the masseter muscle (upper, middle and lower bundles) and one point will be irradiated over the anterior temporal muscle of each side of the face in the groups submitted to pre-fatigue laser. The following parameters will be employed: wavelength: 780 nm; energy density: 25 J/cm2; output power: 50 mW; power density: 1.25 W/cm2; and exposure time: 20 seconds per points, resulting in a total energy of 1 J per point. The laser will be applied punctually with a conventional tip in contact with the skin considering an area of 0.04 cm2.

  • Placebo comparatorOther

    The same equipment will be used in the placebo group, but with a pen that emits a red guide light and a warning sound, but without the emission of a laser beam.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change on Bite Force

    A digital dynamometer will be used for the determination of bite force. The measurements will be taken in the region of the 1st molars.

    Measured: 6 minutes

Secondary outcomes (1)
  1. Change on range of mandibular movements

    The individuals will be instructed to open their mouths as wide as possible and maximum active vertical mandibular movement (distance between maxillary and mandibular central incisors) will be recorded with the aid of digital calipers. The individuals will then be instructed to repeat the motion with pressure applied to the maxillary and mandibular teeth to obtain maximum passive vertical mandibular movement with the aid of the calipers. These measurements will be made before and after LLLT.

    Measured: 6 minutes

Questions about this trial

What is this clinical trial studying?

A study testing low-level laser therapy in people with Temporomandibular Joint Disorders, run by University of Nove de Julho at 1 site in Brazil.

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 1 inclusion and 1 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: status not confirmed, as of the sponsor's last update on 6 Dec 2016. 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 Brazil. 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. Some participants in this study may receive a placebo. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Camila HL Godoy, MS (55 11 3262-3166, cami_godoy@outlook.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change on Bite Force (time frame: 6 minutes). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 6 Dec 2016.
